So far so good.

I was looking for something simple and easy to use. This app has an additional plus point of being informative, so I know what my body is going through during the fast. The mood addition was a lovely surprise as it allows me to my unique mood patterns during fasting. I have a few suggestions: sometimes I end my fast but forget to press and on the app, an option to end it and then confirm how many hours I actually did. Secondly, if I delete and re-download the app I lose my previous stats.

Worth it

I’ve only used this app for a day, but so far I enjoy the features. I like that it shows you milestones you’re hitting and what happens during the time you are fasting. It keeps me motivated and that is something I definitely need to keep this fast going.

One thing I had a little trouble with was setting up the amount of time I was going to be fasting for. I had already started fasting a few hours prior, so I selected that option and tried to set it to the correct time, but it is still a few hours off. The menu to choose from in setting the time was grayed out and I couldn’t really see what I was selecting. Otherwise, I haven’t run into any other issues and I am excited to see if I can reach my goal.

Long term fasting

I was looking for an app that would allow me to determine the length of the fast I plan. This app is great for that. I like the set up for determining how to begin and how to end with great information on how to do both. You can also determine for yourself the length of the pre and post fast periods. The only feature I would like to see are inputs for glucose and keytone readings, although I may not have drilled down enough in the app to find out. It wouldn’t surprise me if they were there. Anyway, great app! :-)
