Great app, surprisingly high storage use

I've been using this app pretty regularly for about a decade. I like its curve graph better than other apps I've tried. Downside: it currently takes 7GB of space on my phone, and there doesn't seem to be a good alternative to using that space (the export option's email doesn't reach my inbox, and the backup option maxes out at 100 records). That's without any sound recordings, just the sleep data. I'd expect something much smaller, even with a couple thousand records. Nonetheless, great app.

No easy way to bulk delete old entries

I have been using this app since 2014 (yes, seriously). I love it. But it has so much data now that it doesn’t seem to be working as well, I will occasionally swipe over to end a session and the session just won’t be there. But it’s also taking up a ton of space on my phone at this point. While you can get to a specific date pretty easily, as soon as you hit delete it takes you back to today…if it would at least go to the next or previous day, I could manage to slow delete more easily. But it would also be great if there was an option to delete between certain dates.I am close to deleting the app and restarting, but I would like to keep the past year.

Privacy-loving, one-time paying, feature-packed

I literally sought THE ONE SLEEPING APP that would not charge me rent for having it work on my phone. I paid for Sleep Meister and it was worth it.Thanks, app developers, for not using a subscription model.I also was pleasantly pleased to find that my data remains private. Their terms of service are simple. THANK YOU, DEVELOPERS, FOR A SIMPLE TOS.Apart from those answers to the fundamental question “How does this app work?”, there’s the classic “What does this app do?” I like many things of this app. I can record my sleep talk, I can change the sensitivity with which recordings start, I can learn my sleep onset latency (super useful to calculate sleep schedules), I can choose to sleep for 8 hours or to wake up at a given time, and most importantly, I can see a personal hypnogram and I can wake up at the best time possible based on that!This small app studio created software that works well. It also does its work ethically.

Daylight savings bug

Just observed bug today: alarm does not sound during transition to daylight savings time. I had alarm set to "time selection". The alarm was set to 6 AM. It did not go off. Thankfully I had a real alarm clock set as a backup. I wonder if this would have gone of an hour late (7 am). Also: feature request - Please add ability in your app to manually adjust entries. I know the "sleep onset time" is wrong sometimes. Sensor wrongly believed it took a long time for me to fall asleep. It is rare, but does happen. That error affects Apple Health stats. ====Original review:There are plenty of apps in this category, and I've tried most of them. This app has a combination of features found nowhere else. The backup alarm is clever and important. The audio recording is a great feature too. I appreciate the latest new feature of visualizing the recorded audio.
