Working (restart watch)

TL;DR - restart phone AND watch if you have any issues. In-App is quite expensive and feel I paid for features I don’t use. Would prefer if the functionality was split between a few cheaper options.

Updated Full Review: Initially had trouble getting app to work on watch - everything looked ok but was unable to launch sleep recording as the button on watch face was non-responsive. Did finally get it to launch once, but after that it just kept crashing.
Did the usual: uninstalled app, restarted Bluetooth, restarted phone, reinstalled app. Nothing changed - app just would not work. Gave up and posted poor review in frustration.
Next day had issues on watch (an activity tracker crashed multiple times during two separate activities). Restarted watch, issue with tracker was resolved.
Decided to retry this app (partly because dev responded to my review/rant and partly figure it might have just be a bad coincidence).
Happy to report app now appears to be functioning correctly.
Having used the app with In-App purchase for a couple of weeks I’ll say it works well for the most part. The interface is clean and intuitive and has very good integration with Apple’s Health App. With that said I would prefer if the In-App purchase (which is comparatively expensive) was split across, say, 3 different sections. I don’t use the alarm, or the nap feature and haven’t had much luck with the audio recording. All I really want is to be able to look at historic data.

Hello! We’re sorry you are experiencing problems with Pillow. The easiest and most reliable way to use Pillow on your Apple Watch is to start you sleep session from the Apple Watch: To do that make sure both devices are in range and can communicate via Bluetooth > Open Pillow on both devices at the same time and tap “Start” on Pillow on the Apple Watch (Do not press Start on the iPhone) >Scroll down and tap “Next”. If you are still experiencing problems please contact our support team to help you.

What can I have ,

New update not accurate at all

Since the newest update, this app does not detect if I wake up during the night even when I get up out of bed. Last night I lay awake for at least a half hour, got out of bed as well during this time and it was not noted in the data. I also got out of be x2 more times and that wasn’t recorded either. In fact my sleep quality was supposed to be good and it wasn’t at all. Very disturbed night!
Edit 1: Despite repeatedly retraining this app AI it is not detecting how often I am awake. I would have thought my heart rate increase would align with waking too but not on the apps graph. I am using Apple Watch 3 also. I am about to give up on this app. I am using the paid upgrade too. Even audio has me talking to someone and the app says I’m asleep. Totally useless. When are you going to fix this?????
Edit2 : new update allows user to have app reassess and increase awake time. I had to do this 3 times after last nights session before looking vaguely accurate. Still didn’t take into account that it took double the the time to get to sleep. Still doesn’t line up with increase in heart rate even when I got out of bed.
More work to do. I am almost ready to delete it.

From the description of the issue, it seems that the permissions required by Pillow haven't been properly setup but this can be easily resolved. Please advise the following article with solutions and recommendations and let us know if the problem persists

Not that intuitive to use

Frustrating. Using the App on the phone together with the iphone as well is not easy. In this day & age that’s just not good enough.

Specifically, starting the App on the watch it prompts you to open both the app on the watch & the iPhone together (but only in their response to an adverse review do they mention NOT to actually hit start onthe App on the iPhone). A small but important detail that had me bouncing between the two with the Watch sending me to open Pillow on the iPhone and then next asking me did I want to end the session on the iPhone!!! Be better if they made it more obvious what they meant rather than finding this important point in a response to a poor review.

The other annoying feature is as you try to look at historic data their advertising screen pops up telling you to spend approx $7 to upgrade to the premium version and it covers up your data. You can look at the most recent data but not the older data. That’s an annoying & shabby trick to force you to buy. I happily buy Apps where I see benefit. They need to figure out a better solution that doesn’t antagonize their users. Who wants to buy an App to stop it annoying the hell out of you. I won’t on principle.

Hello! Pillow requires the use of the iPhone only if you want alarms and audio recordings since those two functionalities are not currently possible with the Apple Watch only. Hopefully, upcoming versions of watchOS will allow us to simplify things. It's also worth mentioning that we're working on automatic sleep tracking and detection for sleep tracking and analysis (alarms and audio recordings will still require manual interaction). Ever since we decided to make Pillow we wanted to find a way to allow as many people as possible benefit from the advantages of sleep tracking without sacrificing quality or privacy and at the same time make it a viable option for our small company that continues to work on bringing new features and capabilities. That is why we decided to provide a set of basic features for free and an option to upgrade if you decide later. That said, we are working on ways to offer a free trial so that you can experience Pillow's full potential.
