About

iCountdownClock

Features
Read full description

iCountdownClock keeps you focused on what's ahead — the vacation, the birthday, the big day you've been working toward. Set it up on your iPhone and watch your countdowns live right on your wrist or iPhone home screen. Scrollable event tiles on Apple Watch Every countdown you care about, organized as color-coded tiles you can scroll through at a glance. Blue for your featured event, purple for upcoming, green when it arrives. Always on your watch face Pin your most important event as a watch face complication — the countdown is there the moment you raise your wrist, without opening a thing. Arrival celebration When your moment finally comes, iCountdownClock celebrates with you on the watch — confetti, a custom notification, and a little well-deserved fanfare. Stress relief, done differently Most wellness apps detect low heart rate variability and tell you that you're stressed — which isn't exactly helpful. iCountdownClock does something different: when your Apple Watch senses elevated stress, it quietly reminds you of something you're looking forward to. A nudge toward optimism, not anxiety. Private by design All your data stays on your devices. Nothing is sent to any server. Pricing Free for one countdown event — everything included. Unlock unlimited events for a one-time $2.99 in-app purchase. No subscription, no recurring charges.
