Day Counter for iOS & Android

Chronos

Count the days that matter.

Chronos shows how many days have passed since a date that matters to you: one number, in large type, on a calm dark screen. Pick the day something began, a new job, a move, the day you quit, and Chronos counts from it.

Free, with no account and no ads. Chronos Pro is a one-time purchase that adds widgets, milestone reminders, and your count in years, months or weeks.

Want a quick answer? The free online day counter counts the days since or until any date.
