Pillow is stuffed with ways to improve your sleep. The app tracks your z’s, records your moods, and follows your daily routine to help you establish a consistent sleep pattern, night after night. We love the app’s intersection of sleep and data. Tell Pillow about your daily routine—including your mood, meal times, and amount of caffeine you’ve consumed—and it’ll begin to learn what’s helping and hindering you at night.

Not merely how well you sleep and how it can vary according to factors you can record at bedtime. Also wether you snore or talk in your sleep, and what you say. The graphs plotting "sleep quality" versus "weight" are clinically significant only if you have weight-induced sleep problems, likely if your BMI is 35 or more. For the comparison to heart rate, an iWatch is best, since it monitors your wrist pulsations continuously and allows the app to compare it to the movement and audio data it monitors while under your pillow. This will expose a side of you that you knew nothing about, fascinating in itself, and may warn you of upcoming or ongoing health problems. A truly useful app. It is one of the first things I look at EVERY morning! It also provides detailed info on how your behaved during the night, indispensable for persons with rate or thutm problems. 🤜 With the “iWatch” the amount of info generated is fascinating, but …. When you don’t wear the watch you get nothing, whereas when I did not have the iWatch the app would monitor my sleep (but not heart) with the iPhone under the pillow. The problem seems to be that when I forget to put the Watch on after charging the battery, I also forget to put the iPhone under the pillow. I’ll work on that for a future update of this review. ¡Great app! Don’t go to sleep without it😂 Problem solved: now I have two Apple watches and there is always one fully charged.

Just what I need

I’ve been using the app for a couple years now, but it has definitely helped more recently with the new job I started about 6 months ago. I work 7 on 7 off overnights, so I change from day sleeping to night sleeping every week. This app is a godsend for not only helping me track my sleep, but also helps me wake up in a sleep phase that allows me to feel more rested. I love that I can set an alarm and it’ll calculate on screen how much sleep time I’ll get based on the current time (because I’m tired and one less thing to calculate is more helpful than I could’ve imagined) and it lets you pick a window of time so it can try to wake you at that ideal sleep phase. The other thing I love is that not only can you set an alarm for a timeframe, but you can also set one for duration of sleep. When I’m transitioning back to night sleep, I get off in the morning and need to only sleep a few hours or I won’t be able to sleep that night. So I can make an alarm for X hours and it’ll wake me when I’ve actually slept that amount of time not just X hours after hitting start (great for catnaps too so it doesn’t start counting time until you fall asleep). Honestly, I don’t use all the features the app has to offer, but just the little I do is all I need. The only thing that I don’t love is not being able to just start the alarm on my watch without also needing the phone app open, but I always have my phone charging by my bed anyway so not a huge deal I just forget sometimes and it’ll error on my watch until I open my phone. I definitely recommend trying this app!

Hi! Thank you so much for your kind and detailed feedback! 🌙💜We’re so glad to hear that Pillow has been helping you manage your rotating overnight schedule and improve your rest, that’s exactly what we aim for.By the way, it’s actually possible to use Pillow solely on your Apple Watch without opening the iPhone app, as long as you choose a preset that doesn’t require iPhone features like the sleep aid or audio recordings. If you’d like more details, feel free to reach out to us through the Helpdesk in Pillow’s settings, we’ll be happy to guide you!

One of the main things I use my Apple Watch for is to track my sleep. I’ve definitely noticed some helpful patterns over the past year. I tend to over sleep (takes about 9 hours for my body to feel rested and want to get up on it’s own). Could mostly be an antidepressant medication side effect or lack of exercise lately, but I’ve always been a sleepy head). Using the Pillow app, I can see that when I have to force myself to get up after only 7 hours, the quality of sleep is overall way better (barring any nightly disturbances such as noisy neighbors and the like). In the hours that I oversleep, I don’t get any deep sleep and minimal REM, so it really doesn’t provide much benefit.Knowing that I should try to limit oversleeping, Pillow has even made forcing myself to get up a lot better! Being able to set an alarm and have the app wake me up before the time I set based on what stage of the sleep cycle I’m in has made it so much easier for me to get up and not want to hit snooze (e.g if it senses I will be in a deep sleep at the set time for the alarm, it will wake me up a little beforehand when I’m only in a light sleep so I don’t feel groggy). I’m also thankful for having an alarm that is just a gentle buzz on my wrist….SO much more pleasant than having a noise blaring in my phone and having to find and silence it! All-in-all, I’ve just never been great at waking up. I am not a morning person in the least and have always been envious of people that are — people that just get up and go. I’ll never be that, but I feel like Pillow was made for people like me. A huge thank you to the developers!! I love this app. 💜🙌🤍💜🤍🙏💜
