Fasting
Pick a schedule or set your own. The timer shows which stage your body is in, not just how many hours have passed.
New in 3.0: a daily coach and a weekly Autopilot
Your health. One app. Powered by AI.
Fasting, nutrition, hydration, activity, sleep and recovery live in six different apps for most people. Daymons keeps them in one place — turns them into a single score you can act on, and plans your day around it.
The fasting timer counts on your device, not on a server. It keeps running on a plane, in a tunnel, with mobile data switched off.

AI insight Your body is balanced today. Focus on sleep quality to lift recovery.
Six habits. One score.
A number on its own tells you very little. Daymons watches six areas that pull on each other — a short night shows up in tomorrow's hunger, a long fast shows up in your recovery — and gives you one score with the reason behind it.
Nutrition
Log meals by search or barcode. Calories, protein and the other macros add up on their own, so the eating window has a shape rather than a guess.
Hydration
A daily goal and two taps to reach it. Water is the habit that slips first during a fast, and the easiest one to fix.
Activity
Steps and workouts, read from Apple Health or Health Connect where you allow it, entered by hand where you don't.
Sleep
Duration and consistency. Sleep is the input that moves the score the most, and the one people track the least.
Recovery
What the other five add up to. Recovery is where a hard week becomes visible before you feel it.
Daymons is a habit and wellness companion, not a medical device. The score, the stage estimates and the calorie figures are informational, they vary from person to person, and they are not medical advice. Talk to a doctor before making a significant change, and especially if you are pregnant or breastfeeding, or living with diabetes or an eating disorder.
Don't adapt to the app. Daymons adapts to you.
Version 3.0 does more than record. It learns from your own log, plans your day in the morning and your week on Sunday, and speaks up when there is a reason to. What you accept is always your call.
Daily AI coach · Premium
A plan in the morning, a review at night.
In the morning you get a short plan built from your goals, your goal programme and yesterday's log. In the evening the coach looks over the day, tells you what went well, and already prepares tomorrow's plan.
- Habit insights from your own log — which day fasting is hard, when water falls behind
- A personal weekly challenge, set just above your own average
- No medical advice — health complaints are referred to a doctor
A day with the coach
- Morning. Today's focus: water, protein, movement and the fasting window.
- During the day. The Today tab shows how much is left.
- Evening. A review of the day and tomorrow's plan, from a single request.
- Reminders. Morning and evening if you want them, scheduled by your phone.
Health Autopilot and weekly Autopilot · Premium
It keeps an eye out. Once a day, not every minute.
Once a day, the Health Autopilot looks at your trends over several days against your own average. If your nights have been getting shorter or protein keeps falling short, it sends at most one notification — and your coach's plan for the next day already takes it into account.
- You switch it on, and you can switch it off at any time
- A daily check, not real-time monitoring — and not a diagnosis
- It starts only after you have consented to the AI features
The Sunday plan for your week
- Fasting rhythm. For the week ahead, matched to your programme.
- Weekly goals. Water, movement and a sleep focus.
- The week's menu. From the recipes, with the weekly shopping list.
- A weekly challenge. Picked from your log.
- Accept or Modify. Nothing changes until you approve it.
“What should I eat?” · Premium
Photograph your fridge. We'll tell you what fits today.
From a photo of your fridge, a menu or a buffet counter, Daymons recognises what you can choose from and suggests two or three options for the calories and protein you have left today, within your fasting window. If a recipe in the library fits, you see that too.
- Correct the recognised ingredients and the suggestions follow
- The photo is used for the analysis only and is not stored anywhere
- Calories and protein are estimates — especially from a menu, where the portion is invisible
What the suggestion weighs up
- Calories left today. Not a generic daily number.
- Protein still missing. Measured against your daily goal.
- Your fasting window. And your goal programme.
- Your log stays yours. Only what you approve is added to it.
Free
Save My Day
If your day is slipping at 5 pm, you get three short tasks: water, a walk, a protein-rich dinner or the evening fast. Whatever you log ticks itself off, and a shareable #SaveMyDay card waits at the end.
Free
My story
30, 90 and 365 days on one page: completed fasts, your best streak, water, protein and workout days, your tree. Shareable as an image — without your name, and without your weight unless you switch it on.
Free · AI tuning in Premium
Goal programmes
Five programmes, such as weight loss, muscle building or maintenance. Each suggests calorie and daily protein goals and a fasting rhythm, and puts matching recipes first. New badges for water, movement and protein.
Free
Smart reminders
Water in the afternoon, protein in the evening, your streak when it is at risk — only when today's log gives a reason. At most three a day, never between 10 pm and 7 am, timed to your habits and scheduled on the device.
Free
Shared challenges
Start a challenge in your group: water, movement, fasting or protein, for one or two weeks, with live standings. From templates, no free text — the group sees your count, never your log.
Premium
Progress photos
Now and 30 days ago, side by side. Tied to your account and stored in the EU, visible only to you, never sent for AI analysis, and deleted with your account.
The Autopilot works on a daily rhythm, not in real time: our server checks your trends once a day and sends at most one notification. Suggestions from the coach, the Autopilot and “What should I eat?”, and all calorie and protein figures, are informational estimates and not medical advice. Every AI feature starts only after your explicit consent, and can be switched off at any time in your profile.
Fasting
Start it and forget it. The app does the counting.
Choose 16:8, 18:6, a longer fast, or set your own target. Forgot to start it? Move the start time afterwards and the log stays honest.
- Milestone notifications at each stage, scheduled on the device
- Works with no signal — the elapsed time is computed locally
- A streak that survives a missed day without shaming you for it
What happens, and when
- 0–4 h · Digestion. The last meal is still being processed.
- 4–8 h · Blood sugar settles. Insulin starts to fall.
- 8–12 h · Glycogen drops. The liver's sugar store runs down.
- 12–16 h · Fat burning. Fat stores take over as fuel.
- 16–24 h · Ketosis. Ketones rise, cell recycling begins.
- 24 h+ · Autophagy. The cellular clean-up steps up.
AI assistant
An assistant that has actually read your log.
Ask why the last two days felt harder, or what to eat when the window opens. The assistant answers with your own numbers in front of it — the current fast, your streak, today's score.
- Personal milestone messages, written when you start a fast
- A weekly review: what went well, what slipped, one thing to try
- Nothing is sent before you give your explicit consent
- It will not give medical advice, and it says so when you ask for it
Where the limits are
- No diagnosis, no treatment. Health complaints are answered with one instruction: stop and see a doctor.
- No fast over 48 hours and no daily target under 1200 kcal are ever suggested — not even on request.
- Pregnancy, breastfeeding, diabetes, eating disorders lead to a doctor, not to a plan.
Nutrition & hydration
Log a meal in seconds, not in a spreadsheet.
Search the food database, scan a barcode, or save your own item once and reuse it. Water takes two taps, with a reminder if you want one.
- Barcode lookup with an offline cache, so a repeat scan is instant
- Calories, protein and macros per meal and per day, against your own protein goal
- Personal recipe suggestions, with a daily or weekly shopping list
Built for real days
- Offline first. Everything you log is stored on the device and synced when there is signal.
- Nothing is mandatory. Track one habit or all six; the score works with what it has.
- Your data is yours. Export or delete your account from inside the app, at any time.
Progress
See the shape of a month, not just today.
Streaks, completed fasts, weight trend and a calendar where every day carries its own summary. Badges mark the milestones that took effort.
- A weekly AI review on the statistics tab
- Weight tracking with a goal, a trend line and a forecast — an estimate, not a promise
- Family and friend groups, with shared challenges and a live view of who is fasting
Groups, kept small on purpose
- Invite by code. Six characters, no link infrastructure, nothing public.
- Up to 20 members. Built for a family, not for a feed.
- Moderation from day one: report, block and delete are all in place.
The app, as it ships.
Not renderings. Every screen below is a screenshot of the current build, taken on an iPhone, with a real week of data behind it.
The assistant
Ask in plain words, get an answer with your numbers in it.
The question goes in as you would say it out loud. What comes back is written against your own log — the fast that is running, the streak behind it, today’s score.
- Personal milestone messages, written when a fast starts
- It stops at medical questions and sends you to a doctor
Stats
Eight days running. Twelve at your best.
The streak, the completed fasts, the average length and the last fourteen days, each bar a day. The one in orange is a fast that was broken — it stays on the chart.
- A broken fast is recorded, not hidden
- Weight trend underneath, with the change since you started
Health data
Your steps and heart rate, next to the fast.
Connect Apple Health or Health Connect and the day fills itself in. The averages count only the days that actually have data, so a missed sync does not read as a lazy week.
- Read only — the app never writes back to Health
- Sleep and workouts land in the journal on their own
Groups
Four people, four timers, one thread.
Everyone’s running fast is visible at the top, live. Below it a conversation that stays between the people in the group — invited by a six-character code, never by link.
- Up to 20 members: built for a family, not for a feed
- Report, block and delete were there on day one
Meal log
955 of 2263 kcal, with the macros underneath.
Search the database, scan a barcode, photograph the plate, or type it in. The daily target comes from your own profile, and you can override it.
- Protein, carbs and fat totalled for the day
- The estimate is labelled an estimate, right on the screen
Recipes
A menu that matches the number the app just worked out.
Breakfast, lunch, dinner and a snack, sized to your estimated energy need. The same day always gives the same menu — which is the only reason a shopping list is worth having.
- One shopping list built from the day’s menu
- Tick off what you already have at home
Health data, handled carefully.
Sleep, weight and heart rate count as special category data under the GDPR. That is not a marketing line for us, it is what shapes where the data sits and who can reach it.
Stored in the EU
Your data lives in European data centres, and is only readable by your own account. Progress photos too.
No selling, no ads
We do not sell your data and we do not run advertising against it.
AI only with consent
No AI feature sends anything until you allow it, and never your name or e-mail. Meal and fridge photos are not stored.
Delete means delete
Deleting your account removes your data and your progress photos from the server, from the app.
A better you, every day.
Daymons is out on iOS and Android. It starts as a guest, with no sign-up — and if you create an account later, everything you logged comes with you.
iOS 15 or newer, and Android.
Questions
Do I need an account to start?
No. Daymons opens as a guest and the timer starts straight away. Create an account whenever you like and everything you have logged so far moves across with you.
Does the timer work without a connection?
Yes. Elapsed time is calculated on your device from the moment you started, so a flight, a tunnel or an empty data plan changes nothing. The server only syncs; it never drives the clock.
Does Daymons watch my health in the background?
Once a day, not in real time. A phone app cannot run continuously in the background, so the Health Autopilot runs on our server once a day, compares your trends over several days with your own average, and sends at most one notification. Smart reminders and Save My Day are scheduled on your phone in advance and cancel themselves when the goal is met — no connection needed. None of it is a diagnosis.
Which languages does Daymons speak?
Hungarian, English and German. The app follows your device language and you can switch it at any time in your profile; your data is the same whichever you pick.
What does the AI see?
Only what each feature needs, and only after you have given explicit consent. The assistant sees your question and a short summary — the current fast, your streak, today's score. The coach gets today's totals, your goals and your programme. “What should I eat?” gets the photo and what is left of today's budget, and the photo is not stored. Your name and e-mail are never sent. The AI features are premium because every answer has a real cost.
Who can see my progress photos?
Only you. They are tied to your account and stored in the EU, no other user can reach them, and they are never sent for AI analysis. Delete any photo at any time; deleting your account deletes them all. A photo is shared only if you choose to, and your weight is not on the image by default.
Can it give me medical advice?
No, and it is built not to. It will not diagnose, will not recommend treatment, and will not suggest a fast over 48 hours or a daily intake under 1200 kcal. If you describe a health complaint, it will tell you to stop and see a doctor.
Does it connect to Apple Health or Health Connect?
Yes, if you allow it. Steps, heart rate, sleep and workouts can be read in, so you do not have to log twice. Permission is yours to give and to take back.
How do I delete my data?
There is a delete option inside the app. It removes your account and the data belonging to it, including your progress photos, from the server. You can also export your log before you go.
