## 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 United Kingdom

### ***** "Best way to fast"
Used many apps this is my favourite, it’s simple and easy to use.
-- kittycatshakespear, 2025-01-14

### ***** "App"
Fantastic App for Fasting. Love it
-- Solenn Le Floch, 2025-01-10

### *---- "False advertising"
Came across this app in a review by good housekeeping, they said it was a good app to use as a newbie to IF, a free app with good free features  with premium upgrade (payable) content for more advanced. Downloaded and was hit with a paywall.
-- Phoenix2qt, 2025-01-09

### *---- "Please improve gestures interpretation. One of the most frustrating app"
Lots of bugs for example app cannot read touch screen and/or gestures input with any precision. The idea and the app are useful. Implementation could be very much better.
-- lgalx, 2025-01-06

### *---- "Make sure you plenty email storage."
If you want to get 10 to 20 spam emails per day, download this app 👍.
-- lee.brook, 2025-01-06

### *---- "made me sign up to tell me its £70!"
Made me create an account, fill out all my information and then an unexitable screen popped up saying i had to do a a premium version. 7 days free then £70! Glorified stop watch. Do not market as a free app if it isnt!
-- beckybetsy, 2025-01-04

### ***** "Incredible Fast Tracking App!"
This app has been a godsend the past 4 months & now going into 2025 too, helping me to improve my relationship with food, eating intentionally, becoming healthier, and losing some excess weight!
-- RubyAea, 2025-01-01

### ***** "Cool app!"
Really nice app. Recommend
-- Даша Горшенина, 2024-12-16

### *---- "Not actually free"
Not useable without a subscription
-- katij23, 2024-12-10

### *---- "Takes your data for nothing"
You have to create an account where they take all your personal data and asks to access data on your phone. Only after you have given it this data does it then say that you can only get a 7 day free trial after which you have to pay. 

Disgusting business practice. You can’t even delete your account without setting up the trail!
-- balmey28, 2024-12-09

### *---- "Until they let me get rid of that stupid AI bot…"
…cluttering up the home screen this gets one star.
-- ep1965, 2024-12-08

### *---- "No free option"
You are forced to subscribe straight away. 
But first they will collect your data! Absolute scam!
-- Fenka_a, 2024-12-08

### *---- "No free option"
There’s only free trial and no button to cancel that offer
-- andywswan, 2024-12-02

### **--- "Great app let down by notifications"
A shame that you are bombarded with notifications and offers to upgrade. The upgrade price is totally unrealistic as most people just use this as a timer to log their fasts. Also the count down feature doesn’t work for me. It will only count up. When you start a fast it starts it from the second as well as the minute. When you end a fast it ends it at the second rather than the minute. When editing fast length you are not able to edit the seconds. I find this irritating.
-- Catelfinel, 2024-11-30

### *---- "It used to be good. Now they just want money"
I used to love this app and would use it on a daily basis. Then overnight they changed it to charge you a ridiculous amount for something many other apps do for free. Don’t waste your time downloading as it’s impossible to use now without the high costs
-- Laurenp414, 2024-11-26

### *---- "this app is paid"
this app is not free and you’re forced to pay you get a 7 day trial and if you forget they charge you £68
-- rxm___, 2024-11-17

### *---- "Absolute rubbish"
Forces me to change my dream weight to their recommended weight even though I don’t want to
-- yuixen, 2024-11-16

### ***** "Great sound advice"
Easy to use to track your fasts, great videos of the current science of benefits of fasting.
-- Papajst, 2024-11-11

### *---- "Can’t do anything without paying and it’s expensive"
This is a crazy expensive app and you can’t do anything without paying.
-- All nicknames are taken!nnnnn, 2024-11-08

### *---- "Beware!!!"
Suddenly took £67!!! from me!!!! No warnings and no way would i of signed up to that!! I only used it for a couple of weeks. I’m sure they’ll tell me this my fault somehow -  i’m so angry!
-- Zigzaging, 2024-11-08
