Great App

Okay, I’m going to start off by saying that I love the app. It works wonderfully, and the technology seems to be greatly engineered to check when I really am sleeping and when I wake up. The audio recordings are great, they’ve caught me saying some hilarious things in my sleep.
I do have some suggestions. I understand that the feature where you can either shake the phone or hold the button for three seconds are meant to make sure people are really awake and getting up. Well, I happen to be a pretty light sleeper, and I get up very well, and I own the full version of the app but I’ve noticed that there is no option to just tap to disable the alarm. I’d like this feature to be implemented if it’s not too much to ask.
Also, I think it may be cool to have a dream journal added. Like when you wake up, there may be a notepad there for you to begin typing out what you dreamt, and it keeps track of the night you dreamt it and stores it somewhere. There should also be an option to click a button that says, “I don’t remember what I dreamt.” And to go back and begin a journal entry if you didn’t remember it at first but now do/didn’t have the time to type it then.
Thank you for your time!

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.)

Developer Response ,

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: .

I never have never seen such a good app.

There are many good sleep tracking app for the Apple Watch. But I have never seen such a good one. Why? Well, before I get the Pillow app, I was using the auto sleep app for the Apple Watch, and at first I loved it! After a while though I started recognizing that it was a little in accurate. After using the Pillow app, I’ve seen how my sleep is in as good as I thought it was, and I feel like I can make it better If I continuously use the app. I had if I get below a 70% sleep quality score, that I will not have a good day or I will be tired, but if I get above a 70% sleep score, then I know I can’t have a great day.

Another reason why this app is better than the app I was using before is because it is so much more in depth. Before I even used the Apple Watch, I had a fit bit ionic, and I loved the sleep tracking feature, because it was so accurate and it was very in depth, but this is an Apple Watch and it’s not even made to be a complete fitness device, and the fact that it has more in-depth tracking and more accurate tracking than the Fitbit, just shows how great an app this is.
