However when I first wake up I’m less than alert and may forget for a while to turn it off. If that happens you can’t edit your wake up time so you’ll have way more restless time recorded than is accurate. (It doesn’t show time awake like my previous tracker). Also if you accidentally hit the sleep button again instead of holding down on the screen then tapping analyze in the morning it wipes your data because it will only record one sleep cycle per day. I’ll continue to use for now but may try something else at a later date. ### 3/5 — Good program when it works *2019-09-19, version 3.2* I like this program, but get frustrated when info doesn’t sync to phone. I’ve hit wake up & data appears to come on watch, but if wait a couple of minutes to look at phone, it may not transfer. The best part for me is showing heart rate through the night since it has shown an exact time afib might have come on and/or quit. ### 2/5 — Not working *2019-07-19, version 3.11* Look good but is not working, I was expecting something better but In the last week I’m trying to Use it, but I got not success I hope the developer do something about, the app look good but is not working! ### 4/5 — Good *2019-06-17, version 3.11* Last week it wouldn’t track my sleep for 4 days in a row every morning when I hit analyze it crashed, when it works I love it, I only wish I didn’t have to tell it when I was going to bed and when I woke up. Sometimes I forget ### 4/5 — Awesome for the most part *2019-04-22, version 3.11* This app has crashed on me twice after tracking all night. When it happens, it doesn’t record the sleep. For a paid app, I expect more. Please update and repair. Otherwise I love this app and the data it provides! ### 1/5 — How use operate and configure *2019-01-09, version 3.11* Difficult to use and understand to setup The results are not know when woke up How to cancel the purchase? ### 3/5 — good but needs some work *2018-12-25, version 3.11* 2 main problems - it doesn't detect when i'm awake during the night unless i stand up and walk. i tried others sensibility setting but only get worse results. my old sport band can do a better detection when i'm awake during sleep time - from time to time, the app in the watch cannot read motion activity and the only option to continue is to cancel the session so all sleep data for that night is lost. 1 great feature is that you can press on the sleep bar graph and see exactly start and end times of each bar. ### 1/5 — Never assume anything when purchasing an app... *2018-12-02, version 3.11* I assumed that this app automatically tracked my sleep. Nope. You have to push a button every time before you fall asleep and it calculates it in the morning. Usually when you’re in bed, you’re... well... sleepy. I always forget to “Start” a session, which makes this app completely useless to me. Yeah the UI is pretty, but if it doesn’t do what I expect then it is a waste. Emailed the developers weeks ago to ask if this was the only way tracking could be done, and/or if they would be adding the feature in the future. No response. Deleted. Waste of my money. ### 1/5 — Only Crashes Every Few Weeks Now *2018-11-07, version 3.11* I’ve gotten a new watch, and the app is better - it only crashes and loses my sleep data every two weeks or so. If you can live with a sleep tracking app that does what it’s supposed to MOST of the time, this might be what you’re looking for. If you want one that works ALL the time, look elsewhere. ### 4/5 — Nice app *2018-10-14, version 3.11* Have been using this app for several months now. And not bad at all. Trying to get use the app still. Starting it when I go to sleep and the big thing for me is remembering to stop it when I wake up. Would be nice if it would allow you to edit the time asleep in case you forget to stop it. Was up and moving this morning and not the 1st time I’ve forgotten to stop the app and no way to edit my mistake. And I don’t have a normal life. And may only get 4 to 6 hours of sleep at one time. And then if I go to bed in the same day to get some sleep it recorded over what I’ve already had in sleep. Would be nice if it would show both periods of sleep in each event on the same day. Just a thought. For us people that are on call 24/7 and still like to keep up with our rest. Thanks for the app and trying to make it the best for everyone that you can. ### 4/5 — Tracking sleep *2018-10-08, version 3.07* It’s a great app and works amazing and it’s helping to get my sleep back on track. I do wish that the app would track my sleep without having to open the app on my watch. Sometimes I get tired and fall asleep and forget to turn on the app. Other than that it’s great! ### 1/5 — Bad experience *2018-09-08, version 3.07* I decided to give this app a chance mainly because I like to support new apps and I like the interface, unfortunately my faith was misplaced. The app crash when I try to open it on my watch, it also didn’t collect any data from my first night. Over all not worth my $3.99 investment. There are other apps cheaper with far higher rating. Don’t make my mistake! ### 1/5 — Not working *2018-06-22, version 3.07* Maybe I'm doing something wrong? Really haven't done anything. Tried to start it last night, it's reads I've been asleep for 25 hours. Autosleep still the best by far & is nowhere near as good as fitbit for sleep. Oura ring ordered. ### 1/5 — Push for sleep *2018-05-30, version 3.07* The app should recognize when you are sleep without you having to press it on Apple watch. This is an enormous drawback. ### 2/5 — Great.....at first *2018-05-04, version 3.07* I got this app two weeks ago and it was everything I was looking for in a sleep tracker. Then for the past three days, it refuses to sync up and record my sleep data. I’ve done everything support has said to do. It hasn’t worked and I am beyond frustrated that this is happening because I paid for this app. If I pay for something, I expect it to actually work. Disappointed. ### 3/5 — I’ve got all sleep trackers this one the best though *2018-03-25, version 3.07* It need ONE feature - PLEASE add motion over pulse line - so people can see whether pulse were jumping when people are still or turning or so . Please And maybe if not auto sleep then auto stop tracking in the morning ( and it ability to trim the sleeping time afterwards ) Thanks ### 1/5 — Meh *2018-03-23, version 3.07* I have to wear my Fitbit at night to track my sleep because this app is junk. I can’t seem to find any iOS apps for sleep that are worth anything. So sad. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2023-03-31* I have never left a review for an app - mostly because paid apps usually offer trial periods so you can determine if the app works for you. This one did not, but at $3.99 and with pretty good reviews, I thought I would give it a shot. Definitely the wrong choice. I purchased this app because it seemed on the surface like less work. I just want it to track my sleep without having to think about it. After the first night I went to my app to see my sleep data, only to find out you actually have to go in and press “sleep” for it to start working. I figured maybe I missed something, so pressed “sleep” the next night. Woke up the next day and went to my app to see my sleep data. Still wasn’t there. I finally noticed VERY tiny print I could not read without glasses and it said you have to press firmly to wake up. So I did. Then I was told that I had to go to settings>privacy>motion/fitness and allow sleep 3 access to motion. So I did - only to see that it hasn’t even asked for access. So how on earth do I fix that? I don’t have time to chase down answers, so I’ll eat the $3.99 and go find a better app. ### 1/5 — It no longer works *2023-01-08, version 3.2* It will no longer work and connect to my phone. ### 1/5 — When it works it’s great! *2022-09-09, version 3.2* If it downloads Not ac your sleep rhythms it works great! You can’t count on it! Paying for an app that works half the time is frustrating!! ### 1/5 — Does not automatically track sleep *2020-06-02, version 3.2* You have to actually push a start button on your watch after you get in bed. Unlike other apps or Fitbit, it does not automatically detect when you doze off. I’ll never remember to do this regularly so this app is completely worthless to me. Big waste of money. There are way better options, don’t waste your money on this old fashioned technology. ### 1/5 — App is not reliable, nor is tech support. *2020-01-24, version 3.2* When it works, it provides good information - when it works.... So far, I have had very little success with this program. It is a good concept, with decent data format, however it simply does not work. Sleep Tracker 3 has the following problems: frequently stops recording a few minutes into my sleep, sometimes records, but will not transfer the data to the phone, the data is recorded, but will not analyse. has a "motion processing error" and the tech support for this is non-existent. I have followed all of the FAQ/self-help steps to diagnose this and try to make it work, but so far my success rate is about 10%. Don't waste your money on this software. ### 1/5 — Not user friendly *2019-10-23, version 3.2* It’s not user friendly and I’m very disappointed about that. Why can’t it just sense when I sleep rather than me telling it I’m sleep and when I’m waking up. Won’t work on my iPhone watch like I expected. Doesn’t analyze. When I wake up it erases all of the data on the watch and doesn’t show anything on the app on my phone. I’ve ensured the motion and fitness is on but it’s not syncing with my iPhone or watch. I’ve uninstalled and reinstalled and the same thing. I’d like my money back. ### 1/5 — Terrible *2019-09-21, version 3.2* Why can’t it start and stop like other sleep automatically. Have to physically start and stop. ### 1/5 — Fail. *2019-09-10, version 3.11* Followed the instructions precisely, and the very first time using it the app crashed while analyzing the data in the morning leaving no trace of sleep data. How do I get a refund? ### 1/5 — Doesn’t work *2019-02-20, version 3.11* Awful!! Paid $7.99 for an app that doesn’t work. If I could give it no stars I would. Highly NOT recommend!!!!!!! ### 1/5 — Won't load on watch *2019-01-31, version 3.11* I purchased the three app bundle. They all loaded on my phone but none of them loaded on my watch. The apps on the phone say to launch the apps from the watch which is not possible because the apps won't load on the watch. I'd like my $7.99 back please. ## Most praised reviews (10 highest-rated) ### 5/5 — Most Data on your Sleep of current apps *2019-06-28, version 3.11* I’m going to give it 5 stars, although I’d like to select 4.5, because I can’t use the phone app to edit my start and stop times. There had been a LOT of time put in this app. I had used the previous versions on my old Gen1 Apple Watch, and they worked fairly well, but this version on Series 4 is *smooth*! I only wish there was a function to auto-STOP the tracking if it senses I’m up moving around for a length of time, or al me to edit my start and stop time via the phone app, or at least the stop time. There are many times that I’ve gotten up and been too tired or distracted to stop the tracker right as I wake, so I may get an extra 30-60 minutes that I can’t edit out. I’ve run this in conjunction with Sleep ++ and Sleepmatic, and they are decent, but THIS app is the most accurate and allows for modifying the sensitivity (most nights I move a lot when I sleep, so I can change that after the fact and reanalyze the night’s data). If it ever includes an auto-stop or an post-edit to select a wake time, this will get my full 5 star review. ### 5/5 — Love this app!! *2018-11-30, version 3.11* I just got an Apple Watch and wanted to monitor my sleeping patterns. This was is the best and I tried a few! ### 5/5 — Update 3.10 *2018-10-10, version 3.10* The apple watch 4 update to the app has changed the graphics. Now all I see are bars for my sleep graph, all of which are the exact same size. Previously you’d be shown thinner bars for small amounts of time and fatter bars for large amounts of time... now the graph shows one minute and one hour with the exact same sized bars. I’m not a fan of this graphic update, because now I can’t just glance at the graph and estimate in my head how long I spent in what phases and when. Now I have to run my finger over each and every bar just to see the differences I mentioned above. Overall, I love the app, and it’s worked perfectly for me other than one or two hiccups where it didn’t save my sleep data for one day or another. My only complaint is the loss of the varying-in-sizes bar graph. It’d be great to get that back again. **Developer response:** Thank you for leaving a review, this may be a bug in the recent update. Looking into possible fixes now. *Edit* Update has been released and the chart bars should be back to normal with relative widths. ### 5/5 — Amazing app *2017-12-29, version 3.03* This app was worth the wait! ### 5/5 — Great!!! *2017-12-25, version 3.03* Works great, would recommend it to anyone. ### 5/5 — Many Apps Good Movement Results Live heart best *2017-12-25, version 3.03* Tried a bunch of sleep apps for Apple Watch. Ehhh they all so so. I like this one the most as it's the best looking / most simple and actually provides real quantitative results. Just make sure you don’t leave the app while it analyzes for a couple of seconds each morning. One thing no other sleep tracker has is live use of the heart rate sensor. It actually takes your real live resting heart rate when you wake up. Which is great because I have been wanting to get a better heart rate and my doctor already said measuring it when I wake up was the best way. Thanks! ### 5/5 — No Snake Oil, Minor Inconveniences *2017-12-23, version 3.03* To begin I’ve used the apps that automatically “track” your sleep. And I couldn’t agree more with this developers claim that those apps are essentially snake oil lies. I’ve actually done minor research with sleep and though there is no perfect wearable sleep tracker this one is most on par with like a Fitbit. Yes you must start and stop your sleep with this app, though I believe the developers claims this is mandatory of watchOS and not the app missing out. Yes you must wait a few seconds for the app to process the data each morning. However you can rotate/lower your wrist while doing so and it’s over being you know it. What the results provide are better than all other options and best part is THEY ARE CLEAR TO READ. The iOS app is phenomenal compared to all the other apps in the design department. Also looking at the real motion data is great too. In conclusion I wrote a review as usually I don’t because PSA. Any app that doesn’t use motion to track your sleep is more of a lie from an app that does. The best sleep tracking uses brain waves. But motion and heart rate makes for a great combo too. Autosleep is just an autolie. Give this a try if you want detailed info on your sleep. ### 5/5 — Great app *2017-12-20, version 3.02* Awesome app, waaaaay better than my fitbit or any other tech piece, this app is a taste of the future! Thank you developer for having the best customer service of all time!! Sleeping like a baby~ ### 5/5 — Better than auto track apps, Updated Finally *2017-12-19, version 3.02* Best sleep tracker, have tried all of them for Apple Watch. The auto track ones are a fail and only use your heart rate. I have different sleep times too and auto sleep kept failing and I'd have to adjust the times anyways, nothing was automatic about them. I'd rather just have a better app track with motion. Then lame thing track with estimates of when I sleep or wake. ### 5/5 — Rocky start but stable now *2017-12-17, version 3.02* When first began using was fairly buggy. But now especially with latest version 3.0. It's working stellar. I'll update review if anything changes. Seems to be flawless working each morning and provides good data comparable to my old Fitbit and better than the auto sleep apps that just say when I sleep and finish sleeping. **Developer response:** Thank you for the review, Sleep Pulse will improve even more with updates, and additional features. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
