AWESOME APP! Just started using the app today

UPDATE: I am 12 hrs into my first fast. The review I left earlier is below and well worth the ability to access more of the features available on this app. The text updates on the effects of my fasting time have been a HUGE motivation! And knowing how the fast is affecting my body only increases my will to reach the next level. 5 stars and I have a feeling I will be paying for membership soon! Thanks

Original review: 1 hr in and I wanted to use the app longer before rating to be fair, but the developers built in a block to some functions unless you write an honest review. Honestly, it seems helpful but since I have only been using it or less than two hours, I can’t give it more than a “meets what was stated on app description” three stars. I hope to update this after I have been on it and can access more of the functions. But so far (2 hrs in and trying to explore the app which requires this review to do so) it’s keeping track of my time on my fast accurately. Developers, allow the free functions without a review so we can honestly review your product. I hate leaving less than 5 stars but I can’t access your program with out this write up. Thanks and look forward to leaving a better review when I can honestly use the app

Testing Fasting App Phase

Have lost a significant amount of weight in recent years. Most significantly since July of 2021, prior to discovering this longer term fasting app. Haven’t seriously restarted my Keto regimen yet. Today, I’m restarted at the daily and or one day Fast for a couple of weeks. I plan on slowly titrating up to longer durations; most likely OMAD as a steady and consistent plan over the long haul. Believing this App will provide the basis tools for monitoring. After all is said and done, consistency rules in conjunction with intermittent fasting. In addition to random OMAD I’ll do 18-6 as my standard daily eating plan. Ultimately, looking forward to using your App. Bill D

Informative, bit clunky

I downloaded this so I could join my sister in fasting for health, and I really do like all the information provided (hidden behind vaguely translucent “rate to unlock” bubbles you can read through if you’ve got the patience, which I no longer have). I can keep track of how long I’ve been fasting (this is where it gets clunky, more below), and see where in the fasting cycle I’m at. It’s still all Greek to me at the moment, but I’m learning more every day.
As for the ability to log a fast that’s already started... I wish there was a way to adjust the time as well as the day you started, because I was already a solid 14 hours into my fast and backtracking a day added 24... With no way to edit. So to keep my information honest and accurate, I ended up uninstalling the app and info completely and then redownloading and backtracking my fast start 24 hours later. A bit excessive and annoying, just so I can see where in the cycle I'm at. This clunky UI (along with the bizarre white on light gray background roller bar and non-existent past days for setting existing fasts) is the reason I only rate this app four stars, because despite the plethora of information, one has to extrapolate and bend their brain a bit more than strictly necessary to navigate and utilize the app.
