Every milestone, automatically calculated
To Us turns birthdays, ages, and relationships into a timeline full of surprises you never knew existed.
People & Relationships
Add family members, friends, and partners. Define parent-child bonds, partnerships, and friendships — each relationship unlocks unique milestone types you can't get anywhere else.
Thousands of Milestones
Birthdays, days alive, combined family ages, times-as-old moments (when a parent is exactly 2x their child's age), relationship anniversaries, and "longer together than without" — all calculated automatically.
Rarity System
Five tiers from Common to Legendary. Everyday birthdays are Common, while a times-as-old moment or a family reaching 10,000 combined days is Legendary. Each tier has its own visual presentation.
Never Miss a Celebration
Get push notifications the day before a milestone. Filter by rarity so you only hear about the celebrations that matter most to you.
Share & Add to Calendar
Share beautifully designed milestone cards with family and friends, or export any milestone to your calendar as an event so you never forget.
Available in 6 Languages
Fully localized in English, Dutch, German, French, Spanish, and Greek. Every milestone description, notification, and interface element — translated.
Five tiers of wonder
Not all milestones are created equal. The rarer the moment, the more a reason for a celebration.
