not writing anything to the Health app

It looks like Smart Alarm Clock for Watch is not writing anything to the Health app. I’ve used it for 2 nights now, and it’s waking me up as expected, but shouldn’t it be submitting data to the Health app? All permissions appear to be on as well as “background app refresh”. I do use “do not disturb” and “theater” modes on my Watch when sleeping, but that seems to be almost standard. Is it not supposed to write any data?

Thanks for the feedback. It’s not a sleep tracking app. We might add sleep tracking capability to the next version

Alarm clock for my watch

So happy I found a smart alarm for my watch, I have searched a long time ever since I got my Apple Watch, this seems to be the only one that works. I do not understand why Apple does not have this built in, the watch is on your wrist, so it is perfectly suited to track your sleep stages, and wake you up when it needs to. Other wearable devices seem all have this capability, but not Apple Watch. Enough complaints about Apple Watch, let me tell you about this app. It has a super simple design: it only does two thing, bedtime alert and natural sleep cycle alarm. I like the bedtime alert, it keeps you in a regular schedule, but there is nothing earth shattering about it, except it makes it really easy to set up the alarm. If you answer the bedtime alert from watch, you can one tap set the alarm. Regarding the alarm, you specify a 30 minutes window, and the watch picks a good time to wake up when you are sort of awake. This works great, I especially like the gentle vibration instead of a loud sound, it makes waking up so much more pleasant. It seems the phone has to be nearby for this to work, so that is a caveat, but other than that, no complaints from me. Glad I got the app.

I’ve used it two days, won’t use it a third.

I’ve used this app for the last two days. I will NOT be using it a third day. It’s supposed to wake you in your lightest sleep cycle. Both days it has woken me in the middle of a dream (the hardest time to wake). I had no idea it was going to talk when I set and turned off the alarm, disturbing others around me. This morning I was awoken not by the alarm, but by someone telling me to answer my phone. The alarm went off on my phone, even thought it was less than three feet from my watch. Once I turned it off, my watch started going off every five minutes continuing to disturb a dream, causing the app that tracks my sleep to say I was awake when I was actually asleep. I’m not sure what this app is supposed to do, but it’s not doing it for me. It’s not silent. It doesn’t wake me in the lightest sleep, but the deepest. There is no reason for me to keep using this app. The last two days have been the worst mornings I’ve had since I was an over trained teenager. I’m done. I’m just sorry I spent money on this madness. There are so many other places that money could have gone where it actually would have been useful.

Please upgrade to WatchOS6 and download version 2.0.0. Previously we have to do a work around in our app to support smart alarm but WatchOS6 has now open the limitation.
