45 Positive User Reviews for Zero: Fasting & Health Tracker

Make it work for women

LOVE THIS APP! but what I would love even more is if there was an option to set a fasting schedule. Research shows that women need to fast with their hormones taken into consideration and as our hormones fluctuate, our fasts should to. I would love to be able to schedule the fasts based on my hormones rather than having just one target for every day, or alternatively having to go and change the target daily. Being able to set a weekly or monthly schedule would be super dope! I hope the developer

You just have to wait for the app to “unlock” to get rid of the paywall

I’ve used the app before and it was frustrating to see that when I redownloaded the app there was a paywall. I saw a lot of negative reviews because of that feature,

Love Zero

Lost weight. Saved cash on food. What’s not to like?

Kim

I upgraded and yet I get daily requests to “upgrade”. Why??

Love It!

It has helped me so much with reminders and the badges giving me motivation.

Love this app!!!

Peter Attia is the man and his backing is all I need. I’m a huge fan of fasting and ZERO gamifies it’s and adds community and accountability.

Easy to use

I’ve been using this app for the last month. Since I don’t IM fast by set hours, this app is a must for me. Love it!!

Excellent App

I love the app. Wish there was a little bit more free content available. The countdown clock is perfect and the regular checkins are a nice touch.

Such a great app

This app was everything that I needed it. Really good

Why 3 Stars?

The app freezes every time you hit one of the smiley faces. At the end of a fast, even if you hit end fast, I have to make sure to hit the button twice. if not, it will not count. I ended up fasting for one day several times because even if I hit the button once it doesn’t register and I am missing out on fasting because I don’t want to hit the smiley face and freeze up the system. otherwise, it’s a good app. And if you’re broke like me and can’t afford to buy all the amenities, it is still wort

I am sad

I have paid for lots of yearly memberships before that I regretted deeply. This time around I decide to be smart and only started with a monthly membership. Wouldn’t you know it, I am regretting it now because I wish I would have gotten the yearly membership. This things is almost perfect. They even thought of the things I didn’t think I needed and now I love them. Thank you

Zero

Easy to use and helpful.

Keeps you on schedule

I use this everyday for over a week and I’m already down 3 lbs

Great start

This app is holding me accountable in convenient easy way to stay on track. Thank you!

Amazing

I’ve only had this app for a couple days but I already love it so much. I’ve tried IF before but it was hard to keep up with it; I think this app makes it incredibly easier, more fun, and rewarding. The four pillars system and the streak is so motivating and the app gives you so much good information and advice. I love the design and interface as well and it’s one of the reasons I keep using it. Highly recommended!

Rating Zero

A friend recommended this app to me and I love it.

Glitchy

Had issues with ending fast stop from apple watch… hit the stop button from my watch but later learned it hadn’t stopped on the iPhone app. The very next morning I open the app to stop my fast and it’s asking me if I want to start my fast :/ where it should have asked me if I want to end my fast. I should’ve waited one more day before I bought the one month subscription 😫but because I was on the 7 day trial I was worried it would initiate the yearly subscription at $79 a day or two early.

Keeps hanging when you log mood

Asks you to log mood but the keeps spinning - I also thing the small circular pie charts it uses are not helpful

Wonderful app

All in one fasting, longevity, health app.

Used to be my favorite app.

I once said… ‘Don’t hesitate to use Zero if you plan to commit to IF.’ However, they’ve changed it. No reason to pay $9.99/month because there’s no added value or coaching anymore. You can track your measurables and clock, but other apps allow that too.

Bugs

Sleep calculation times are wrong. Can't switch ketone units. Using latest version.

Changed and Not as Good

There was an update awhile back and now it a little less user friendly to navigate. You can’t see your time easily in between fasts.

Love it

I like that it counts all my time and I don’t have to do it

Perfect to track your fasting goals!

Great app! Easy to use!

Easy to use and good information

Best free app to use based on features offered at no cost

Strike

I am loosing my strikes for no reason, i am on 16 hours fasting, but yesterday I pushed that for 24 hours, the app considered that I missed and lost my last strike although I started my next fast on every day timing . It been like that since I downloaded the iOS version, but the android i hade no issues with it , so do i miss something or is there something wrong?

THE Best Fasting APP

The APP not only provides you with all the knowledge behind fasting, but also gives very useful tips to help you on the way. I’ve been using the Premium version for 6 months, and wouldn’t hesitate to upgrade. The experts that contribute are the tops in their fields. Why would you go anywhere else?

Helpful

Enjoying the app, just upgraded and I like the extra features it unlocked.

The update ruined this app

Everything that was this app is gone. RIP

The best application for diet

The best application for diet Everything is perfect Thanks

Great

So far the app is awesome, tons of helpful information. The app makes it accountability easy and fun in a great way.

Helpful

Thanks for the free trial.

Zero Fasting App

I was initially skeptical. I have found the app to be well designed. I would like to be able to create my own “Activities” and decide how many calories are burned per minute of my created activities. But Maybe that is coming. But it is easy to use and tracks important data that I wouldn’t have thought to track myself. Like Sleep for instance.

Doctor recommended

My doctor recommended this app and I am beyond happy with my purchase. I have been using the app for about two months and have zero issues with it. Whether you are using it for living longer or weight loss, it gives you a customized home page with lots of tips and information.

The only fasting app I’ve used

I’ve used Zero for years now. I really love it, even though it’s become kinda confusing with all of the ads.

Love it

Simple easy to use can use features without having to pay….

Press Green button on THE EVENING BEFORE

Re: green button. A beginners suggestion is to start at the beginner 13 hours of course. Suggestion; Remember to push button the EVENING BEFORE. HAHA and NOT at 6:30am, which I did just now. Haha: 18 hrs Fast is recommended for expert. That’s me. (I.F. 16-8 since 3Yrs ago). So at 7pm is when I’ll press the button = 1Pm brunch

Great app. Could be better

I love this app and have been using it consistently for 80 days now. I’ve lost 20 pounds. My biggest pet peeve however is the fact that I cannot change any of my profile information. I cannot update my weight, my eating preferences, or anything else in my profile.

First week!

Makes it so easy to track start and stop times for fast. Love it!!

Perfect Intermittent Fasting timer app!!

Love this IF fasting timer. I’ve lost 40 lbs, but more importantly, IF has kept my blood pressure manageable. The timer is perfect with many fasts from which to choose. Also great info/references. I whole heartedly recommend!!

Zero really helps me

I was on zero…. Got a new phone…. Had trouble setting it back up! I thought I could just “remember!? Yea, right! I’m happy to have Zero back!

Awesome

This app help me maintain my weight more than anything.

Fine but app spams notifs

I went into the app settings and turned off all notifications except when I need to fast. Even after I did all that I keep getting notifications on “tips and tricks” or some other useless thing I dont need.

Software bug in clock affecting duration of fast

There’s a sw bug that makes the total fast duration look like it’s 1 minute short but not all parts of the app display the same info. For the same fast, it looks like it’s 15:59 in one place if the app and then looks like it’s 16:00 in other parts. This app has one job… to record time properly. Can you please fix this sw logic?

Not upfront with cost

Hi I was quite frustrated about needing to answer a number of private questions as part of onboarding. I’d like to be in choice about sharing my weight and height and a number of other questions. After putting in the time to put in all my information I learn that there isn’t a free version. That’s fine you deserve to succeed as a business but I don’t want to pay a monthly fee for my once a year 5 day fast. I just wanted a cool countdown. I really didn’t feel respected that the app sucked in m
