User reviews

Nice! Fix weight tracker please.

I tried to contact for a bug report but could not find where to do it.

I accidentally entered the wrong weight by 100 lbs, so the graph is way off, even after immediately putting in the correct weight. What was odd is that it put the correct weight difference from days ago, but my graph is goofed with no way to edit. Also it dos not seem to update to Apple health with that turned on.

When ending the fast, after I met my goal, don’t pressure me to keep fasting.

Thanks.
