The 21-day reset
Not another streak counter — a built-in 21-day program. Four phases, six rules, one finish line. And every rule checks itself off from what you log, so the honor system isn't part of it.

Rules that tick themselves
Nothing to check off by hand. Every rule verifies itself from your meal scans, your water log and your steps — you never self-report a checkmark.
The hard rule
Go silent for a day and the reset freezes. Finish the next day to buy it back. Two silent days in a row end the run — that's why Day 21 means something.
Checkpoints on the way
Weigh-ins on Days 1, 8, 15 and 21 track the trend, and the optional Day 1 photo gets its other half on Day 21.

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.

“Calsy completely changed how I track food. I quit MyFitnessPal twice before — typing every meal was the killer. With Calsy I take a picture and the AI handles it. Three weeks in and I haven't missed a day.”
Sarah Mitchell
Marketing manager · London, UK
“I've tested every calorie counter as a coach for my clients. Calsy is the first one I recommend without hesitation in 2026 — the photo AI works on real plates, not just stock photos, and the Health Score finally gives them food-quality feedback.”
James Romero, CSCS
Strength coach · Austin, TX
“I'm an RD and I'm cautious about apps because most of them oversimplify nutrition. Calsy's additive flagging and processing-level scoring is genuinely useful patient education — it shows clients why two 500-calorie meals can be totally different.”
Emily Kowalski, RD
Registered Dietitian · Chicago, IL
“Down 11.5 kg in 4 months. The streak feature kept me logging on the days I didn't want to. Photo AI handled the hard meals — restaurant food, multi-ingredient plates — that I used to skip logging entirely.”
David Lindqvist
Software engineer · Stockholm
“Three kids, two jobs, no time to type a meal into a database. Calsy is the only tracker I've kept past week one. I scan barcodes for groceries, photo-log everything else. Done.”
Maria Garcia
Architect, parent of 3 · Madrid
“I went MFP → Lose It → Yazio → Cronometer over three years. Calsy stuck because snapping a photo costs me three seconds. Six months in, daily streak unbroken.”

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 is Calsy's built-in 21-day program. It runs in four phases — See It (Days 1–3), Clean It (4–9), Tighten It (10–14), Prove It (15–21) — with up to six daily rules like scanning two meals, hitting your water and step targets, keeping meals above a quality grade, and staying inside your calorie budget. Rules check themselves off from what you log, weigh-in checkpoints land on Days 1, 8, 15 and 21, and one silent day freezes the run — two in a row end it.
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.
