  • Very useful

    By reyenoe
    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.
  • Should have tried this sooner

    I’m 47. I was about 40 pounds overweight, five days ago. Now I’m only 30 pounds overweight. I’ve alternated between the 16:8 and 18:6 fasts and been a diet Nazi on myself. I’ve switched to a Mediterranean diet, and probably eat between 1,000 and 1,500 calories a day (I don’t keep an exact count, and that’s just a rough estimate.) Basically, I’m eating about half of what I normally do in food, and have cut out all alcohol and nighttime snacking. Have tried to walk/jog about a half mile a day and run around the yard more with my 5-year-old. I imagine if I exercise harder, I’ll turbo boost this process even more. On a scale of 1-10, my hunger pangs while fasting have sometimes hit about a 5. But it’s totally manageable and takes just a little bit of discipline. With this app’s countdown timer, it’s easier to hang in for the last hour or two, because the end is in sight. And when you do eat, you want to eat as healthy as possible so you don’t feel like the fast was for nothing. My beer belly’s days are numbered.
  • Best fasting tracker in the market

    By musicstix
    I’ve been intermittent fasting for about 2 years on and off. When I’m fasting, I find it extremely motivating to track my taste on Zero. I love that it has a few of the standard preset fasting times, but more recently I’ve been using the custom fasts which is an excellent feature. I’ve been back and forth on the 16-8 and 20-4 fasts so I set my custom to 17 hrs at the moment knowing I can build my way back up to 20 hrs. When I was regularly fasting and tracking on Zero consistently for about 3 months, I lost 15 lbs pretty effortlessly. I’ve fallen off the wagon a few times but I’m back on now and am exciting to keep tracking. The UI is really beautiful and easy and I love that it automatically updates my weight from my Bluetooth scale through the Health app. The only update I’d like to see is to have a more interactive view with the recent fasts feature. I feel like this page could be more helpful. Overall, 100% recommended to anyone looking for an IF tracker.
  • An essential download for weight loss

    By SharkosaurusRex
    I’ve tried countless diets and none of them ever felt good. I have severe anxiety and major difficulties with memory and would get torn between eating out with friends or sacrificing my diet, both options sending me into an attack. Until I found Intermittent Fasting. It’s the first time I’ve felt truly free and in full control of my eating, with the added bonus of giving me tons of energy. And there’s no way I would’ve been able to lose as much weight (20 pounds in less than two months!!) without this incredible app. It’s simple, efficient, sends beautifully easy notifications, and even has a dark mode. The app shows you how many people are fasting with you, has options for the different kinds of fasts, helpful information, and much more. If you’re even remotely curious about weight loss, control over eating, or IF at all, you need this app. It costs a whole 0 dollars, so why not give it a shot?
  • You guys messed up with the recent update

    By Stromba926
    One of my favorite apps. I used it all the time for my fasting journal. I just got done deleting it after the new version forces you to login your personal information… Not something anyone wants! I kept declining and every time I declined it would refuse to allow me to set the timeframe in custom fasting option. If I did not allow notifications it also prevented me from doing a custom fasting option. it now tries to link you through Facebook etc. All the different options that you added cannot outweigh the fact that you’re definitely mining for more information on your customers and this is a deal breaker. I’m not going to be forced to give my information and allow notifications when I don’t want them. The old version I just entered what time I started, what time it ended and it worked fine now I have to go look for another app or some other means of tracking my progress for fasting. Whoever came up with this so Called upgrade needs to have their head examined. People do not like being forced into corners where they have to allow notifications and or give their personal information!!!!
  • Actually free and very useful

    By Goatturkey
    This app is simple to use. Very intuitive. I only have the free version and I don’t get hounded by adds which is great. I don’t mind paying for Apps- I just basically refuse to pay subscriptions. I tried a few apps for fasting together and I didn’t like the others nearly as much as this one. I love that you can just hit a button to start a fast and another one to edit your start or stop time (meaning if I ate 30 mins ago but didn’t mark my fast as ending). The other apps were way to ridged. They would make you schedule all fasts for the week then would even automatically start and stop them. That’s not how my life works. I can’t eat and fast at the exact same second every day. That’s why I love Zero. It isn’t annoying. Doesn’t make you hate yourself if you break a fast lol. It’s just a great simple tool there to HELP you. Not there to overpower and run your entire schedule
  • Great motivation

    By Versteegta
    I first learned about the new subscription level on Zero from the Tim Ferris Show. I was excited to check it out because the free version has been a daily part of my life for over a year now. I’m more than happy to play a bit of money to an organization that adds so much value in my life. The addition stats and content library is amazing and help me validate in my mind I am doing the right thing for my health when so many naysayers think the idea of not eating for long periods of time are crazy. For all the folks complaining about being offered a chance to access to more information at a cost, think about how you get paid. You provide a service to someone else and that puts money in your account. How do expect app developers to operate any differently. And, at a subscription rate at less than $3 a month, they certainly aren’t taking advantage of anyone.
  • Love this App

    By Ergomuse
    Fasting is like meditation for me - really difficult habits to stick with. This App has helped keep me motivated through the tough times, through the periods of hunger that would have made me give up in the past. I love the visual aspect of the timer, the prompts to force me to check-in on how I am feeling, the data, and the articles and virtual "support" peeps. The app has made visible times of the day that give me the most trouble and tips from other users have helped me deal with them. The bottom line is that the fasting has created a stepped improvement in my energy levels which has carried over into my work productivity and relationships with friends and family and coworkers. I eat when I get home at 4pm and end up making much healthier food choices (food has never tasted so good after a 20+ hour fast). This has become the too App that I engage with throughout my day.
  • Used to be 5 stars...

    By emac-nyc
    The previous version of this app had a much more refined UI. I gave the previous version 5-stars while I give the current version 3-stars. This version is still functional, and it provides more information. That said, the current UI is unnecessarily busy and lacks simple but powerful elements of the previous version. One of these elements is when a person reached their goal the whole UI would change from the red to green. While this is a seemingly simple thing, it had a powerful effect on my experience. With the current version, I no longer get the satisfaction from glancing at the app during my day following reaching my goal nor do I get the resultant motivation to keep pushing on beyond my minimum goal. Another example is the interface for initiating my fasts. The previous version of the interface was more simple and in my experience more inviting to initiate a fast. For me, it was actually a small joy to press start on the previous version. Now I am faced with several pieces of unnecessary data surrounding the start button. It fees more like a chore than a pleasure now. There is too much noise surrounding the experience I am seeking I really value this app, and I believe it can help people. I hope these deteriorations and others are addressed and not worsened. The first version was so much closer to nailing it
  • Finally A Way Towards A Better Life!!

    By Sonya.A
    I just love this app. I chose the 16/8 fast and this app makes it so easy to fast. It will tell you the ending time based on when you start your fast whatever time that is and whenever I feel like breaking my fast before the time I look at how much time I have fasted and how much time I have left and just drink some fasting tea or bone broth and keep doing it!! I also placed reminders to let me know when I had gone halfway or to just check in to see how I am feeling while fasting. I love how it has the tracking that lets you know how many days you have fasted and the badges given for the days you have fasted. My next one will be the 25 day one and it is coming fast. After that is the 50 day then the 100 day and so on. It will be a great since of accomplishment to meet all of those goals, all thanks to this app. I love it!! Thank you so much!!!
