How long until your wedding? Your daughter's birthday? That vacation you've been dreaming about for months? My Countdown turns every wait into something you feel, day after day. STOP COUNTING DAYS IN YOUR HEAD You know that feeling of never quite knowing how long until something important? With My Countdown, that's over. Open your phone and your countdown is right there on your home screen, with days, hours, and minutes ticking in real time. No mental math, no flipping through calendars. Just the thrill of watching that number get closer to zero. EVERY COUNTDOWN TELLS YOUR STORY Your sister's wedding isn't the same as the Super Bowl. A beach vacation isn't the same as graduation day. That's why every timer you create can look completely different from the rest. - Use your own photos as backgrounds, or browse thousands of images from the built-in gallery - Mix colors, gradients, and 7 graphic styles to create something unique - Choose from over 30 themed fonts to set the right tone for every occasion - Pick how you see time: years, months, weeks, days, or just hours and minutes It's not just a timer. It's your way of making every wait feel special. ALWAYS IN SIGHT The beauty of My Countdown is you don't need to open the app to check how long is left. Home screen widgets show your countdown in real time, in different sizes and styles. And with lock screen widgets, a quick glance at your phone is enough to smile thinking about that trip coming up or that birthday you don't want to forget. MADE FOR PEOPLE WHO KEEP TRACK OF EVERYTHING If you're the kind of person who stays on top of it all, My Countdown is for you. - Create as many countdowns as you want, with no limits - Set custom reminders to get notified days, hours, or minutes before - Birthdays and anniversaries automatically reset every year - Import events straight from your calendar with one tap - Share your countdowns with anyone you like OVER 40 READY-MADE TEMPLATES Not sure where to start? Pick from over 40 templates ready to go. Whether it's Christmas, New Year's, Halloween, Thanksgiving, a concert, prom, or the birth of a child, you'll find the perfect template with colors and styles made for every occasion. Customize it your way and your countdown is ready in seconds. IT ALSO COUNTS THE TIME THAT'S PASSED My Countdown doesn't just look ahead. You can use it in reverse too: how long have you been married? How many days since you reached a milestone? Every important moment deserves to be remembered, forward and backward. START NOW Your first countdown is one tap away. Pick a date, make it yours, and you're all set.
