Description by Ulrich Helker Written by the developer, not by AppBrain. Click to read.
Multibirthday finds the magical days when the sum of everyone's ages reaches a round number. Add up the ages of you and your loved ones – whenever the total lands on a round number (40, 50, 100 …), it's Multibirthday. A brand-new reason to celebrate that nobody else knows about.
THE IDEA
Two people have two Multibirthdays a year, three people have three, and so on. The more of you there are, the more often you celebrate together. Separate birthdays become one shared event.
FEATURES
• Calculate shared birthdays for up to 5 people
• See your next Multibirthdays at a glance – with countdowns
• Reminders so you never miss a day
• Presets for couples, family, friends & colleagues
• Save as many groups as you like
• Share your Multibirthday with a link
• Celebrity examples to try instantly
HOW IT WORKS
1. Enter names and birthdays
2. Tap "Calculate"
3. Discover your next shared celebrations
PERFECT FOR
