LeanPlan: Weight Loss Planner

Zero friction. Zero registration. Just results.

Lose weight your way. No login. No ads. Total control.

LeanPlan has the simple mission of being frictionless to use. No account required. No subscription. No cloud.

TRACK CALORIES & MACROS THE RIGHT WAY

Log every meal in seconds. Search our database of thousands of foods, scan barcodes, or create your own custom recipes. LeanPlan shows your daily calorie ring, protein, carbs, and fat breakdown in real time.

SEE YOUR REAL WEIGHT TREND

Daily scale readings lie. Water weight, glycogen, and sodium can swing your reading by 1–2 kg overnight. LeanPlan uses an Exponential Moving Average (EMA) algorithm to smooth out the noise and show your actual fat loss trend over time.

CALCULATE YOUR TRUE TDEE

Most apps guess your calorie target using a generic formula. LeanPlan does it differently. By correlating weeks of your actual food logs with your real weight change, LeanPlan calculates your empirical Total Daily Energy Expenditure (TDEE). Use it to set a smarter, more accurate calorie goal.

SYNCS WITH APPLE HEALTH & APPLE WATCH

Grant optional HealthKit access and LeanPlan automatically: • Pulls your latest weight from Apple Health or a Bluetooth scale • Imports your Apple Watch active calories and adds them to your daily budget • Writes manual weight entries back to the Health app

All HealthKit data stays on your device. Always.

PLAN YOUR MEALS ACROSS THE WEEK

Set flexible calorie budgets across Breakfast, Lunch, Dinner, and Snacks. View your entire week at a glance. Spot patterns. Adjust targets. Build habits that stick.

100% PRIVATE. LOCAL-FIRST.

LeanPlan stores everything in a fast SQLite database on your iPhone. We have no servers. We see none of your data. Ever. Deleting the app deletes everything — we hold nothing.

No account to create. No email address required. No tracking scripts. No ads.
