How it works

Three steps, then it runs forever

01
Add a moment
Give it a title, pick a date and a category. Add photos and a note if you like — it takes ten seconds.
02
Watch time flow
Every moment gets a living counter — years, months and days since it happened, always up to date.
03
Celebrate milestones
Anniversaries and round numbers like day 100 or 1000 are highlighted — with confetti when they land on today.
