Cant click on “best” mood

ErikErnest on

I use iPhone 14 pro ios 16.6 with Zoom view mode. When I want to log my mood, I can’t touch the smily face in the right that indicates the best mood.

Worse design, still lags sometimes

BitterMint 21 on

Great app, loved old design more, it seemed smoother and calmer, don’t love the contrasts of the current one. Apple health data doesn’t sync properly, and text on the fasting circle overruns into the circle. But thanks overall. The best one for fasting out there.

Recent update is a mess

constantine232425 on

Purchased the subscription to track my fasting. Not nutrition, not activity, not sleep. Fasting. Recent update made the application unusable for me - I don’t need that calendar mess with no data. I want to see my fasting calendar under the “Me“ tab again. And nothing more.

best

muramour on

best app for fasting, tried plenty apps but they are so annoying

Best app to fast with

nothing like Messenger on

Great simple app design. I mainly use the app as a fasting clock/reminder and sometimes I like to scroll through my monthly summary. Too bad they have recently removed monthly stats from the free version. I don’t use sophisticated features like coach, calories/sleep/activity count so paying $70/year for a fasting calendar is too much in my case. Please consider creating more affordable plan to enable monthly stats.

Like it!

It’s really help to control yourself! Recommend!

Quick note

notprivate on

I think you should add the editing of real hours fasted. Didn’t find such feature. As sometimes you just forget to stop the clock and prolonged hours aren’t real and fair. So ability to quick edit and bump then down would be helpful. Thank you, overall pleasant experience.
