A birthday comes once a year. 100 Days counts the days from a date that matters to you and turns every hundred into a fresh reason to celebrate.
There are 365 days in a year — that's day 100, 200, and 300. Three little celebrations instead of one. And the same for every event you add.
What the app does:
- Counts days from any date: a birthday, a move, the start of a habit, an anniversary
- Shows the next round milestone — 100, 200, 300 days, and so on
- A progress bar to the next milestone so you can see how much is left
- Countdown to a calendar anniversary
- Countdown to a future date for planned events
- Reminders about an upcoming milestone (optional, off by default)
- An emoji icon for each entry, with keyword search
- Light, dark, and system themes
- Export and import entries as CSV
Who it's for:
- Parents — track how many days old your little one is, no need to wait for the first year
- Anyone starting or quitting a habit — 100 days smoke-free sounds solid
- Couples — count the days together, not just anniversaries
- Anyone who launched a project, moved, or started something new
What the app does NOT do:
- No sign-up or account required
- No internet needed — everything works offline
- No ads
- No data collection: entries stay on your device only
Settings you can turn on or off:
- Intermediate milestones (200, 300, 400…)
- Countdown to anniversary
- Countdown to date
- Reminders
The app does one simple thing and tries to do it carefully. If something is missing or doesn't work as expected, leave a review — we read them.
