Estevan E. (47 years old)

I started to fast this past week, the first 2 days were for 19 hours, and on the 3rd day for 20 hours. I was exited and knew the outcome like feeling a little frustrated, feeling hunger pains and a slight tension on the back of my neck when ketosis kicks in. I was on the 4th day of fasting, but what amazed me is that I work out every morning with my wife before work and I was getting bursts of more energy and endurance thinking that I was going to feel weaker but I didn’t. I also had a euphoric feeling all day, I told my wife, out of no where going to work, I feeling really happy. I was good for 22 hours with out any frustration, hunger pains, and no tension behind my neck. I would recommend this Life Fasting App to people who want to have a healthier body and longevity in life.

Pretty good, but could be awesome

I just started fasting a few weeks ago and wanted an app to track my fasting time. I decided I’d rather use an app that mainly allows me to watch my fasting time GROW than to watch my eating window SHRINK, so I chose this Life app. Overall I like it for all the reasons others have noted. I especially love that it shows when you’re body is supposedly in Ketosis. A few things that I think could make it truly awesome:
First and foremost: Make this app compatible with the Apple Watch! Honestly, this alone may cause me to switch to another fasting app. Sad face.
Allow users to enter their weight data with a decimal point. Currently you can only enter whole numbers. Everyone knows that those decimal points count A LOT for people looking for trends mapping results. Seems like it would be such a simple programming fix and would allow much more accuracy for users.
Show the user’s actual eating window for each fasting day. In other words, after the user has tracked his/her fast, calculate for them the resulting eating window (times) and number of eating hours. Again, seems like a pretty easy “fix” that would make the app more robust and improve user experience.

Basic Fast Tracking App

Been fasting every day for the past five years. At the beginning of this year I started working out again, so I wanted to become more disciplined in my fasting. For me personally, this app is great for that, and I can see how it would help others push past their goals (as they see they only have an hour left to go). But the health features are lacking to almost non-existent.

It reflects at which point the body goes into ketosis, and heavy ketosis, but lacks any relevant data input to do any real calculations. The ability to indicate which type of fasting a person is doing would make a difference (ie. water fast, liquid fast, or dry fast). The ability to add a meal data point (a simple total calories eaten) could eventually give way to doing real calculations (maybe even eventually using the body fat percentage, bone density, activity data of Apple’s health app). The ability to automatically update the body weight using the data of the health app would be beneficial, as well as exporting any relevant health data to the health app / HealthKit.

The app has much potential, but for now it barely goes beyond being a basic fasting time tracker.
