Relationships
From the first date to your 10th anniversary. Shareable across distance.
Milestones only you can experience.
Today is something special — even when you didn't know.
seit. counts both ways and automatically discovers the rare number-moments of your story. Palindromes, repdigits, round days, anniversaries, Fibonacci. For couples, family, travel — and yourself.
Other apps count forward. seit. counts differently.
Countdown apps know when your birthday is. seit. knows you've been together for exactly 222 days today. Or that your wedding is exactly 1001 days away. These are moments nobody else computes — we do it in the background and nudge you.
These numbers become occasions.
For every event we track several categories. You choose what to surface.

Drop a photo. Drop a date. Done.
Create an event — your first date, the birth of your child, the day you quit smoking. seit. takes it from there.
Every morning you see what's special today. On your home screen. In a widget. On your lock screen. And for the truly special days there's a card for your Apple Wallet.
For every moment that counts.

Births, first days of school, the day the dog moved in.
