What's New in Lean
2.0.0
September 6, 2026
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
