I love the fact that it shows the status of my fast on the lock screen. I’m always looking at my phone, so when I see how far I am in the fast on the lock screen all the time it keeps me motivated to keep going. It’s simple and easy to use, and I love that it integrates health data like workouts from the health app on my IPhone. I bought the lifetime/one time payment of $63 (as of June 2026) and so far I consider it to be a great investment in my health. The notifications telling you what part of your fast you’ve reached is also a nice feature. I just wish there was an option to input height using feet & inches and weight using lbs, but otherwise it’s a solid app!
Thank you for the thoughtful review, and for picking up the one-time purchase. That kind of support really helps as a solo developer. Glad the lock screen status, Apple Health sync, and fasting stage notifications are working well for you. Good news on the units: weight is already switchable to lbs in Settings (it follows your iPhone's region by default). Not sure what you mean about height though, Fasty doesn't have a height field at all right now. Feel free to email me at kai@amicu.app and explain what you're picturing. Best, Kai
