The Problem
Standard fitness apps use static, 100-year-old math to guess your calorie targets. They punish you for enjoying a weekend. Calibrate fixes the math and fixes the psychology.
Why Calibrate is different
Three things no other
nutrition app does.
AI Frictionless Logging
Kills the friction.
Text, photo, or barcode. The AI resolves the meal, scales the portion, and returns verified macros before you close the app.
Weekly Bank
Fixes the psychology.
A Monday–Sunday ledger banks the calories you save mid-week for the weekend. One heavy meal is not a failed week.

Method · 01
The 14-Day TDEE Engine
Every morning weight and every logged calorie feed a rolling 14-day energy balance model. We solve for your actual burn — not a formula's guess based on age, height and gender.
Δbodyweight × 7,700 kcal/kg ÷ days + mean daily intake = True TDEE
Method · 02
The Weekly Bank
A fixed Monday–Sunday ledger. Under-eat by 200 kcal on Tuesday, that credit is available on Saturday. The weekly target is the truth; the daily target is a suggestion.
Sum(daily targets) − Sum(daily intake) = bank balance available this week
Method · 03
Micronutrient Intelligence
15 nutrients — iron, zinc, magnesium and twelve more — computed from a 10,000+ item Indian food database and surfaced on a rolling 7-day saturation view so you catch deficits before they compound.
7-day trailing sum ÷ 7 × RDA = saturation %
Questions
The short answers.
How is True TDEE different from what MyFitnessPal shows?+
Standard apps use static BMR formulas (Mifflin-St Jeor, Harris-Benedict) that were derived from small population studies decades ago. Calibrate solves for your actual burn from a rolling 14-day window of your real weight and intake. As your metabolism shifts, your target shifts.
Do I have to eat exactly to my daily calorie target?+
No. The Weekly Bank is the primary ledger — Monday to Sunday. Credits and debits carry across days so a heavy Saturday doesn't undo a controlled week.
Will the AI logger work for Indian food?+
Yes. The database is Indian-first — 10,000+ items covering regional preparations, packaged brands, and street-food staples — with barcode scanning for verified nutrition panels.
Is my data private?+
Row-level security on every table. You own your data. We never sell it. Delete your account and everything goes with you.
How much does it cost?+
Early access is free while we're in beta. Pricing will be announced before we exit beta and existing users will be grandfathered.
