## What is Lean?

Snap a photo of any meal — Lean's AI counts the calories and macros in seconds. No searching food databases, no weighing, no barcodes, no typing.

Then Lean goes further than any calorie counter: it explains WHY your weight changes — not just that it did. And you can ask it anything.

HOW IT WORKS
• Point your camera at your plate → AI estimates calories, protein, carbs & fat
• One tap logs it to your daily calorie budget
• Step on the scale each morning and log your weight in 10 seconds
• Lean syncs your steps, sleep and burned calories from Apple Health automatically
• Your AI coach connects the dots: "You're up 0.4 kg, but you slept 5 hours and had 3,100 mg extra sodium — that's water, not fat."
• Ask your coach a question any day — "why am I stalling?", "what should I eat tonight?" — and get an answer built from your real numbers

WHY LEAN WORKS
Most apps show you numbers. Lean interprets them. Weight fluctuates daily for reasons that have nothing to do with fat — Lean's coach knows your sleep, steps and meals, so it can tell the difference and keep you steady through plateaus.

Setup takes two minutes and asks what actually trips you up — cravings, late-night eating, diets that didn't stick before — so your plan fits your life from day one.

STAY ACCOUNTABLE
Invite a friend to Lean, cheer each other on, and join community challenges for streaks, steps and consistency. Streak Shield covers a day you miss, so one slip doesn't undo weeks of progress.

## Version history (last 5 releases)

### 2.0.0 — 2026-09-06

The Program — your personal 11-week coaching journey
Lean now builds you a week-by-week plan from your onboarding answers: your biggest challenge, your dieting history, what actually drives you. Every week has a short lesson, one thing to practise, and a reflection at the end. Week 1 is free for everyone.

A redesigned Coach
The Coach tab now opens on Today’s Focus — the single most useful thing to do today, drawn from your real data. Every Sunday you get a recap of your week, and Coach reaches out when it notices a rough patch (“Rough weekend? Let’s reset.”).

Commitment Contracts
Name one specific commitment each week — log every day, stay under your calorie target, no late-night eating — and Lean scores how you did. Your track record builds week over week.

Clearer weight & progress charts
The weight log and trend charts are redrawn so your direction is easier to read at a glance.

Fixes & polish
• Your weight history now rebuilds itself from Apple Health if it ever goes missing, and cloud backup is more reliable
• Fixed the logging streak dropping a day it shouldn’t have
• Fixed the screen after onboarding, and a milestone celebration that could get cut off on small phones
• Faster, steadier AI coach
• Full French, German, Polish and Lithuanian translations across all the new features

More for free users
• Today's meal plan — breakfast, lunch, snack, and dinner — is now free, with protein and calories for every meal
• A fresh AI insight every week, on the house
• A clearer first-run experience that shows your projected goal date and milestones up front

Smarter meal plans
Every meal now shows protein, carbs, and fat mapped to your daily target, plus a recommended protein goal, snack options, and a one-tap swap when you want variety. Go Pro for the full 7-day plan and grocery list.

A better trial
Start your 7-day trial and we'll walk you through everything it unlocks — your first personalized coach read, meal scanning, and your goal forecast.

Plus performance improvements and bug fixes throughout.
