I like the app despite its inaccuracies

I like this app and find that it is helpful with my current goal of trying to get more sleep so I can be more clear and productive every day. I purchased the Premium version because I wanted to hear what noises I could possibly be making at night. The sound recording seems to work only intermittently, despite the fact that the phone is about a foot from my head and the mic sensitivity is on high. It also will sometimes record several notes a minute, for about 10-15 minutes, and those notes end up being empty when I've gone to listen. Also, despite the fact that in my "notes" I put "read" almost every night and "ate late" only once or twice, it says that I ate late about 36% of the time and read 11% of the time - even after I went in and put "read" on almost every night to see if it had an affect - that part of the app does not work. Also, the sleep aid music worked before I paid for the app when I was going to sleep. Now if only works when I'm not using my watch. It does work for naps on my watch, just not when I'm going to bed at night. (I do wonder how it can tell the differences between light, deep and REM sleep.)

Hello! Thank you for reaching out. We're really glad you enjoy Pillow. Regarding the audio recordings, please note that Pillow cannot record any audio while a sleep aid is playing either from Pillow or another app and this could explain why sometimes you are not getting any audio recordings. If you believe that's not the case, please contact our support team to investigate further. Also, the percentage value in the sleep notes indicates how much your sleep quality was affected, not the frequency of each note. Regarding the sleep-aid music, it should always play regardless of whether you use the Apple Watch. Can you please contact our support team and let us know more about this issue? Lastly, to learn more about how Pillow's sleep analysis algorithm works, please check an article that we posted about this on our blog on the following link: .

Great until it wasn’t

When I first got this app it was great. I was so happy to find a sleep tracking app that worked with Apple Watch and didn’t force you to pay just to track your sleep. The automatic sleep detection was absolutely awesome. I loved the interface. It was annoying how you had to buy the premium version to see your past sleep data, but not a deal breaker. But then one day the automatic sleep detection stopped working. I would wake up and eagerly check the Pillow app only to see that it didn’t collect any data. I thought it might be a problem with my Apple Watch so I went through all of the steps to make sure it was detecting my heart rate, had permission to collect data, etc. none of that worked. I turned off automatic sleep detection mode and put it to manual. And it worked! But as I was checking my sleep data in the morning I got a low battery alert on my phone. My phone that had been at 100% 7 hours before was now at 14% without me using it. I also quit all of my apps before going to bed. This also happened the next few nights I used manual mode. I can’t help but to think that that is the cause of the power drain. I don’t have a place to plug my phone in overnight where my phone can still be in range of my watch, so this is a problem for me. I’m going to try turning automatic sleep detection back on tonight to see if it detects anything/if it was just a glitch. Aside from that, the app is really great and I would really like to keep using it.

Hello! When you use Pillow with your iPhone, Pillow performs processor-intensive tasks that consume battery. To avoid any inconvenience we recommend that you keep your device on the charger during the night. Pillow on the Apple Watch consumes 0% battery if you have enabled "Automatic" mode or if you have selected "Sleep cycles" only. Please note, however, that if you are using WatchOS 5.x or older, the Apple Watch Pillow has an optional feature that can wake you up using haptic feedback (vibrations). To achieve that, Pillow uses a background audio mode (no audio is recorded if you have disabled audio recordings) that can consume a significant amount of battery . If you disable that feature then Pillow on the Apple Watch will consume almost 0% of the battery. To disable alarms with Apple Watch Haptics: Open Pillow on the Apple Watch > Scroll to the bottom > Tap on “Settings“ > De-select ‘Apple Watch Haptics’. Furthermore, if you have gone through all the suggested solutions on the following article and the issue persists, please contact our support team to assist you further: .

Love it so far!

I’ve only been using this with my Apple Watch for a couple weeks now so I’m still learning. I can’t remember what I didn’t have before I upgraded but I feel like the free version was quite basic. I’ve never paid for an app upfront and it was pricey but well worth it.
My only issue (although I thing this is my body and terrible sleep patterns rather than the app itself) is that for a few days, the alarm would go off early, while I was in a light sleep mode, and I’d wake up feeling so refreshed. Since then though, it doesn’t go off until the exact alarm time and the analysis shows I’d been in rem sleep for an hour prior to my alarm. So I’m not as refreshed and then just keep hitting snooze. (The snooze times are a whole different issue that I don’t understand but I shouldn’t snooze anyways so that’s on me!)
If I’m in rem cycle during that 30 minute window, obviously my watch vibration won’t go off until the actual alarm time but I would love an option to set a specific time range that it can wake me earlier instead of just 30 minutes. If I could wake up better at 5:15 than I would at 7, I’d be great with waking up much earlier.
This may be an option I just haven’t found yet but if it isn’t, that would be an awesome addition to a future update.
Love this app!
