### 2/5 — Used to be so much better.

*2026-08-14, version 7.12.0*

This app used to be so much more user friendly. Unless they revert to an easier way to set and track your fasts I'll never go premium again. Sometimes change is just change. It doesn't make it better.

### 3/5 — Great app, with issues

*2026-08-11, version 7.12.0*

By and large a great app, but has some issues that the team needs to address (doesn’t read Apple Health data it has access to; instead forces me to do enter exercise and food intake info I’m already entering in other apps). Also needs a feature where when you break your fast, it gives you a countdown to next fast based on the previously selected fasting program (with options for how obtrusive you want the notifications).

### 1/5 — Find a different app

*2026-08-05, version 7.12.0*

I used zero for years on and off. Started fasting again recently and learned you can’t see ANY HISTORY AT ALL now, even your previous day’s fast, without paying for their “premium subscription.” 
Why should I pay $10 monthly for a timer and my own fasting history? Zero is going downhill. Find a different app if you don’t wanna be irritated.

### 1/5 — Zero is a clickbait teaser to get you to buy zero plus

*2026-08-04, version 7.11.0*

Zero gets a zero for a teaser rate and then forcing me to pay more in zero + to get the promised features. Bad practice.

### 1/5 — No free features

*2026-08-03, version 7.12.0*

It irritates me when an app makes you go through all the whole signup process and only to find out everything is behind a paywall. No thank you.

### 1/5 — Only for if you can’t tell time.. support is useless

*2026-08-03, version 7.11.0*

Pretty much will count zero out for good, signed up for a free trial. Wasn’t notified for renewal and was hit with a yearly price for an app this useless. reached out to support never helped.

### 2/5 — They made it difficult to use.

*2026-08-03, version 7.11.0*

It used to be pretty easy and straightforward, they made it to difficult and confusing now, Incant figure out how to start a simple fast now after they botched the interface, I’m giving two stars because they ruined my fasting app.

### 4/5 — Super helpful!

*2026-08-02, version 7.11.0*

Really like this app it’s very helpful! Had it a couple years, but recently they added a calorie tracker in a snapshot, I love this feature! The only thing I would change is if they could show how they are allocating the calories to the individual ingredients, because sometimes they are off by quite a bit. I just go through and adjust where I can.

### 1/5 — Scam

*2026-08-01, version 7.11.0*

Would pick zero stars if I could

### 1/5 — Scam

*2026-07-29, version 7.11.0*

You sign up for a free trial but when you go to cancel, they make it so incredibly difficult. It’s almost impossible. I still cannot figure out how to cancel. They send you in loops never-ending loops that don’t go anywhere. It’s a scam.

### 3/5 — Idk

*2026-07-28, version 7.11.0*

I bought the subscription but I can log anything.

### 1/5 — Worst app ever

*2026-07-25, version 7.11.0*

Honestly I feel like I’ve been scammed. They signed me up for the most expensive subscription after my trial and charged me a $135 for a family plan. Which is ridiculous this is a terrible app and is not ever worth $135 dollar please take my advice and never ever use this app they are robbers and it’s free app isn’t even worth it find another any other fasting app. This one is horrible and will take your money the worst experience I’ve ever had with an app on Apple.

### 2/5 — Not worth it

*2026-07-23, version 7.11.0*

I used this app when it was free and it doesn’t have much improvement. Don’t bother

### 1/5 — everything is behind a paywall now

*2026-07-22, version 7.11.0*

i used to use this app years ago and found it to be SO helpful to keep track of my fasts and how my body was during them. downloaded again after i had gained roughly 30 lbs from unexpected health issues and i can see basically nothing unless i pay for it. this is unfortunately not how the app used to be at all and was so disappointing.

### 1/5 — I don’t recommend

*2026-07-19, version 7.11.0*

It would let me cancel my subscription and they charged me $89.99

### 1/5 — New interface sucks

*2026-07-18, version 7.11.0*

Since moving functionality and ease of use behind the Zero Plus  paywall the app has become difficult to use so I will be deleting it and moving to something else.

## Most critical reviews (10 lowest-rated)

### 1/5 — You must subscribe to do anything

*2026-08-13, version 7.12.0*

Horrible app. Forces you to create an account and give all the personal info then won’t let you do anything without a paid subscription.

### 1/5 — надоели

*2026-08-13, version 7.12.0*

лишь бы бабок срубить

### 1/5 — Wanted simple app without forced option of payment

*2026-08-13, version 7.12.0*

Wouldn’t recommend this. The focused payment for free trial is unreasonable, no back options to close the page, closed app and opened again payment option pop up, terible app 👎👎👎👎

### 1/5 — Failed at 1st hurdle

*2026-08-13, version 7.12.0*

Can’t get started as I’m In a continuous loop between bank app authorization and zero offering different trial periods…..

### 1/5 — Another “free” app

*2026-08-10, version 7.12.0*

Stop marketing as a free app if that means a 7 day trial followed by payment that’s not free.

### 1/5 — Waste of time

*2026-08-08, version 7.12.0*

Waste of time

### 1/5 — G

*2026-08-08, version 7.12.0*

Cannot use the app unless I agree to signing up for a free 7 day trial with $149 yearly payments commencing after the trial. No thanks

### 1/5 — Be Aware - Scam!

*2026-08-07, version 7.12.0*

BE AWARE

Zero star was not an option.

I’ve used the free version of Zero since 2021 and was recently hit with a $69.99 charge for a subscription I never knowingly signed up for. Let’s be honest: this app isn’t remotely worth $69.99 to begin with, especially when there are plenty of comparable—and better—options available for free or far less.

What’s even more disturbing is that I’m far from the only one reporting unexpected subscription charges. There is a clear pattern of complaints from users experiencing similar issues.

Be very careful with this app and check your charges. I certainly won’t be using it again.

### 1/5 — Not free anymore

*2026-08-07, version 7.12.0*

Has a Paywall…

### 1/5 — No button to start a fast

*2026-08-06, version 7.12.0*

What happened? It used to be so easy to start my daily fast with a simple button. Then the option moved to the + menu, but after the latest update, the option to start a fast is gone. The UX has gotten worse with the updates.

### 5/5 — Zero App

*2026-08-05, version 7.11.0*

The Zero App was a significant part of my weight loss journey over the last year.  It held me accountable to my self.  The in App challenges are a great daily motivator!

*2026-07-25, version 7.11.0*

### 5/5 — Changed

*2026-07-24, version 7.11.0*

Loved it when it was free but now forced into 7 day free premium which I don’t! Just want the free download one which is mega but it won’t let me without the 7 day free trial of premium very disappointed

### 5/5 — Makes fasting easy

*2026-07-22, version 7.11.0*

*2026-06-06, version 7.7.1*
