The app
Log, see, understand, move forward.
Four steps, four tabs. Nothing to weigh, nothing to search for in a database, and every number shows where it comes from.
See the trend, not the number of the day
Your dial for today, then your weeks: weight, energy, sleep, fasting, steps.
Understand your lab results
Take a photo of a lab report: your markers are read and tracked, with the range printed by your lab.
Move forward, one step at a time
No imposed program: one suggestion a day, tied to what you logged, which you follow or not.
The coach
A coach that starts from your numbers, and from your cooking.
Cadran doesn't give you a diet. It looks at what you logged and suggests the next small useful thing.

Questions
The questions people ask us.
Is Cadran a medical device?
No. Cadran is a personal tracking tool: it records, organizes and reminds you where each number comes from. It doesn't diagnose, doesn't prescribe, and doesn't replace a doctor or a dietitian.
Do I need to weigh my food?
No. One sentence is enough: “a chicken tagine and some bread”. Adjust the portion in one tap, or correct it in one sentence.
Is my data sold or shared?
Never sold. It is stored in Paris and is only used to make the app work. Only our technical providers (storage, AI, email delivery) receive what they need; they are named in the privacy policy. You can export your data or delete your account at any time.
Does Cadran take my allergies and practices into account?
Yes, in the recipe book and meal ideas: recipes containing what you exclude are hidden, and AI ideas are checked before they're shown. For a severe allergy, always check the ingredients.
Is there an Android app?
Not yet. On Android, Cadran works in the browser, with the same account.
What happens if I stop Cadran+?
You keep free Cadran and all your data. Your lab results stay readable and your reports viewable; only new Cadran+ content stops.
Start with one meal.
The rest follows.
Cadran is a personal tracking tool, not a medical one. Meal estimates, lab-report reading and answers to your questions are produced by artificial intelligence: they are indicative and can be wrong. Coach suggestions are calculated by fixed rules, from what you record.
