iPhone

Luff is now completely free. Every feature, no subscription, nothing held back. Set a goal, see your trend, get a calorie target that adapts to your real results. You keep stepping on the scale and reacting to a single number. Up two pounds, day ruined. Down one, false hope. The number never tells you whether you're heading in the right direction. Luff does. Set a goal. See your trend. Get an honest calorie target that adapts to your real results, not a generic formula. No food logging. No meal photos. No streaks. No coach trying to be your friend. Weight tracking is a small job done daily, and Luff treats it that way. Have a normal weekend without the app sulking about it. Plot a new course from where you actually are, not where you wish you were. How it works Pick a direction: lose, gain, or maintain. Step on your scale; Luff syncs with Apple Health. Hit your goal and Luff shifts you to maintenance automatically. What's included: Weight logging with Apple Health sync. A smoothed trend line instead of daily noise. Week, month, quarter and all-time views. Drift alerts when your trend leaves the corridor. Adaptive calorie targets. Goal predictions. Insights on energy balance, movement, sleep, exercise and logging consistency. Home screen and Lock Screen widgets. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
