### 3/5 — PLEASE FIX YOUR BUGS!!!!

*2025-01-08*

It’s soooo frustrating trying to use the app to have it constantly freeze. For the love of god….please fix it!

It would also be nice to have minerals included in the nutrition tracker as well as a water tracker.

### 2/5 — Crashes iPhone 11 Pro on iOS 17

*2023-09-28*

After launching this my phone slows to a crawl and becomes totally unresponsive. If the Lock Screen comes up it’s all over. There’s no getting it working again without 10+ minutes of painful force quitting and rebooting and over again.

Update:
I believe the issue is related to having the Apple Watch connected. (1) a couple of weeks ago I noticed the heart rate on the watch would not be reflected in the app unless I raised my wrist to view the heart rate. (2) today after it crashed my phone, the watch app kept running on its own. Eventually I switched to Fitness App even though my watch was still running the workout and force quit peak fitness. A few reboots and force quits later, I finally had a working phone again. I had also, by now, closed the app on the watch. In retrospect, that may have been the reason my phone became usable again.
