## Zero Description
Zero is the all-in-one fasting tracker and nutrition app built for real results. Most fasting and weight loss apps stop at simply tracking fasts or calories. Zero connects the full picture — fasting, protein, meals, hydration, and habits — so you actually change your body composition, not just your eating schedule.

Here’s how Zero helps you get there:

• Track your intermittent fasting — Engage timers, streaks, and insights keep you stay motivated and consistent on your entire fasting journey.

• Log meals the smart way — Skip the tedious manual meal entry routine. Snap a photo and get instant macros, protein composition, and clarity on how effectively your meals support your goals.

• Hit your Protein Score — Track your personalized daily protein target that adapts to your weight and goals. Better protein = better satiety, better muscle retention, better weight loss. Zero makes it automatic.

• Complete the equation: Fasting + Protein — Most people fast or track meals. Zero brings them together so you lose weight, protect muscle, and avoid the pressure and guilt of traditional calorie trackers.

• Stay hydrated to power your fasts — Water tracking helps you maintain energy, reduce cravings, and support metabolic function throughout the day.

• Build healthy habits that actually matter — Track movement, sleep, mood, and other daily pillars that reinforce your fasting and fueling routine.

• Challenge yourself — Hit protein targets, maintain fasting streaks, and stay accountable with motivating challenges built around outcomes, not vanity metrics.

• Learn the real science — Understand how fasting, protein, and hydration work together for sustainable weight loss and metabolic health — with insights from leading experts.

• See measurable progress — Watch your streaks grow, your protein consistency rise, and your body composition improve with clean, insightful trend views.

Whether you’re starting out or optimizing an existing routine, Zero gives you the structure, guidance, and clarity most apps miss.

## Zero Reviews in Canada

### *---- "you have to pay"
money grabber
-- i hate te~mu, 2025-01-22

### *---- "No free option"
You cannot even get to the app to try it without accepting a 7 day free trial.
-- REEelleBEE, 2025-01-19

### *---- "Too many interruptions"
The app is almost unusable because of all the prompts to upgrade to Zero plus, multiple times in a single session. Used it religiously before but switching to an alternative.
-- alongcamemia, 2025-01-15

### ***** "Great app !"
Love the app so far , i would love to see access  to the Dynamic Island and always on display on my iPhone
-- philoup68, 2024-12-15

### *---- "Waste"
These companies always want to gouge you forever. Maybe mention that you want to leach off of customers indefinitely so that they can use your timer.
-- Ugfjjgtgkktefbj, 2024-12-13

### *---- "Not Free"
Can’t use it without a credit card….deleting it immediately
-- Teach7777, 2024-12-11

### *---- "not free"
this isn’t a free app, once you get past signing up there is a pop up that you cannot exit out of that makes you pick either a 7 day fee trial or $99 per year, either way you Have To pay to use the app. total garbage
-- asha_c, 2024-12-07

### *---- "Greedy"
App makes you register before telling you that you can’t use it until you pay. Waste of time.
-- Spoontech, 2024-12-04

### ****- "New user"
I started fasting a month ago. This is so much nicer than keeping notes. I haven’t figured out yet where to track meals/food. I’d also like to see rebounding added to activities.
-- Ms Vvvvvv, 2024-11-28

### *---- "Not Free"
X to exit “free trial” prompt does NOT appear.  Disappointed was really looking for to using this app.  Waste of time.
-- A lot of adds & new look, 2024-11-27

### **--- "Stop changing it"
It used to be bright and easy to read.  
Everytime I open it now, the interface has changed slightly, to a point where I feel like it is a completely different app then when I first started using it. 

And why did you make the font size of the start and end times microscopic? And the fasting ring is burgundy on black?

I would have totally paid money for the app as I used to know it, but it has changed too much.
-- Hammergirl, 2024-10-30

### *---- "I’ve paid annual for two years now.."
And it’s disappointing that the widgets I depend on don’t even work anymore, it’s just a blank widget
-- Arwina Mogul, 2024-10-29

### *---- "Can’t close pop up for paid version"
I was told this app has a free version but as soon as you open it the pop up to try paid version appears and cannot be closed.
-- Maddie Evelyn, 2024-10-29

### *---- "Can’t pass the sign in step"
Have to choose either free 7 day trial or 1 month subscription.
-- Cslili, 2024-10-27

### *---- "Free version is hard to access"
Tried this app after LIFE fasting app shut down. Zero was too pushy in getting you to pay and you couldn’t easily access the free version. They sent way too many emails as well. I’m using Fastic now
-- Stone craft app rater, 2024-10-16

### **--- "Ridiculous amount of pop ups"
This app is unusable every time I open it or end a fast it keeps giving pops up pushing me to subscribe.
-- SenpaiSus, 2024-10-13

### *---- "Doesn’t do the one simple thing I wanted"
If you need something to keep track of how long you’ve been fasting, just use the timer on your phone.
This app shows a chart of how long you’ve been in your “fat burning zone” but can’t keep simple track of hours and minutes and display it in an appropriate format. Surely peak fat burning varies from person to person anyway.
I paid for a subscription so it’s not a free/paid version issue. I won’t be renewing the subscription.
-- Fannyprice, 2024-10-07

### *---- "no longer free"
Ridiculous greed.
-- Z-A-N-D-R-O, 2024-10-02

### ***-- "App needs improvement"
Sometimes I start a fast and change my mind. The app doesn’t have a way to delete a timer I started. Hopefully I can find an app that allows this. There are things to like about the app but this app doesn’t meet my needs.
-- LemonPress67, 2024-09-23

### *---- "No longer free"
No longer free, and does not let you delete your account. Developer response to another review 4 years ago says Zero will always offer a free option, I guess not.
-- Tye Dream, 2024-09-19
