Perfect app. Very simple 5/5
Dead simple timer to keep you on your fast.
Am I missing something? 1/5
By Paul Horne
Apparently this is for people who can’t remember their time window? If you decide to eat between 11a - 7p why do you need an app that does nothing but remind you of that time? Bizarre. I’m a fan of Kevin Rose but I don’t get this.
I use this when I need to refresh my body after I ate foods I that are bad. It is really helpful to let me know how long I have been fasting so I don’t go over board.
Pretty Good 3/5
I would have given it more stars if the customization fast could be individual fasts and not set for a week. I might do a 16 hour fast and the next day a 72 hour fast and then maybe 23/1 (one meal a day). It's not always the same, I just wish I could reflect that in personalization.

Awesome App 5/5
Have tried many apps for tracking but this is by far the easiest to use. Really easy to adjust times when needed.
Love the app! 5/5
This app is super simple to use and I love that you can pick which plan you want to follow. If I have something timing me, I’m more likely to stick with my fasted times/eating times and this is perfect for it :)
Love this 5/5
It’s fun to time how long I can fast for.
Simple and effective 5/5
Like the title says, love the simplicity. You can tell this app was designed by someone who knows the fasting process. Thanks Kevin Rose.
It’s ok 3/5
This app is ok. Nothing really special. I like that they have videos about intermittent fasting. I just wish there was more to the app like do’s and dont’s of fasting would be really good for beginners.
Very User Friendly 4/5
This app is very easy to use and very aesthetically pleasing. The only thing I would change would be if they could automatically have the time for the eating window to occur instead of having to manually stop your fast.
Perfectly Simple 5/5
I’m a fan of single purpose app’s and really love the disciplined approach of Zero - just the right amount of design mixed in with empowering utility.
Great App for counting hours of intermittent fasting 5/5
By CG Fagerhaugh
Simple counter enables you to keep track of fasting hours and dates. I love fasting. I heard about it from DAMY health. Encourages you to fast and see progress and record of fasts.
Great app 4/5
Just wish the fasting options were more customizable. There is a great foundation here for a wonderful all-in-one app for intermittent fasters
Simple and to the point. 5/5
Thank you many times.
Great app 5/5
Really simple app wish it ran on my standalone Apple Watch
Zero is great, efficient, and intuitive and just what I needed to get a better hold on intermittent fasting.
You need to start fasting today 5/5

Quit lying to yourself and get on the path
Simple and effective 5/5
By Noah’s Wife
A very easy to use app that is simple and an effective reminder. I use it as an accountability tool to “keep me honest” at night and to help me to stop mindless nighttime boredom eating. It just works...without being complicated or overly cumbersome.
So far so good 3/5
I don’t dislike this app, but need more time with it to decide how helpful it is. But since I have gotten more than one message asking for a review here it is. Once I have more time with it I will have a better idea.
Count down 4/5
I like this app, but it would be nice if it had a count down feature so you can see quickly how much time is left in the fast.
What does night eating mean? 3/5
By Night eating?
Frustrating that it is not explained or can be changed. I am fasting so there is no night eating if any kind.
Helps me not eat late 5/5
I have tried to avoid eating and snacking after dinner previously, but know the app is keeping track of the time helps me stick to it.
Great app! 5/5
By Michael Gainer
Been using it for awhile! Works great as a fasting tracker and also lets you customize your own Fasting times!
Please add count down option 3/5
By Balto app user
It’s small thing, but adding the option to change clock to count down rather than up would be nice. Viewing history for a month would be great too. Otherwise, it’s a good simple, visual way to look at your daily IF regimen.
Keeps track of time only 4/5
It’s a great app for tracking how many hours you’re fasting and seeing it on a weekly basis. However I wish it could provide me with some kind of alert as to when it’s time to break my fast. I wish I had a reminder rather than having to open the app when I think it’s time to eat.
Lost history when switching phones 3/5
I like the app but when switching phones I lost all my history despite exporting the data on the old phone; there’s no way to import it on the new phone.
Love this app!!! ❤️ 5/5
keeps me on track !! Super easy to use
Simple & easy to use 5/5
Simple setup. Easy to navigate. I really like that it keeps record of my fasts.
Simple, effective, inspiring 5/5
My first voluntary review! I heard about this app from an article on Kevin Rose and I read, and was inspired to give it a try. It's a very simple fasting app, but you can tell a lot of thought was put into creating it. Besides the fasting timer, and data charts, it also features the science behind them. Give it a shot, you have nothing to lose
No reminders 2/5
A good app in theory, but I really need to be reminded to set when I eat or when I start fasting. The only notification you get here is when you complete a single fast goal. What about when I start my fast the next day. Constantly forgetting to set it from within the app so you have to reset the time, makes it way more of a chore.
Great app. Simple. Please add Apple Watch support 4/5
App does what I need it to do. (Count 😆). But I’d like to to work with my watch so I can start and stop and see elapsed time that way.

Promotes eating disorders 1/5
I see this app being used a lot on social media by people with eating disorder to help them starve themselves.
Great App. 5/5
Nice and simple.
Easy to use. Clear display. 5/5
Easy to use. Clear display.
Simple, easy app. But… 4/5
It needs better support for timezones. I jump timezones regularly and while it seems to calculate the amount of time fasting accurately, it doesn’t display the times in a way that makes sense when jumping timezones.
Also a 3D Touch menu for Start/Stop fast would be an awesome addition.
Support group 5/5
I’d love to see a support group as part one this app.
Simple easy way to track your IF cycle 5/5
While it likely won’t survive an IOS update overnight, it should be reliable in every other way. Start it after dinner, let it run while you sleep, and then try and push yourself those last few hours to hit your target.
Great tool! 5/5
By JFB Healy
Keeps me focused on my IF protocol, it’s easier knowing exactly how long I’ve been fasting and how long I have to go.
No way to set into the future 1/5
I wanted to get started/plan a start but you can’t set the start time for a future date.
Prettier than other similar apps 5/5
Does the basics. Visually pleasing. My favorite of the currently popular fasting apps.
Excellent app for tracking fasting activity! 5/5
By Babu Si Nur
This app helped me track fasting activities and it motivates me to stay focused on my progress
Love this app! 5/5
By IF for weightloss💕
Makes fasting easier by never having to guess how long u have been fasting or how much longer you have until you reach your goal
Nearly perfect to track fasting 5/5
I would like to see 3D Touch to start or end a fast, a way to see time remaining until fast complete, and reminders to start fasting.
Pairing is caring 5/5
I can't find one app that gives me completely what I would like to see in a fasting app, however, what I done is pair the app to fit my liking. I pair this app with one called fasting buddy for it gives you the time range for eating once fasting has concluded for the day and even gives you notifications before and after that time. I then go back to start a new fasting day on here. While I like these two apps together, separate, it's just meh.
All the app does is count down to your fasting time. I know to eat between 2-6pm. I don’t really need this app.
Extended Fasting 5/5
I love using this app for extended fasts. I Intermittent fast nearly everyday but occasional do 24 - 120 hour fasts.
Simple, Elegant 5/5
I love it. Just want I want and need and nothing more.
