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.

If you wear your Apple Watch to bed*, AutoSleep will also analyse your sleep quality. By using time asleep, restlessness, time awake and heart rate it can score the quality of your sleep and provide you with a comprehensive nightly analysis.
*Note. If you do not wear your Watch to bed, AutoSleep simply captures the amount of time sleeping.

AutoSleep also works with HeartWatch our premier heart & activity monitoring app and writes your Sleep information to Apple Health.

*Requires Apple Watch running Watch OS 4 or higher. WatchOS 5 recommended.

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.

Like personal sleep research

I’ve been using this sleep app for a few years now, I just realised. The app provides so much information for every single night (& naps too) that it’s become integrated into my whole way of understanding my lifestyle and health.
Let me explain. This app offers graphic descriptions in chart, wheel, statistical and graph forms. I naturally gravitate toward specific info everyday, but sooner or later I look at all of it. As I compare and contrast the nights of sleep, I naturally ponder what made the difference in quality of sleep. Experimenting with how late I ate before sleep, one example, I discover the latest time I can eat without negativity impacting my ability to fall to sleep effortlessly.
Oh and speaking of falling to sleep effortlessly, that was an impossible feat when I first started using this app! Now I’ve come to know the joy of sufficient energy to get things accomplished in a day... because of a good night’s sleep. Wow. That, my friends, is like reclaiming my life.
Long story short - use this app if you really want to get to the bottom of your sleep issues, like insomnia and interrupted sleep.
