Tansei turns weight tracking, BMI monitoring and daily steps into a clear, focused routine — with just enough game to keep you coming back.
Log your current weight and set a target, so progress over weeks and months is always visible at a glance.
Keep an eye on your Body Mass Index alongside your weight, without needing a separate calculator.
Set a walking goal that fits your life and track how consistently you hit it, day after day.
Choose to focus on weight, BMI, or both — Tansei adapts the interface to the goal you actually care about.
A calm, modern dark interface built to be checked in seconds, not stared at for minutes.
Every day you stay on track earns experience — a small nudge that turns a habit into a bit of a game.
