About AutoSleep
Using Advanced Heuristics AutoSleep works out how long you've slept so you don't have to.

If you DO wear your Watch to bed, you don't need to do a single thing. AutoSleep will track your sleep & quality and send you a notification in the morning.

Even if you don't wear your Watch to bed, AutoSleep can track your time in bed. It's extremely simple. If you DON'T wear your Watch to bed, then simply take your Watch off before you go to sleep. As soon as you touch your iPhone or put your Watch back on in the morning then AutoSleep will know that you have finished sleeping.

As everyone is a little bit different. AutoSleep provides a simple setup wizard and an option to tweak if you are a very restless sleeper.

AutoSleep also integrates beautifully with the Eclipse Yourself and HeartWatch apps, our premier heart, health, activity, recovery and readiness monitoring apps.

*Requires Apple Watch running WatchOS 4 or higher.

Genuinely life changing

This app is by far the most accurate I’ve come across. I’m a shift worker and other apps usually try to separate sleep into days, whereas this one records accurately whatever time of day I’m sleeping. If I’ve ever fallen asleep on a plane, or on the sofa, it’s caught it, and recorded it. The deep and light sleep seems to roughly correlate, and it records when you are awake at night

Life changing is a big statement I know, but for me it has been. The app allowed me to notice things that help me sleep better. For example, I noticed that on the days post night shift that I just fell into bed and didn’t have breakfast, I woke up 2 hours earlier. On the days that were emotionally tough at work, it took much longer for me to fall asleep (I now meditate on those evenings instead of watching tv). On days or evenings that I had been drinking, I got next to no deep sleep, so still woke feeling tired

In a world where we are always looking for external validation, this works. I can ‘feel’ if I’ve not had enough sleep, but being able to see it clearly in front of you helps to correct sleep or plan for sleep. I feel MUCH less guilty taking a nap in the middle of the day, when I can see that if I do, I will reach a sleep goal, and it has helped me make healthier choices when it comes to sleep. Sleep affects everything, so it’s worth putting some work in to

One of the most in-depth sleep apps...

I’ve been using this app for around 3 weeks, and it is probably one of the most in-depth sleep trackers on the App Store today. Other sleep apps such as Pillow on the App Store offer similar services, but if you’re looking for something to track your sleep just by going to bed, you’re in the right place. Optionally you are able to press the button on your Apple Watch to tell the App you’re going to bed and it will tell you how long it takes to fall asleep at night. If you’re like me and don’t sleep very well (I’m disabled in a wheelchair) it is an interesting statistic to add to your Health data.

Be advised though, if you are somewhat inactive during the day for example, sitting watching TV, playing a game on a laptop, or Xbox; the app may detect that through your inactivity “you are asleep” when you’re actually wide awake defeating a whole lot of baddies on that level you’ve been stuck on... but the app being as in depth as it is, allows you to go into your day and adjust accordingly, and instantly updates through your Health App on your next visit. I’ve found myself opening this app when I wake and comparing my sleep data to the previous days and being given some interesting information.

Intuitive, in depth and a comprehensive app for your sleep data. Fantastic app for all kinds of sleepers.

Best sleep out there

I’ve had this for just about a week and I think I have at last found the perfect sleep tracking application. I’ve tried all sorts of apps in the past, including Withings, Garmin, Huawei and Fitbit with the last one being the best of that bunch by quite a long way. However, even Fitbit was far from perfect, as it seemed somewhat pessimistic and rarely captured evening sofa naps. Autosleep, when used in conjunction with my Apple Watch, provides a wealth of information and, as far as I know, is the only one where you can edit the details of your night’s sleep to make them more accurate. It also captures those elusive sofa naps. If there is one small thing to criticise, it is that the sleep stats do not extend to REM sleep, merely deep and “quality” sleep. However, I seriously doubt if REM sleep can be tracked anyway, as the results for REM sleep with the other apps seem fairly random. The graphical interface with its clocks and circles is great, though can seem a little overwhelming at first. Last but not least at £2.99 as a one off fee, this is a fantastic bargain. I have no hesitation in recommending it.
