Flight number in, plan out
Any flight, any destination. It knows which direction is the hard one and how much to shift before you even leave.
One tape per day
Wake, bright light, sunglasses, last coffee, dim the lights, sleep. Every hour belongs to exactly one state.
Reminders in the right time zone
A morning brief and a nudge at every change, with the airport chime, wherever you are that day.
Live on your Lock Screen
A Live Activity that counts down the block you're in, widgets for Home and Lock Screen, and complications for Apple Watch.
Wallpapers and cabin mode
Each day's plan as a lock-screen wallpaper, dark or light. On the flight, a near-black sleep screen with both clocks.
The arrival report
When you land alert, a card worth sharing: the route, the hours shifted, the whole journey drawn as a stack of days.
