Dark
Inspired by the Japanese philosophy of keizoku wa chikara nari (perseverance becomes strength), Keizoku strips habit tracking down to what actually matters: showing up consistently, in a space that feels good to open every day.
No complicated dashboards. No pressure if you miss a day. Just a calm, paper-like grid where you track your daily habits and watch your momentum grow. Available in 39 languages on iOS and Android.
