Good but audio has stopped working?

All seems fairly accurate and I like the interface, although there seems to be a glitch over the last week or so - the audio has stopped working, I haven’t changed the settings at all but every night there are no recordings of sound which can’t be right. It was working fine before. Also when you flick back through the days, it seems to add in extra entries for some days with no data which then get counted as the ‘worst session’. I’m not sure if it’s a new update that has brought in these glitches? I think it also would be good if you view a summary of every day over the last month (a bit like in the activity app where you can view a whole month’s worth of rings on one page) with the daily percentage or number of hours sleep, but not in a bar chart like when you rotate it.

I’d also like to know more about how it judges the quality of sleep - some nights I’ll have over 8 hours, with a good mix of light, deep and REM sleep but the percentage will be lower than I’d expect.

Still though, a good app that I enjoy using every night. I hope the glitches get ironed out.

It’s ok but finding automatic very inaccurate

I have recently moved from a Fitbit to the Apple watch and was looking for a sleep tracker to mirror the functions of my Fitbit.

I Initially liked this a lot but recently it’s become only partially accurate. I use it in automatic mode with my S3 watch and it tracks my evening time of dropping off pretty well. However, it no longer tracks any daytime naps (the other day I took a friend to the airport, so had 3 hours sleep at nighttime and then four hours later in the day. None of those 4 hours were tracked). It also tracks me as being awake the minute I first wake up in the morning. I have young children - I’m often woken up at 5am and go back to bed for 2.5 hours. That extra sleep past my initial waking point is never registered - it’s like it’s decided I’m up, so I’m up. But these inaccuracies are making my long term data completely inaccurate.

The button to reanalyse sleep seems to have disappeared too. I love the interface and the idea of the app. It just doesn’t perform as reliably as I need it to.

Hello! If Pillow doesn't detect naps, please make sure that 24hour detection is activated. To do so:1) Open the app's settings, 2) Tap on the automatic "Setup Wizard", 3) Tap "next" in the first screen asking you to enable automatic mode, 4) In the "Exclude time" screen that follows, please set the "24hours detection" switch to the "on" position, 5) Complete the rest of the wizard. Regarding the sleep analysis issues, it seems that Pillow hasn't fully adjusted to your patterns. We recommend that you continue the training of Pillow A.I. as follows: Open Pillow on your iPhone > Tap on the Settings icon on the bottom left corner > Go to "Pillow A.I." > Reset Training. Pillow will ask for your feedback and give you the option to re-analyze your sleep sessions so that future analyses will be as accurate as possible. Please contact our support team if you require further assistance. To contact support: Open Pillow on your iPhone → Tap on the Settings icon → Select ‘Helpdesk’.

New algorithm and options are an improvement

It’s only been a couple of days since the new algorithm has been introduced but so far so good. I like that finally I can do some sort of editing, although the ability to edit sections of the sleep patterns would be even better. The accuracy seems to have improved with the new algorithm (I use an Apple Watch), and possibly the ‘training’ option is helping with this. The analysis is almost instantaneous now so I haven’t had any errors. For a while I’ve been using Pillow alongside another app which offers auto sleep detection, but I’ve always preferred the alarm/audio options, feedback and layout of Pillow; so if and when AutoSleep detection is introduced I’ll definitely consider using Pillow as my default option in the Apple Health source data order. Overall I’m very impressed with this version.
