21-dages nulstilling
Ikke endnu en streak-tæller — et indbygget 21-dages program. Fire faser, seks regler, én målstrege. Og hver regel afkrydses automatisk ud fra det, du logger, så der er ikke tale om et æreskodeks.

Regler, der afkrydser sig selv
Intet skal afkrydses manuelt. Hver regel verificerer sig selv ud fra dine måltidsscanninger, din vandlog og dine skridt — du skal aldrig selv indtaste et flueben.
Den faste regel
Vær inaktiv i en dag, og nulstillingen fryses. Afslut den næste dag for at genvinde den. To inaktive dage i træk afslutter forløbet — derfor har dag 21 en særlig betydning.
Kontrolpunkter undervejs
Vejninger på dag 1, 8, 15 og 21 viser udviklingen, og det valgfri foto fra dag 1 får sin modsvarende del på dag 21.
How it works
Calorie tracking that takes seconds, not minutes
Snap a photo
Take a picture of your meal — breakfast, lunch, dinner, snack, anything. That's literally all you need to do.
AI does the work
Calsy's AI recognizes every food on your plate and calculates exact calories, protein, carbs, and fat. Instantly.
Reach your goals
Track your daily intake, build streaks, and watch your progress. Calsy makes hitting your goals effortless.
Why choose Calsy?
The smartest way to track what you eat
Stop wasting time on manual entry
Point your camera at any meal or scan a barcode. Calsy's AI plus a 300,000+ product database means every calorie and macro is tracked — instantly.
Know your macros without the math
Protein, carbs, fat — all calculated automatically with every meal. See exactly where you stand at a glance.
Stay hydrated effortlessly
One-tap water logging with daily intake tracking. Hit your hydration goals without thinking about it.
Build habits that actually stick
Daily streaks and goals keep you accountable. Most users say Calsy is the first tracker they've stuck with for more than a week.
Scan any packaged food
Barcode scanner gives you instant nutrition info for any packaged food. No manual entry needed.
Know if your food is actually healthy
Every meal gets a Health Score from A to E. Calsy analyzes food quality — not just calories — so you know if your diet is helping or hurting your goals.
Health Score
Not all calories are created equal
Two meals can have the exact same calories — but completely different effects on your body. Calsy is the only tracker that understands this.
Grilled salmon & vegetables
520 kcal
Fast food burger & fries
530 kcal
Almost the same calories. Completely different impact.
AI-powered food quality analysis
Every meal gets a score from 0-100 and a grade from A to E. Not based on calories — based on real nutritional value.
Flags 100+ harmful additives
Calsy detects concerning food additives like nitrites, artificial colors, and preservatives that other trackers completely ignore.
Understands food context
30g of protein from salmon is not the same as 30g from a hot dog. Calsy's AI knows the difference — and scores accordingly.
Processing level detection
See how processed your food really is. Calsy classifies every meal from minimally processed to ultra-processed.

FAQ
Frequently asked questions
Just snap a picture of your plate. Calsy's AI identifies every food item, estimates portions, and calculates calories, protein, carbs, and fat — in under 3 seconds. No typing, no searching, no manual entry.
Reset 21 er Calsy s indbyggede 21-dages program. Det forløber i fire faser — “Se det” (dag 1–3), “Rengør det” (4–9), “Stram den” (10–14), “Bevis det” (15–21) — med op til seks daglige regler, såsom at scanne to måltider, nå dine mål for vandindtag og skridt, holde måltiderne over en bestemt kvalitetsgrad og holde dig inden for dit kaloriebudget. Reglerne afkrydses automatisk ud fra det, du registrerer, der er vægtkontrol på dag 1, 8, 15 og 21, og én dag uden registrering fryser forløbet – to i træk afslutter det.
Calories only tell half the story. Two meals can have 500 kcal but completely different effects on your body. The Health Score (0-100, grades A through E) analyzes food quality — protein source, fiber, sugar, additives, processing level — so you know if your meal is actually helping or hurting your goals.
Yes. Calsy automatically flags over 100 concerning additives like E250 (nitrites in bacon and hot dogs), E171 (titanium dioxide, banned in the EU since 2022), and E951 (aspartame in diet drinks). Each one is classified by risk level — so you see what's in your food before you eat it.
Other trackers make you search databases and type everything manually — that's why most people quit within a week. Calsy is photo-first: snap a picture, done. Plus it goes beyond calories with Health Score, additive detection, and food processing analysis. It's the tracker people actually stick with.
Calsy's AI recognizes thousands of foods and dishes worldwide — home-cooked meals, restaurant dishes, multi-ingredient plates, even street food. Plus, the barcode scanner gives you instant access to a database of over 300,000 verified products with exact nutritional data.
Calsy works in over 35 languages including English, Spanish, French, German, Japanese, Korean, Chinese, Portuguese, Italian, Polish, and many more. AI food recognition works across all supported languages.
