Kaizen - 1% Better Daily

Kaizen is the Japanese principle of continuous improvement through small, consistent change. This app applies the principle to daily habits and shows the math.

One percent better each day. Compounded over 365 days, that is 37 times the person you were when you started. The arithmetic does not lie; the discipline is in showing up.

Pick a habit. Set where you are today and where you want to be. Each morning the app sets a target slightly closer to your goal — the precise difference your math engine computes from your last logged value. Hit the target and your daily gain compounds onto every other habit you track. Miss it and tomorrow resets without penalty.

Categories cover the five domains that shape a life:

Wellbeing — sleep, fitness, nutrition, mindfulness.

Wealth — spending, saving, financial habits.

Relationships — family, friendship, presence.

Recovery — reducing what you want less of.

Growth — reading, practice, learning.

Each category compounds independently. There are no streak guilt cards, no notifications begging you back, no AI pretending to be your coach, no badges, no leaderboards. Just the number, the chart, and the work.

A habit graduates after twenty-one consecutive days at goal. The compounding gain remains in your total, the slot frees for the next thing you want to change.

Your data lives in your account. Sign in with Apple, Google, or email. Account deletion is one tap and erases everything — habits, logs, telemetry — within seconds.

Kaizen is for people who take self-improvement seriously and have run out of patience for the alternative.
