The fastest days until calculator for iPhone. Count down to future events - birthdays, holidays, exams, trips - or count up from past events like anniversaries and goals. Unlimited countdowns, beautifully organised.
Countdownn's core feature lets you create a countdown timer for any future event or a count-up tracker for past events. It's the most flexible days until calculator for iPhone - whether you're counting down to your next holiday or counting up the days since an important life milestone.
Every countdown displays the number of days, hours, minutes, and seconds remaining. Set recurring countdowns that automatically reset yearly - perfect for birthdays and anniversaries. With unlimited event countdowns, every important date in your life can have its own dedicated timer.
Create your first countdown in under 30 seconds - no account, no setup, just open and go.
Search "Countdownn" on the App Store or tap the download button on this page. Open the app - no login or account required.
Tap the large + button in the top right corner or centre of the screen to create a new countdown event.
Type a name for your event (e.g. "Christmas", "Exam Day", "Bali Trip"). Tap the emoji selector to pick an icon that represents your event.
Use the date picker to select the exact date. For precise hour-level countdowns, also set the time. The countdown starts calculating immediately.
Select Count Down for future events (days remaining) or Count Up for past events (days elapsed since). Both modes work in the same app.
For annual events like birthdays and holidays, enable Recurring and choose Yearly. The countdown will automatically reset each year - set once, works forever.
Every countdown calculates the exact difference between the current moment and the target date - down to the millisecond - using the device's system clock. The display updates every second in real time.
For yearly recurring countdowns, the app calculates the next occurrence of the target date automatically. Once December 25 passes, Christmas immediately resets to next year - zero manual work.
Count Up mode tracks elapsed time since a past date - e.g. "730 days since our anniversary". The app stores the original past date and calculates days elapsed from that moment to now, updating continuously.
All countdown data is stored locally on your device using Swift's native data persistence. No internet required to view, add, or update any countdown. Pro users also get iCloud sync across devices.
Yes - Countdownn's free version supports unlimited event countdowns. You can add as many birthdays, holidays, trips, deadlines, and milestones as you want with no limit. Pro features like iCloud sync, premium widget styles, and calendar import are available as upgrades but are not required for unlimited countdowns.
Count Up mode lets you track elapsed time since any past date. For example, enter your anniversary date and choose Count Up - the app shows "730 days together" and updates daily. It's perfect for anniversaries, sobriety milestones, fitness streaks, relationship timelines, and any event you want to remember the "days since" for.
Recurring means the countdown automatically resets after the event date passes. Set a birthday as a yearly recurring event and the moment the birthday passes, the countdown immediately switches to counting down to next year's birthday. You set it once and it works automatically every year - no manual editing required.
Yes. Each countdown displays days, hours, minutes, and seconds in real time. For events where the exact time matters - like a flight departure or exam start time - set the specific time when adding your countdown and you'll see a live timer counting down to the exact moment.
