Lean is law: Bulk & Cut
Adaptive TDEE & Macro Tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Lean bulk or cut? Lean is law shows your trend instead of scale noise, plans phases with a pace and, with Pro, calculates your adaptive TDEE and macros.
Run your lean bulk and cut by your trend, not by the noise on the scale.
Plan phases with a pace: Bulk, Cut, Maintain and Diet Break, each with a weekly rate in percent of your body weight.
With Pro, Lean is law calculates your adaptive TDEE from your intake and your trend and sets calories and macros for your phase.
TREND INSTEAD OF SCALE NOISE
• Trend weight, weekly rate and 7-day change instead of daily swings from water, salt and meals
• Choose the method: exponential smoothing, 7 or 14 day average or double exponential
• History with chart, daily values and phase bands
PHASES WITH A PACE
• Bulk, Cut, Maintain and Diet Break, one active phase and the next one planned ahead
• Pace in percent of body weight per week, with a warning when a bulk runs faster than 0.5 % or a cut faster than 1.0 % per week
• Maintain and Diet Break with a corridor around your weight
• Optional end date and target weight for every phase
CALORIES AND MACROS
• Log calories, protein, carbs and fat in seconds, with your recent entries at hand
• Read them from Apple Health and write your own entries back if you like
• Adaptive TDEE (Pro): your average intake of the last 14 days, corrected by what your trend did
• Target calories and macro targets for your phase (Pro), protein adjustable from 1.6 to 2.4 g per kg
HONEST NOTE: NO FOOD DATABASE
Lean is law has no food database and no barcode scanner. Take your calories and macros from Apple Health, for example from the food tracker you already use, or enter them yourself in a few seconds.
SUPPLEMENTS AND CHECK-IN
• Supplement reminders with a "Taken" action and a daily check-off
• Weekly check-in with posing photos: front, back, side and lat spread, plus weekly average, rate, waist and a note
• Progress photos stay on your device
