The birthday countdown app that reminds you to actually do something
Most countdown apps just show you a number. Birthday Reminder counts down to every birthday, then reminds you in time and helps you send a greeting before the moment passes.
Free on web, iOS, and Android. No ads, no paid tier.

A countdown is only useful if it
leads to something
Plenty of birthday countdown apps stop at the number of days left. Birthday Reminder shows you the countdown for every birthday and event, then does the two things a countdown can't: reminds you at the right moment, and gets a greeting ready to send.
Everything a birthday countdown app should do
A live countdown for every date you add, a widget that keeps the nearest ones in view, and a reminder that turns the last day into a greeting.
Countdowns at a glance
Live countdowns for everyone you track
See days remaining for each person at a glance — “Today,” “in 3 days,” “in 16 days” — sorted automatically so the nearest birthday is always on top.
- Countdown for birthdays, anniversaries, pets, and custom events
- Automatic sorting by nearest date
- Age shown automatically when the birth year is known
On your home screen
A home-screen widget that counts down on its own
Keep the next three countdowns one glance away, right on your home screen.
- Name, date, and days remaining at a glance
- Updates on its own — no need to open the app
- Tap a name to jump straight to their profile
From countdown to greeting
Turn the countdown into a greeting
When the countdown reaches the day, the reminder opens your messaging app with a friendly, editable message ready to send.
- Pre-filled template: “Happy birthday, [Name]! 🎉”
- You always review and send it yourself — never auto-sent
- Mark as done or snooze right from the reminder

Frequently asked questions
Common questions about birthday countdowns, reminders, and the home-screen widget.
What is a birthday countdown app?
A birthday countdown app tracks how many days remain until someone's birthday and shows that countdown at a glance. Birthday Reminder goes a step further, pairing the countdown with reminders and a one-tap way to send a greeting when the day arrives.
How does a birthday countdown app remind you before the day arrives?
A good countdown app lets you set a lead time — for example, 7 days before and on the day — and sends a reminder through push, email, or SMS/WhatsApp at a time you choose, in your own timezone.
Can a birthday countdown app track more than one person?
Yes. Birthday Reminder shows a countdown for every birthday, anniversary, pet, or custom event you add, automatically sorted so the soonest one appears first.
Is there a widget that shows the countdown without opening the app?
Yes. The home-screen widget shows the next three countdowns — name, date, and days remaining — and updates on its own.
Can family members see the same countdown together?
Yes. Shared lists let family or friends add and manage birthdays together, while each person keeps their own reminder settings.
Is Birthday Reminder free to use as a birthday countdown app?
Yes. It's free on web, iOS, and Android, with no ads and no paid tier.
