OPT OUT!

No option to opt out of a 7 day free trial. If I’m being forced to do a trial they’re banking on you to forget to cancel when it’s over. Didn’t know the economy was that bad that an app would stoop low enough to force your hand into a “free” trial. Deleted immediately. Developer must really need coins.

The BEST food tracker EVER

I started using Zero on January 31, 2026, weighing 159 pounds. Within just 3 months, I was down to 129 pounds!

I’ve followed this app throughout my entire journey, and the results have been incredible. I currently weigh 119 pounds and went from a size 10 to a size 2 in less than 6 months!

Zero has helped me stay consistent, accountable, and focused on my goals. I couldn’t be happier with my results.

THANK YOU, @Zero!

payment is predatory

will not allow me to say no to the free trial it’s offering to use the app

Scam

I have been a user for a while. I also wanted to pay for it only to be told the pricing is 80 a year when I went to cancel they said they will reduce to 37 for the next year. I mean they have a single license plan yet they choose not to display that. Absolutely a scam to get as much money from you as possible

UI update made it unusable

This was my go-to fasting app for YEARS but recently they completely changed the UI and have made it virtually unusable for me now (everything is compact, harder to find and tap tiny buttons). Also multiple pop-ups pushing for subscription services. No thanks.

Forces premium

I wanted to use the free version but I couldn’t get past a forced free trial, that required payment method for auto renewal- ugh

Don't waste your time

Previously I have used this app for a couple of YEARS. Now? You cant start another fast after finishing one. Do not waste your time with this horrible app. Will be deleting.

Fun little app

I have been using this for years to track my intermittent fasting.
As for tracking your fasting progress it was fantastic.
However recently I started using it to track my protein intake
It has an AI powered camera that does not work 70% of the time
It also overstates your protein assumption by 30 to 40%.
Since I’ve already used it for over two weeks now in this feature I am continuing for the time being
But they should not have rolled out a new feature without ironing out these bugs. The app also crashes once a day when you use this protein tracking feature

Yay you can custom 14 hour fast on free version

Thank you!!

Payment isn’t optional

Hate apps that don’t even let you check out how it is you have to pay for it to be able to use it and it’s a monthly subscription. Theres a 7 day free trial but what’s the point. Just make the app free or charge to download the app.

Every future now behind paywall

I’ve been using the app for over 4 years. Super disappointed they now block most features without a scam subscription. I wouldn’t even have a problem with a flat fee but the subscription model is horrendous.

Food tracker

The food tracker is not very good for me. I prefer to have an option to add food to a meal. It seems to me that you need to have all the food for that meal prepared and I put it at one time. Also I order to input meals in a specific meal section. On the upside. I really like the articles and update about getting into fat burning mode with movement

Annoyed

I’m annoyed that I paid for this the calorie estimates are awful. I had a meal of 200 calories and it estimated it to be 2000. It’s pointless.

14 hour fast only available in paid version

Really stink that I can’t select a 14 hour fast unless I pay the subscription

Stop spamming me

It is nagging me to upgrade, look bro I’m not paying you $$$ for eternity.

Do not subscribe

This app wil not let you do the trial it will charge you through apple and then never let you unsubscribe please don’t download this app it your trying to get the feel of fasting

Will not stop asking me to update

TLDR: won’t stop asking me to update my app when my phone old and I can’t update my IOS. I should not have to update more should it block me from using the thing. I now have to find a new app to use

Read before entering data.

No option other than zero plus. (Subscription) “Free trial” then forced pay (which you agree to up front to pay) should do this up front before collecting PII data.

Forced to Update phone to continue using

Was my favorite app but the new update is only available on ios 17 and up, i use an older phone and dont want to update it. Now the app is unusable

Start to a new start

I’m a father of 3
I got a huge stomach I need to lose it im only fat there.
Only way to lose belly fat is to fast
I love sugar an burgers
This app keeps me aware where I want to be and I see im making small improvements not doing it as well as I can be but I’m not stopping
