Age Calculator & Birthday

Never forget an important birthday again.

Age Calculator – Birthday Reminder helps you track birthdays, calculate ages, receive timely notifications, and plan thoughtful gifts for the people—and pets—who matter most.

See upcoming birthdays at a glance, organize everyone in one place, and use Home Screen widgets to check who is celebrating next without opening the app.

Stay ahead of every birthday

View upcoming birthdays over the next 30 days, see how old each person will be, and follow a clear countdown to the big day.

Smart birthday notifications

Choose when you want to be reminded:

One week before
Three days before
The day before
On the birthday

Set your preferred notification time and give yourself enough time to prepare, make plans, or buy a gift.

Home Screen birthday widgets

Keep upcoming birthdays visible directly on your Home Screen. Quickly check names, dates, and countdowns whenever you unlock your iPhone.

Track people and pets

Save birthdays for family members, friends, children, colleagues, dogs, and cats. You can also add a birthday without entering the birth year when the exact age is unknown.

Age calculator and birthday countdown

Automatically calculate each person’s current age and see how many days remain until their next birthday.

Gift ideas and personal notes

Save gift ideas before you forget them. Add personal notes, organize active gift ideas, and keep a record of past gifts to avoid repeating the same present.

With a clean, elegant design, the app makes birthday planning simple and organized.
