100 Days: Party all milestones

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.
