I’m using this app for a week and I love it. The only thing I would love to be able to connect this app with mi fit app. ??

It seems this app used to be simpler. Now it has more screens and fields and is always trying to get me to subscribe to the paid version, which just adds more info I don’t want to track. I have used it for a long time and will keep using it but wish I could roll back a few versions and hide a lot of the extra stuff.

I love this app. Does great job at tracking fasting/eating window. Love the functionality. I enjoy the challenges, coaching, and educational videos etc. This app is great, if it either had an integrated workout/meal tracking option, or if it integrated your data from other tracking apps, I would rate 5 stars. I want to know how workout types/intensity, as well as meals, coming into and out of fasting , effect things like ketosis.

This app was PERFECT when I first got it years ago. It is now unusable. It only saves my fasts half the time and my data is no longer even accurate. Very sad.

Excellent app but needs to sync with MyFitnessPal for intake analysis.

I really like how flexible it is, I usually start with a 16 hour fast but when I reach 16 hour and I feel good, the app lets me extend it another hour and another until before I know it, I’ve fasted 24 or more hours!! So far my best is 56 hours and the only reason I ended that was because I had an upcoming dinner engagement. If you’re fasting to lose weight you find it just melts off and you’ll actually feel much better, happier and healthier.

Use Simple fasting app instead, much much cheaper and it appears to actually work!!!

Well designed app but restriction to 168hrs is annoying and will switch to life app as a result.

Llevo mucho tiempo utilizando esta aplicación sin ningún tipo de problema pero lamentablemente en una de sus últimas actualizaciones arreglaron todo para asegurarse que antes de comenzar el Fasting haya que seleccionar (16,18,20 hrs ETC) varias veces- Back & Fw- antes de permitir un “comienzo real” Todo es propaganda. Solo buscan la incomodidad de la persona para que haga una, u otra cosa, o compras la aplicación (la cual es costosa) o terminas borrándola y buscando otra. Lamento tanto tener que dejar un Bad Review.
