Simple is Best! What I enjoy about this app is that it's lightweight, works offline, and displays pertinent information that doesn't require navigation. I don't desire anything to be improved, nor any features added. I like how simple it is to add weigh-ins from the journal tab too. I honestly love the dark mode colors -very synthwave- thanks dev(s)! In addition, I enjoy the privacy of this app.

I bought the paid version and am very happy with this app in general. It has detailed stats and a smooth minimalistic interface. The only flaw is the basal metabolic rate graph. It's completely messed up. I don't know if this is a problem solely with the graph or extends to the actual calculation. I strongly suspect the former. Having tried several of the other top fasting apps, I still highly recommend this app.

I have been using this for about half a month now, and it has definitely helped me. I tried fasting before, but for some reason pushing the button helps, and I liked the tracked data. Seeing the weight loss graphed was pretty helpful. Knocking off a star because all that data that I like has disappeared for some reason, and I don't see any way to get it back. My preferences and identity info is still there, but the weight and fasting history is just gone. I don't really need it, but it was nice to have.

What's new

Fixed a bug that caused date ranges on the journal tab to be stuck, causing confusion as to why entries/fasts wouldn't show up.
Other miscellaneous bug fixes and visual updates.
