Zero - Intermittent Fasting

I like the interface, but there's several things that seem to be broken in the Free version. For example, streaks & milestones are not being earned or incremented. Also, the week view for the Total Fasting Hours chart is not accurate. It has not shown anything since 10/28 and the hours that are displayed for that day do not even reflect what was recorded for the fast itself. -- If you don't care about any of that stuff and just want to track your fast each day, the Today & Calendar views work.

Why does using the app require an internet connection? I just want to end my fast so I can eat but recently I've had to close out the app multiple times for it to be able to load so I can end a fast, absolutely bad UX. If you really want the data then at least just have it sync the next time its able to but don't prevent me from ending my fast.

I've used this app for YEARS, but it's busted after the last update. I've dealt with some of the weirdness with the timers being off if you don't use the app for a while, that's fine. but now I can't even open the damn thing. I can KINDA use it with the widget, as in I can stop and start it from said widget, but I can't correct times or change it from my previous setting. the app just straight up doesn't open now. no number of resetting or uninstalling and reinstalling helps. PLEASE FIX THIS! 😭

I've used this for a long time and I'm not impressed with the latest updates. For in, I achieve my fasting goals (16hrs+) and some of these green circles at the top are not highlighted - almost like I missed something but I have no clue what. I also wish the previous timer would come back. Weekly averages were clearer as well. Meh!

Was loving it until I got to day 27 out of 28 on a challenge & for some reason I was removed from the challenge... Calendar says I met the goal but when I went to join the challenge again the screen was mostly blank... Kind of a bummer.. That challenge helped encourage me to not fail so I guess I'm grateful for that, just confused by the glitch. Still 4 stars because it's really helping me to be intentional! Easy to use. *after latest update I can't edit my fasting times 😔

I honestly can find no faults with this app. It is easy to use, has lots of options and I use it every day for alternative day fasting. It is 100% a winner in my book. The only small suggestion I would suggest to the owner is allow an option where someone can buy a lifetime or one time license. The idea of another subscription option is just for me too much. Other than that, I give it a solid 5 stars and encourage you if you are considering fasting as an option in your life to use this app!

Have been using paid version. As of today, cannot use the app at all: "This version of Zero is no longer supported. Please update to the latest version to continue using the app." I uninstalled/reinstalled, cleared cache - no change. It would be sad to lost quite a bit of data I've accumulated over the years. Hope the issue is fixed. Update: the bug was fixed

Pretty buggy. It does what it needs to do, but for certain prompts, I have to click through 2-3 times for it to go through. Fitbit sync doesn't really work, and the function to add activity isn't working. There's no way the premium version is worth $10 a month; think of the value that other subscriptions offer for less. Better, free apps exist.

Really enjoyed all the free perks of the app before they switched it, took everything away, and made people start paying for the things we got for free for years. Thanks for the response; however, I know what plus does as the app itself, before you started charging everyone, did the same things. At minimum it was giving fasting zone information which was extremely helpful. I've switched to a new app called 'Fasting Tracker' that does what this app used to do for free.

I do wish you offered more things. i would like to see an option that connects to fitbit or some weight app, like my fitness pal. i dont record my weight on my email. i would like to see an option for measurements as well. maybe a place you can add a journal to see how you feel that day? theres just so much more you could add. id pay for the app too. one time payment. other then that. it is a great app for basics.

I love this app. I have been using it for over a year now and I think it's the best one out there. The app has a reminder to let me know when it's time to start fasting and it allows me to edit my fasting time. For example, if I started fasting at 9pm but forgot to enter it then remembered at 10pm, I can go back and edit my starting time. The app also has goal badges for motivation. When you surpass a certain number of fasts you receive a badge. I will always use this app. Love it.

Used this app for aver a year and I enjoyed it. I was excited when they were launching the premium version up until I realized you had to take out a small loan to pay for this apps annual membership.. Why make the cost so high for a relatively straightforward application? IMO The app should remain simple, easy to use, and priced reasonably if you're going to insist on keeping functions users can't access visible. The customer either unistalls or gives in. Sadly I had to choose the former.

I find strange that ketones levels are recorded only once a day and without a time of day (or time of fast) attached to them. it makes sense for a day long fast, which is likely the least frequent type of fast. for hours long fasts it would be useful to test glucose and ketones every few hours to understand how they change wrt to start of fast and start of day. probably won't be used every day, but once in a while to get a detailed understanding. I also cant find a way to sync with google fit

The app keeps glitching horribly. Tons of little "ghost fasts" keep appearing, ie it logs a random fast that I never did (for a stupid amount of time - some of them are 1877h)! I can't delete them and they break my fasting streak somehow. Oh, and for added frustration, when I try to delete them they just get longer. This is driving me insane.

This was a great app 'til it got accidentally deleted off my Android phone. I downloaded it again & now it gives me no prompt to sign in. It only gives me prompts to create a new account. I don't want to create a new account, as I have almost one year of daily fasts logged on this app. It appears this is only a problem on Android. My friend has an iPhone & just for the heck of it, she deleted & then reinstalled the app & was able to sign in with her email again,no problem. Please fix for Android

I like the app and tried the zero plus trial. I logged in food to help with my journey. Later I did subscribe to the Zero plus however, now when I wish to log food it opens a window and immediately closes it. This was one of the reasons I joined. Reaching someone to help is nearly impossible. All the replies say is that I logged in to the wrong account. That is not the case. I gave it a 3 and that is too much. So disappointing.

The only other thing I wish this app did was let you keep a log as to why you cut your fast short or extended your fast longer than your normal fasting period. And also show the stages of your fasting (like what your body is doing in the time you are fasting.) The app has slowed down I'm assuming since the last update. It doesn't load as fast as it did when I first got it.

Ok so I love this app and have been using it everyday for the the last 5+ months. Plus is TOO expensive and not worth it. I like the fasting zone feature. But that's it. So many of us don't use the education section at all. If I want the fasting zone feature, i would also need to purchase access to articles I will never use. Maybe add tiers of membership and a lite version for people who only want the fasting features without the educational part? And Also zones are free in other apps.

Update 7/7/24: Uninstalled. Issue not resolved, and developer response is not helpful. You know the issue is widespread, I shouldn't have to email you. When it works, it's handy. Unfortunately, most of the time it won't load, just keeps spinning and spinning. I have to wait until the next day to edit the start time, for example. I also can't go back and add a fast if I forgot to push start - or at least I can't get it operational long enough to find how to do that.

I love this app. It helps keep me on track and motivated with fasting. My only complaint is that the reminder feature is a little wacky. I am on a Samsung Galaxy S9+ and have my fasting reminder set for 20:00 (8:00 PM). However, there seems to be no rhyme or reason to when the push notification comes up on my phone. This morning I got a notification to start fasting at 10:43 AM. Would be a five star app if that wasn't happening.
