This is very nice: simple to use, big and easy buttons to start and stop the timer; enough info to keep track of fasting length. Lots more info available if you choose to go Pro. And no ads. 😁

No frills app to track my fasts and my weight. It gives me what I want. It was a bit tricky to figure out how to log my weight (use the "+" in the upper right, then "Log weight manually" in the pop-up box). Also, oddly, when I first tried to install it, I got a message that said it wasn't compatible with my phone's OS. But then the next day, it was there. (I bought the paid version to support the developers, since it's so inexpensive. Don't know what's different about it vs. the free version.)

Despite some minor grievances (like the fact that it won't let you adjust the minutes upwards to reach :00 because the intermittent values would lie in the future, and that fasts longer than 24hrs aren't represented accurately in the calendar), this is far and away the best, no-nonsense fasting app. And I've tried them all.

What’s new

Minimal hotfix release: avoids an IllegalFieldValueException crash when selecting a nonexistent spring-forward DST time in the Change Start Time dialog.
