Suggested March 2024 Beddr’s Sleeptuner Is A Powerful Standalone Alternative To Apple Watch Sleep Tracking

Health startup Beddr today announced its new SleepTuner product, which it says is the first FDA-registered consumer sleep wearable. The wearable connects via Bluetooth to your iPhone, and offers an incredibly detailed look at your sleep quality, heart rate, and more.

While the Apple Watch is capable of tracking sleep with the use of third-party applications, the Beddr SleepTuner takes a slightly different approach. It’s not necessarily a competitor to the Apple Watch, but rather a simplified version of take-home kits offered by many sleep labs.

The Beddr SleepTuner itself is a small sensor that weighs in at 5.3 grams that you place on your forehead using medical-grade adhesive. Beddr says it’s the size of a postage stamp. As you sleep, the device tracks data including heart rate, stopped breathing events, sleep position, blood oxygen, and more. Factors such as sleep position are tracked using optical sensors a 3-axis accelerometer.

Using optical sensors and a 3-axis accelerometer, the SleepTuner goes beyond basic sleep trackers to accurately measure SpO2, stopped breathing events, heart rate, sleeping position, movement and awakenings. Data is securely stored in the Beddr Cloud until it is synced with the Beddr app via Bluetooth.

All of the collected data is subsequently transferred to the Beddr SleepTuner iOS application. Here, you can see sleep quality, sleep duration, average hourly oxygen saturation level, sleep position data, and more.

One interesting thing to note is that Beddr says the SleepTuner is not necessarily designed to be worn every night. Instead, it recommends you wear it for a few days in a row at the start and see what areas the app recommends you direct your focus. From there, you can wear it on a “weekly or monthly basis to trend your sleep quality over time.”

Apple itself acquired hardware sleep tracking platform Beddit last year. But since that acquisition, all that’s changed is the future of Beddit’s cloud service, which will shutdown next month.

Beddr originally teased its SleepTuner accessory over the summer, but now the company says it will be available to the public next month. The accessory will cost $149 and can be reserved via the Beddr website now. Full press release below:

Beddr launches SleepTuner™ – the first FDA-registered sleep wearable to improve your sleep in a week

Clinical-grade connected sensor and mobile app gathers nightly sleep data, provides personalized health insights to improve sleep quality

Mountain View, Calif. (October 18, 2023) – Beddr today launched SleepTuner™ – the first FDA-registered consumer sleep wearable that can assess and help you improve sleep quality, which is now generally available in the United States. SleepTuner integrates an ultra-compact, clinical-grade sleep sensor with an iOS mobile app to provide deeper, personalized insights into your sleep quality and actionable recommendations on how to improve it.

One billion people worldwide suffer from sleep apnea, a disorder in which breathing repeatedly stops and starts during sleep, and even more suffer from poor quality sleep. Beddr is making the essentials of a traditional sleep lab available to anyone from the comfort of their own homes and on their own time. SleepTuner captures much of the same clinical data and accurately measures blood oxygen (SpO2), heart rate, sleep position and stopped breathing events.

“Poor quality sleep can lead to a greater risk of a variety of chronic conditions, like type 2 diabetes, hypertension and depression” said Mike Kisch, CEO and co-founder of Beddr. “The key to better sleep is breathing, and SleepTuner provides access to insights on oxygen levels that cannot be found in traditional consumer sleep trackers. We aim to empower anyone to figure out the cause of their poor sleep within a few days in the privacy of their own home.”

SleepTuner sensor

The SleepTuner sensor takes many of the complex electronics and sensors of traditional overnight sleep labs or take-home kits and condenses them into a discreet, user-friendly wearable. The size of a postage stamp and the weight of a nickel, the sensor is designed for comfort and ease-of-use when worn while sleeping over the course of multiple nights. The SleepTuner is attached to the forehead by a hypoallergenic disposable adhesive. Key to the design of the sensor is making sure it does not disrupt a user’s sleep like the existing options, which involve numerous wires and attachments that can affect comfort and ultimately sleep.

Using optical sensors and a 3-axis accelerometer, the SleepTuner goes beyond basic sleep trackers to accurately measure SpO2, stopped breathing events, heart rate, sleeping position, movement and awakenings. Data is securely stored in the Beddr Cloud until it is synced with the Beddr app via Bluetooth.

In a recent study conducted at the UCSF Hypoxia Lab, the Beddr SleepTuner was found to be accurate with an error margin of only +/- 2.2 percent when compared to an arterial blood draw, which is within the FDA allowable error margin of +/- 3.5 percent. This data indicates that the Beddr SleepTuner is able to accurately measure oxygen saturation levels, a key indicator of risk for sleep breathing disorders like sleep apnea.

Beddr iOS app

The Beddr app is designed to let you measure success night-to-night and build insights at your own pace. The SleepTuner sensor connects with the free iOS app, guiding users through the Beddr sleep tuning process, optimally over the course of a week. The Beddr app combines the data collected by the SleepTuner sensor with self-reported sleep hygiene information to help users determine their optimal sleep position, overall sleep quality, stopped breathing events, oxygen saturation levels and night-to-night improvements.

“The vast majority of people with sleep problems have yet to be diagnosed. SleepTuner represents a promising opportunity to reach a larger portion of the population, engage them in sleep health, and identify issues that may need attention from a doctor,” said Meir Kryger MD, professor of medicine at Yale School of Medicine, former president of the American Academy of Sleep Medicine, and member of Beddr’s Scientific Advisory Board. “The ability to get personalized insights, over multiple nights in your own bed, is a significant improvement in the patient experience.”

SleepTuner is available for purchase at $149, includes the sensor, 12 adhesives, a charging cable and protective case.

How To Track Sleep On Apple Watch In Watchos 9

Things to know:

With watchOS 9, Apple has improved the efficiency of sleep tracking.

Apple Watch should have more than 30 percent charge to use this feature.

You can get sleep-tracking data from the Sleep app on your iPhone and Apple Watch.

Experiencing the Apple ecosystem is bliss for many, thanks to how each device is integrated. Individually, all have their specialties because of the integrated hardware and software features. If you own an Apple Watch, you may have heard about the new and improved sleep tracking with watchOS 9.

So how can you use your Apple Watch to track sleep? Well, that’s what we are going to explore in this guide.

How does sleep tracking work on Apple Watch?

Sleep tracking is a feature integrated with the Sleep app on iPhone. With this app, you can use your Apple Watch for sleep tracking and get information such as the time spent on each sleep stage, REM, and even tips on improving your sleep.

Your Apple Watch will kick off sleep tracking depending on your motion data. Sleep tracking automatically occurs once you have activated the app and enabled the sleep schedule. Now that you know what sleep tracking is, let’s look at how you can set up and track sleep with watchOS 9.

Set up Sleep app on Apple Watch

To track your sleep using Apple Watch, you must first set up the Sleep app.

Powerful Thin Clients May Be Alternative To Pcs

Thin clients introduced this week by Dell and Hewlett-Packard have faster processor than existing thin clients as well as high-definition graphics capabilities, so they could be alternatives to traditional PCs as computing continues moving to the cloud.

Dell introduced its first quad-core thin clients called the Wyse D90Q7 and Z90Q7, and also its first dual-core thin client, the Xenith Pro 2. HP upgraded its TM40 thin client to run Advanced Micro Devices’ A-series processors code-named Richland, which are an upgrade from Intel’s third-generation Celeron processors. The thin clients are optimized to work with Citrix’s virtualization stack, which includes Xen hypervisors and server and client software.

The latest thin clients are PCs with network connectivity but no local storage. Virtual desktops on thin clients typically run applications stored in remote servers, using virtualization technologies from Microsoft, Citrix and VMware. The new thin clients have the ability to run high-definition games delivered over the cloud or full instances of Windows 8 complete with touch interaction.

Faster chips boost client-side processing needed to run data-intensive applications locally.

Old idea with new twist

Thin-client computing is an old idea, but the cloud puts a new twist to the model, said Bob O’Donnell, program vice president for clients and displays at IDC.

Smartphones are tablets are being viewed as thin clients because of their ability to host applications processed on remote servers. But there remains a demand for static thin clients to run applications hosted on servers.

The new, powerful thin clients fit into the emerging cloud model as more applications are centralized to data center, and enterprises can contemplate upgrading Windows XP PCs to thin clients that can host instances of Windows 7, O’Donnell said.

The thin-client devices cost less compared to PCs, but the actual implementation of a cloud-based computing model with the software and server resources could be expensive, O’Donnell said.

In thin-client deployments, a lot of processing happens on the server side. However, powerful thin clients are needed as applications rely more on graphics or heavy client-side processing.

“There are situations when having the extra performance locally is beneficial,” O’Donnell said, providing examples such as virtualized graphics or enterprise applications.

Swap workstations for thin clients?

Dell has played with the idea of replacing full-fledged workstations with thin clients. The company this month introduced a graphics-processor heavy workstation for data centers called the Precision R7610 that serves up multimedia and engineering applications to users over the cloud or in virtualized environments via thin clients. Nvidia, IBM, Dell and others have introduced servers that make high-performance computing resources available to remote computers.

Benefits of the Dell and HP thin clients could also apply to point-of-sale terminals, where an application would need enough processing power to operate the graphical user interface, take orders and pump information back to the data center, O’Donnell said.

“More and more retailers have self-service check out,” O’Donnell said.

Software, throughput and networking improvements also help the new thin clients host more powerful virtual desktops. Dell’s thin clients can run virtualized high-end graphics with improvements made by Nvidia to its VGX virtualization technology, which allows graphics boards to render more virtual machines. The thin clients will be able to run full high-definition 1080p virtualized graphics, which could help in 3D modeling and engineering applications.

HP focused on boosting the throughput to thin clients, with improvements to its Velocity software to cut latency and congestion over wired and wireless networks. Velocity, which is included in HP’s thin clients, adapt to network conditions. Other enhancements improve remote graphics capabilities on thin clients, HP said in a statement.

Adapting Iphone And Apple Watch To A 3

It’s easy to dismiss how reliant a modern lifestyle is on the ability to constantly charge batteries and consume large quantities of data over WiFi. Even minor interruptions to internet and electrical services can be frustrating inconveniences, but how do iPhones, Apple Watches, and Macs fare during an extended period off the grid? I unexpectedly found out this week.

Shortly after noon on July 20th, a round of severe storms sent a large cedar tree crashing to the ground in my front yard, severing the power and communication lines running to my home and office. Outages were widespread throughout the entire region, with countless trees and utility poles snapped. Cell towers were even offline for several hours. Maintenance crews began a 24/7 operation to restore service to nearly 170,000 customers in rural areas. Severe weather of this caliber is highly uncommon along the northern edge of the Midwestern United States.

While most family and friends had power and internet restored within about a day, the single line running from my house to the road was a low priority for a crew overworked and stretched thin tackling larger outages. Power wasn’t restored until the afternoon of July 23rd, roughly 76 hours later. Internet service remains disconnected as I write this.

The tree that disconnected my power and communication lines.

Low Power Mode

MacBooks could benefit from Low Power Mode, too. Switching from the power adapter to battery power already enables a number of energy-saving features, but a toggle for further performance optimizations — like freezing background apps — could significantly improve power-hungry macOS. My MacBook was the most challenging device to keep charged by far, especially since it can’t be fed with a standard portable USB-A power bank.

Personal Hotspot

I’ve used Personal Hotspot on my iPhone more in the past four days than in the four years prior to this outage. Sharing cell data with my MacBook has been critical for working while my home internet is down. Personal Hotspot is perfect for brief tethering sessions, but falls short for sustained use, especially when carrier overages are costly.

Data usage controls would make Personal Hotspot much more useful and economical. As of today, there’s no way to view how much data individual devices are using while tethered. On recent iPhones, the display notch also prevents you from viewing how many devices are connected in the status bar.

Low Data Mode

Similar to Low Power Mode, the addition of Low Data Mode on macOS could further alleviate cell data constraints. iOS 13 will add this capability to iPhones when it launches later this year. Some individual apps already have data control settings for features like autoplay video and high-resolution photos, but a system-wide toggle ensures nothing falls through the cracks. As it stands today, keeping a Mac connected via Personal Hotspot at all times is largely impractical without an unlimited data plan.

Data sharing between devices with the same Apple ID also has the potential to cut down on cellular usage. For apps present on both iOS and macOS like Messages, Mail, and Photos, data could theoretically be passed locally between devices instead of downloaded multiple times over the same cell connection.

Apple Watch

I charge my Apple Watch nightly no matter the circumstances and have been fortunate enough to never run the battery dead since upgrading to a Series 4 model last fall. Faced with the need to stretch my batteries as long as possible, I was pleasantly surprised by how long the latest Apple Watch can remain off a charger. Between Saturday morning and Monday evening, I only needed about 20 minutes of charging time to keep my watch running with a healthy margin of battery life. I minimized notifications and turned off WiFi to conserve power, but didn’t need to enter Power Reserve, dial back the display brightness, disable background app refresh, or enable Power Saving Mode in the Workout app.

The flashlight toggle first added in watchOS 4 is also surprisingly useful. I’ve never had a real reason to use it before aside from novelty, but in a pinch it just might be more useful than the iPhone’s flashlight because you can use it hands-free.

If you have a recent Apple Watch, don’t dismiss the feature as a gimmick — the 1,000-nit display is brighter than you might expect.


I’ve been slow to adopt HomeKit devices into my lifestyle, but with power restored and internet service still disconnected, I’m grateful only a few of my lights are smart. The HomeKit fixtures I do have are mostly inoperable right now, making them even less convenient than my standard lights and switches. Extended outages like mine are uncommon, but it’s worth considering the possibility of a similar event happening at your own home before throwing out all of your standard fixtures. Needless to say, my HomePod has also been reduced to an elegant paperweight.

Overstaying my welcome at Starbucks helped minimize data overages.

How Durable Is The Apple Watch Ultra?

Kaitlyn Cimino / Android Authority

Modern smartwatches must withstand much daily abuse, even more so if used in extreme situations. Garmin has long offered these users rugged devices for use outdoors. More recently, Apple has joined this segment with the Apple Watch Ultra. But just how durable is the Ultra, and how far can it be pushed? We have the answer below.

How does this compare to other smartwatches?

Kaitlyn Cimino / Android Authority

Its use of high-end materials ensures that the Apple Watch Ultra finds itself among stellar company.

The Apple Watch Ultra has a massive leg up with deep water credentials. Garmin and Samsung do not recommend users scuba dive with their aforementioned devices. The HUAWEI GT 3 Pro has a free diving sports mode, but the device is only suitable for dives of up to 30 meters, while the Suunto 9 Peak Pro’s depth meter tops out at 10 meters.

What does it take to break the Apple Watch Ultra?

Kaitlyn Cimino / Android Authority

The Apple Watch Ultra isn’t just a pretty face. It seems that Apple was rather conservative in outlining its limitations.

Water pressure

Let’s talk about diving pressures first. Device reviewer DC Rainmaker pushed the device to the limit in a pressure chamber to simulate deep water dives. While the Apple Watch Ultra displays a “Beyond 130ft” warning on its screen when reaching that depth and beyond, this isn’t a hardware issue. Instead, it seems that Apple is sticking to the recommended depth of a recreational dive.

The actual simulated depth during the test was 159 feet or 48.5 meters — 8.5 meters over Apple’s 40-meter guideline. More impressively, the watch was fully functional after the test. You’ll unlikely damage the Apple Watch Ultra during a recreational dive.

Drops and scratches

You won’t have to worry too much about dropping your Apple Watch Ultra from hand height. YouTuber TechRax did just that on a paved driveway. The watch’s screen was undamaged, but the chassis did show pitting and scratch damage. The YouTuber also rattled the watch around in a bottle full of screws and nails to simulate… something. Again, the device showed no signs of critical damage.

For more realistic conditions, ZDNet‘s Matthew Miller put the Apple Watch Ultra through the Tough Mudder. This obstacle-filled endurance marathon includes “an ice-cold water pool full of shocking ‘Electric Eels’ and mountains of mud-filled barricades.” It sounds like a fun weekend out, so how did the Apple Watch Ultra do? “To my surprise, it held up really well and I still cannot believe that the display is flawless,” wrote Miller.

Blunt force

In the same video, TechRax hammered the Apple Watch after it survived the drop tests. Impressively, the device endured several violent hits directly to the lens, but the table the watch is sitting on broke first. After around 12 hits, the Apple Watch Ultra’s display switched off, but the lens remained unscratched. This suggests a component within the watch broke before the chassis or lens. That’s pretty remarkable.

YouTube channel iupdate also tested the Ultra’s shock resistance against the Series 8. The two watches were put through a series of extreme “tests.” Both devices mostly survived general durability tests, including falling, rock and gravel rubbing, and river soaking. The Series 8 came out rather injured, with several scratches and dings to its lens. The Ultra was mostly untainted.

More extreme tests included smashing both devices against a wall. The Series 8 broke immediately. The Ultra endured 38 throws against the road before the titanium chassis displayed weakness. After “50 impacts,” the device was still functional, bar a few dead pixels. It failed two smashes later.

How easy is the Apple Watch to repair?

Dhruv Bhutani / Android Authority

Of course, if you’re planning to smash you device against a mountain face for a few hours, you may have to have your Apple Watch Ultra repaired. But how possible is this, and how much will it cost?

According to iFixit, the Apple Watch Ultra is among the more tricky wearables to fix. While there’s considerably less strong adhesive in use, and the presence of screws is a welcome sight for home tinkerers, the screen is difficult to remove and battery replacement is also particularly tricky.

If you aren’t interested in fixing your own watch (highly understandable), Apple offers Ultra repairs at a premium. You’ll pay $99 for a battery replacement, while “other damage” will cost $499 without AppleCare Plus or $79 with it.

Is the Apple Watch Ultra worth buying?


Screen protectors are always a good idea, but the Apple Watch Ultra likely won’t require additional protection for its sapphire crystal lens.

Apart from its rugged build, the Apple Watch Ultra also sports a larger battery than any other Apple Watch. In addition, it features dual-frequency GPS, a depth meter and water temperature sensor for diving, unique features for hikers, a skin temperature sensor, and a programmable Action button.

Yes. All Apple Watch Ultra models feature LTE connectivity, but you must pay for the data plan separately.

It’s waterproof on the same level as most diver’s watches, with a speaker that pushes water out after submersion.

And in addition to all the new features, it comes in ceramic now:


There’s also a runner-specific Apple Watch partnered with Nike. The Apple Watch Nike Plus:

Apple Watch Nike+

Apple Watch Nike+ makes you a better runner.

It has tons of features to encourage you to run more, run smarter, join running meet-ups, and comes in four colors.

Both products will be priced at $369, Series 2 will be available this month and Nike+ in October. Oh, and if you want a cheaper option, the original Apple Watch “Series One” will get the new processor as an upgrade and retail for $269.

And, perhaps most importantly of all for some potential wearers: Pokémon Go is coming to the Apple Watch with a special app designed to let you hatch Pokémon eggs on the go.
