Not worth the upgrade
This app may be the most complete you can find for IF, but unfortunately it suffers from poor organization and planning out. Its frankly a mess that needs a lot of improvement. Its layout is sloppy, its structure doesnt make it easy to track fasts lasting across two days (it counts them as two fasts rather than one). It has poor visualization of progress. The free version has incredibly annoying pop up ads that play games with trying to trick you on closing them. The paid upgrade adds very little value. Only letting you set a goal weight and get rid of ads. There are many other things that are wrong with this app. It needs a complete rewrite. Until then, not worth the trouble.
