iPhone
No ads, no account, on-device only. One-time Pro unlocks pace and goal forecast.
Your morning weight swings by a kilogram from water and yesterday's dinner. Nagi (Japanese for "calm sea") puts the 7-day moving average front and center so the noise stops deciding your mood.
■ Log in 10 seconds
A custom keypad, your last value pre-filled, ±0.1 nudges. Body fat and notes are optional.
■ See the real trend
Daily readings are faint dots; the 7-day average is one clear line. When today's reading sits far from the average, Nagi says so honestly: probably temporary.
■ Distance to goal
Change since start, remaining to goal, and progress on one screen.
■ Apple Health sync (free)
Import weight your smart scale saved to Health, and export your log back to Health.
