Wonderful app for Intermittent Fasting (IF)

This app is truly a lifesaver! I have an unusual manifestation of Temporal Lobe Epilepsy and must stick to a low carb diet. I recently had a back surgery that went horribly wrong. I was forced to stay in bed for almost a month! I had to eat whatever was brought to me from the local restaurants and fast food joints. Prior to that, I had been on a strict KetoDiet for years! I gained 15lbs and felt terrible. After my recovery, I restarted my KetoDiet but the weight wasn’t coming off. I was also retaining water and I felt terrible. Then I learned about Intermittent Fasting (IF). Thanks to this wonderful app, I am losing 2lbs a week and I feel great! I generally do the 16 hour fast and then the 13. With the custom setting, I can do a 24 hour fast for religious reasons as I am a Christian and we are taught to fast and pray. But that’s my own personal decision. The custom Fast lets you use a slide to choose your own number of IF hours. So if your a newbie or might have issues with food, you can ease yourself into a full 13 hour or 16 hour or a longer period of IF! That’s what’s so wonderful about this app. You can also chose to count your IF hours up or down in order to keep yourself motivated.

Full Featured App With Nice User Interface

I’ve been on a calorie restricted diet for years making very slow progress on my weight loss goal. I decided to start recording the time of my last food each day knowing that the time you eat may be as important as how much you eat. It quickly became a burden and a clutter on my calendar so I went looking for an intermittent fasting app. Since my original interest was just recording the time of my last meal I wanted a simple low/no cost app. I found only one free app that didn’t have in-app purchases to goof up features. Zero was that app plus it had the bonus of a 4.9 rating. To my surprise this is a full featured app with a very high quality UI . It has historical tracking of your fasts and can read or write to Apple Health. The app had so much IF learning information that I began a 16:8 schedule. I’m only on day 4 but my progress has improved while keeping exactly the same calorie goal. No matter what your needs to track IF or TRF you are in for a treat with a professional app to assist you.

Very useful

I have been using the Zero app since March of 2019 and have found this app very useful to reach my health and other goals that I have. The developers keep improving the app in many useful ways such as improving journaling, adding more knowledge to the learn feature and improving the stability and function overall. If you are wanting to track your first fast, look no further my friends this is the app to get. Also be sure to check out their Oak meditation app, it is amazing.
One suggestion: I would love to see new features on the Apple Watch. For example have the fast tab show up on the Apple Watch that way I can quickly select the fast that I need.

Also if you could please add the Oak app to the Apple Watch and have the ability to select and download a meditation or breathe to the Apple Watch. This would be awesome to have while away from my phone, that way I can put on my AirPods and do a quick mediation or breathe session while on break or lunch.
Thanks for the hard work.
