TimeFeel makes time visible. Count down to the days you're waiting for — trips, birthdays, weddings, exams — or count up from the moments that changed everything, and see exactly where you stand at a glance. Countdown & Count-up Create a countdown for any event, or count up from any date. Switch between "time left" and "time passed" to see time the way you want. Repeating countdowns Birthdays, anniversaries and paydays roll over on their own. Repeat daily, weekly, monthly or yearly, or build a rule as flexible as Reminders — the second Tuesday of every month, the last day of the month — with an optional end date. Import from Calendar Pick the events you want from your calendar and turn them into countdowns in a tap. Nothing is added until you choose it. Holiday ideas Start from New Year, Christmas and other yearly dates without typing a thing. A live clock everywhere Countdown cards, widgets, the Lock Screen and Apple Watch tick in real time — days first, then hours, minutes and seconds. Open-ended timers No end date needed. Track how long something has been going — a habit, a journey, a chapter of your life — without setting a finish line. Progress at a glance Every countdown shows how much of its span has passed, as a ring or as a percentage of time done or left. Custom colors & photos Pick an accent color for each countdown. With Plus, use your own photo — it becomes a soft, blurred full-screen backdrop. Smart notifications Every countdown tells you when it ends. Add reminders a set number of days before or after, or when a percentage of the time has passed. Widgets on every screen Home Screen widgets in two sizes, plus Lock Screen widgets — a ring, or a line right under the clock. Your countdown is there before you unlock. Apple Watch The full app on your wrist, plus complications for your watch face — your next countdown sits right on the dial. Live Activities When a countdown enters its last stretch, it appears on the Lock Screen and in the Dynamic Island — photo and all — and keeps ticking there until it's done. Find any countdown Search by name and group your countdowns by year or month. iCloud sync All your countdowns sync automatically across your iPhone, iPad and Apple Watch via iCloud. Plus Unlock photo backgrounds, unlimited countdowns, advanced notifications and new app icons — monthly with a free first week, or a one-time purchase that's yours forever.

D-Day turns the dates that matter into targets on a radar. Whether you are counting down to a product launch, an exam, or a trip — or counting up the days since you started something — D-Day shows it as a large glowing readout with a live progress ring, wrapped in an authentic cyberpunk terminal aesthetic. // PRIMARY_TARGET One target is always locked as your primary and rendered front and center: • Large neon D-42 readout with a breathing glow • Circular progress ring showing how far along you are • Live DAYS : HRS : MIN : SEC countdown, updating every second • Pin any target to promote it to the primary slot // COUNT_MODES • Countdown — counts down to a date (D-7), reaches D-DAY, then keeps counting past it (D+3) • Count Up — counts the days elapsed since a date (D+120), for streaks and anniversaries • Optional time of day, so you can count to an exact moment rather than just a date // TIMELINE Every other target lines up below the primary panel: • Sorted automatically — nearest upcoming first • Progress bar and percentage on every row • Detail view with full telemetry: badge, days remaining, weeks, anchor date, progress // PERSONALIZATION • 5 neon accent colors • 12 category icons — launch, birthday, exam, work, travel, fitness, payment, celebration and more // DESIGN_SPECS • High-fidelity cyberpunk aesthetic • Monospace terminal typography with glowing panels • Progress rings, CRT scanlines, and a faint background grid • Designed dark, always // PRIVACY_FIRST D-Day works completely offline. Your targets are stored only on your device. No account, no sign-in, no network calls, no tracking, no ads. The app requests no permissions at all. Simple by design. Lock your targets and watch the numbers fall.
