Some things are worth counting down to. Dayception turns the dates that matter — birthdays, trips, launches, anniversaries, the big day — into beautiful countdowns you'll actually want to look at. Counted in sleeps, with a live timer ticking to the second as the day nears, on your iPhone, iPad and Mac. Most countdown apps stop at "days until." Dayception keeps going. THE INSIGHTS ENGINE Under every countdown is a real analytics engine that reads the shape of your year. See where your months cluster on a year heat-map. Get smart cards that surface what's coming — the next milestone, your busiest month, your longest countdown. Break the year down by category. And flip a date you've passed into a count-up, to mark the time since it mattered. ON EVERY SCREEN - Widgets for the Lock Screen and Home Screen — and they show in StandBy - A live countdown in the Dynamic Island and on your Lock Screen - A countdown that lives in your Mac menu bar, always a glance away - Siri and Shortcuts: "how many sleeps until my holiday?" - Reminders that build as the day nears: a month out, a week out, the night before, the morning of THE DETAILS - Recurring birthdays and anniversaries roll over on their own - Working-days-until, aware of UK and US holidays - Sort by soonest, pin what matters to the top, archive what's done - Turn any countdown into a beautiful card for Stories or Messages in a single tap PRIVATE BY DESIGN Dayception is offline-first. Your countdowns live on your devices and sync only through your own private iCloud — no account to create, nothing stored on our servers, and no analytics, ads or trackers. Ever. PAY ONCE Five countdowns are free, for as long as you like. Unlock unlimited countdowns and the full insights engine for a single price — no subscription. During the launch window it's £14.99 as a Founder, which also gets you an exclusive Founder app icon and a Founder badge in the app. Made for people who like to anticipate.
