About this app
100! – Together we are 100!
Celebrate, remember, calculate – this app brings people together and makes big anniversaries come alive, long before anyone turns 100 alone.
Never forget a birthday again
With 100! you keep track of all the important birthdays. Parents, siblings, friends, grandparents or colleagues – the app reliably reminds you, automatically and on time, of every birthday. Thanks to smart notifications, you’ll get a reminder every morning at 10 a.m. so you’ll never miss a special day again.
Celebrate together instead of alone
Everyone gets older – but big round anniversaries come much faster when you count them together.
100! calculates when you and your family, your school class, your club, your group of friends or your team reach a shared milestone.
When will you together reach 100 years?
When will your group turn 500 years?
When will your whole family celebrate 1000 years of life?
These magical moments are the perfect reason to celebrate – far better than waiting alone for your personal 100th birthday.
More reasons to celebrate
100! shows you how quickly these milestones approach:
Siblings together soon reach 200 years.
Your soccer team adds up to 1000 years of life.
Your old school class will soon celebrate a 500-year total.
Suddenly there are so many more reasons to meet, laugh, celebrate and create memories.

Because: Celebrating 100 together is far more fun than waiting alone for your own 100th.
Family reunions, class meetups, club anniversaries or gatherings of friends – 100! gives you the perfect reason to invite everyone again.
