I’m new the fasting, but I’ve used this to track my two fasts and found it very easy to use, I’ve even managed to get my wife to use it. Outside of the app one thing that I thoroughly am impressed with is the response you get back from the developer. He’s still designing the app as well as adding elements that people using the app for asking for. This will very quickly become my one and only fasting app. ### 5/5 — Easy to use. *2025-10-26* Really like the design of this app. It took me a couple of seconds to get used to how you set or adjust the time, but once I figured it out, I really like it!
