Start by adding the people and pets you want to track. Simply enter their name and birthdate, and the app will calculate important milestones automatically. You can also import from your contacts 

Want to see combined milestones for family, friends, or colleagues? Create a group by selecting two or more registered persons. The app will then calculate shared birthdays and other fun anniversaries. Any individual can be a member of as many groups as you like.

Sure, remembering your wedding anniversary is impressive—but imagine casually mentioning over breakfast that you’ve been married for 2,000 days! With Celebratus, you can celebrate not just the big milestones, but all the fun ones in between. 

Some milestones are too good to miss! Mark them as favorites to keep track of upcoming celebrations easily. These are always readily accessible on the front page.

Curious about the age gap between friends, siblings, or colleagues? Use the built-in age difference tool to compare your ages .

Worried about missing a celebration because you didn’t create a group for every friend? No problem! We automatically pair you with each registered person and suggest fun milestones you can celebrate together.

Too many celebrations? Increase the intervals for years, weeks, and days. Want more? Lower the intervals! You can even switch on planet years or dog years for a fun twist.
