Simple way to change your life

The One isn't another long list of goals. It has exactly two.
The white square is one small thing you add to your life: a page of a book, five squats, a glass of water in the morning.
The black square is one thing you give up completely: sweets, cigarettes, the endless feed.
Every evening you mark both squares. A hundred days in a row.
HOW IT WORKS
• Small steps. The action should be so easy you can't skip it.
• Your streak grows only when both squares are closed.
• Five lives per hundred days. Miss a square and you lose a life, and your streak starts over. Lose all five and the hundred days start again.
• Change your goals any time: your streak and closed squares stay.
• An evening reminder if you forgot to mark the day.
• Your best streak and every square you've closed, in your profile.
You can start without an account. To keep your progress and see it both on your phone and at the-one.my, sign in with Apple, Google or email.
No ads, no trackers.
• Smoother everywhere: the confetti, shading a day and switching tabs no longer stutter.
• A new name: The One — Discipline & Habits.
