About Sixty-Six
Sixty-Six replaces the Chrome new-tab page with a simple tracker for completing one habit over a 33, 66 or 99-day run.
Choose a run of 33, 66 or 99 days, then mark each day complete as you move toward the finish line. Your current day and progress stay visible every time you open a new tab, helping you return to the habit without adding another app, dashboard or list to manage.
Sixty-Six is deliberately simple: one habit, one run, one clear finish line.
Features:
— Track one habit at a time
— Choose a 33, 66 or 99-day run
— Replace your new tab with a focused daily view
— Mark each day complete
— See your progress build over time
— Review and archive past runs
— Reset and begin again whenever you need to
— Store your habit data locally in Chrome
— No account required
Sixty-Six is designed for habits such as writing, reading, stretching, meditating, practising a language or doing one small thing consistently.
Your progress stays on your device. Sixty-Six does not require an account and does not sell your data.
