100 days, sober & anniversary
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Reasons to celebrate, found for you — day 1,000, repdigits, even your 100-millionth second. Delivered each morning.
Reasons to celebrate, on ordinary days.
This app does more than count days.
Day 1,000 since you started dating. Your 100-millionth second alive. Day 777 without a cigarette.
Unbirthday finds the days worth celebrating — automatically — and delivers them the morning they arrive.
Plenty of apps can count.
None of them could find you a reason to celebrate.
