## Calsy Description
Calsy is a 21-day reset for people who are done with diets that drag on forever. You get a start line, a few rules a day, and an AI that logs your meals from a single photo. On Day 21 you step on the scale and see what changed.

No food diary. No weighing every bite. No willpower marathon. Twenty-one days you can actually finish, and habits that stay with you when they are over.

HOW THE 21-DAY RESET WORKS
1. Day 1: weigh in and take your start photo (optional)
2. Every day: scan your meals, drink your water, hit your steps
3. From Day 4 the bar rises: meals graded C or better, stay under your calorie budget, 30 minutes of movement
4. Day 21: final weigh-in, second photo, before-and-after side by side

The reset runs in four phases: See It, Clean It, Tighten It, Prove It. Each one asks a little more than the last, so it gets harder exactly as you get stronger.

RULES THAT TICK THEMSELVES
Other challenge apps are checklists you have to remember to tick. Calsy already knows you scanned two meals, logged your water and walked your steps, so the rule turns green on its own. You live your day. The app keeps score.

SNAP IT. SCORE IT.
Take a photo of your plate. In seconds Calsy&#039;s AI logs calories, protein, carbs, fat, fiber, sugar and sodium, and grades the meal from A to F. One glance tells you whether it counts toward your reset. Barcode scans and Health Scores work the same way for packaged food.

WATCH IT WORK
A weight trend that smooths out the daily noise, a journal that marks every day you logged, and a line that goes the right direction. Seeing it drop on Day 12 is what gets you to Day 21.

DISCIPLINE THAT OUTLASTS THE RESET
Twenty-one days of the same small rules does something no diet ever did for you: it makes them automatic. Scanning before you eat. Drinking your water. Moving every day. Checking the grade before you order. By Day 21 you are not following rules anymore, you just eat like this. The weight is the result. The discipline is what you keep.

AFTER DAY 21
Finish Baseline and unlock Strict. Finish Strict and unlock Full. Every reset raises the bar, so your next 21 days start where the last ones ended. And between resets Calsy stays the easiest calorie counter you have used: snap, log, done.

TARGETS BUILT AROUND YOUR BODY
Lose fat, build muscle, or just eat better. Calsy sets your daily calorie and macro budget from your body, your activity and your goal. Not someone else&#039;s numbers.
