## 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 is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your doctor or qualified healthcare provider before making any changes to your diet, fasting routine, or health regimen.

## Zero Reviews in Portugal

### *---- "Premium trial is mandatory"
The annoying free trial thing wont dissapear, no matter what the company bots are saying about there being an x to decline it. No x, and it no matter how many times e close and reopen the app it wont go away. Stop gaslighting me
-- mlvpg, 2024-12-30

### ****- "Boa app"
Excelente ferramenta para quem pratica o jejum intermitente
-- RukaDurt, 2024-12-13

### ***** "Useful for me"
Good for tracking time and motivation during prolonged fasts, but limited to 168 hours.
-- Nickole812, 2024-10-28

### **--- "What happened?"
It used to be the best fasting app, but now it doesn’t even show in what fasting zone you are.  It’s a shame really.
-- imfineinred, 2024-08-10

### ***** "Perfect."
Perfect for fasting. Great tips and knowledge.
-- Rob-0000, 2024-07-28

### *---- "Waste of time"
It’s not free, when you create an account and do all the steps to start using the app, you then get a prompt for a 7 day free trial with no option to close it, you either accept it or accept it
-- Khali258, 2024-04-21

### ***** "Crítica a aplicação"
Aplicação dedicada ao jejum intermitente sem mais extras.
Disponibiliza informação que ajuda á compreensão do jejum intermitente  e alguma meditação.
Aplicação simples, funcional e rigorosa.
-- ffgaspar1, 2024-04-20

### ***** "Excelente"
É possível editar os horários de início do jejum, compatível com a app saúde da Apple, podemos inserir as refeições com fotos de maneira resumida, exercícios físicos e horas de sono. Muito bom!
-- Rachelll123, 2023-10-13

### ***** "Absolutely love the app"
The app is amazing, really helps me to stay consistent with my fasting. The paid subscription is totally worth checking out (although the free features and articles are already great). Only one this is missing for me: the Apple Watch app doesn’t have the timer since last fast (you can start or end fast from your watch but you can’t see how much time elapsed since last fast)
-- JP2JP88, 2023-06-13

### *---- "Biggest downgrade ever"
Used it a year ago and absolutely loved it.
Went to use it again today to track another extended fast and was so disappointed…
They somehow managed to turn a beautiful, simple, intuitive, streamlined app into an extremely confusing, overcrowded messy one with a much uglier interface, intrusive “challenge” and “badge” pop-ups, features that were always free are now paid for, and just overall a terrible user experience.
Will probably be deleting after this fast is done.
-- SofiaMCF, 2023-06-11

### ***** "Zero app"
Effective very colourful and inspiring
-- Reinymartieex, 2023-05-25

### **--- "Weight log"
Can no longer log weight without linking to Apple health. If I ignore the prompt the weight screen closes before I can do anything.
-- sjajakansldmks, 2022-11-12

### ***** "Awesome app"
Started fasting a month ago and the app is helping me a lot! The paid version is worth it too but it works pretty well even without it
-- katebgs, 2022-07-25

### *---- "Thanks for fixing the interface"
After some complaints, you listened and changed the interface, removing the “premium traps” from the main buttons. 
Thank you! 🙏🏼
-- Rapha Stan, 2022-02-11

### ***** "Precious help"
Been doing my free testing I must say it helps a lot focusing in our goals. Wish I could afford the Plus version, to enhance my experience. Anyway, feel most happy with it… just could not find yet, how to turn it in portusuese. Not possible, or plus option? Thx anyway!
-- lxmiz, 2021-11-05

### ****- "Beware of updates"
Every time there is an update, the app forgets the start date and time of the fast, that is, it just resets the fast tracking. So make note of the start date/time before the update and then restart the fast after the update.
-- iPad Yes Please, 2021-03-12

### ***** "Adoro"
Intuitivo e simples. Ao mesmo tempo muito completo mesmo para quem usar a versão gratuita. Estou no meu quinto jejum e estou a adorar a aplicação.
-- the weird sistah, 2021-03-09

### *---- "bad support in a full of bugs app"
the app have a lot of bugs, specially when connecting with workout, diet, and even apple health. there’s no effective customer support. just a robot “answering” messages with generic answers. 
if you’re just looking an app for tracking your fasts, it’s ok. but if you want to compare it with any other of your results, i don’t recommend. it’s a super expensive service (only the upgrade have those connections) and doesn’t work.
-- priscilladavanzo, 2021-01-26

### ***** "Bom"
Ate agora 3 dias e tudo bem
-- Uqueheiei, 2020-12-17

### ***** "The best"
Practical, exactly what I was looking for!
-- 1DITA3, 2020-11-22
