Timesewn is an alarm clock, world clock, countdown and time hack that actually understands time zones. No account, no ads, no tracking. Free to download, and Timesewn Pro, one optional purchase, unlocks everything. CONVERT A TIME FROM ANY APP Someone writes "3pm EST" or "noon Tokyo on Friday"? Select it, tap Share, then Convert with Timesewn, and see that moment in your time and in each of your cities. Start a counter or set an alarm right from there. (Timesewn Pro) ALARMS IN ANY TIME ZONE Set a wake-up time in your destination's time zone and let Timesewn do the math. A live preview shows exactly when it will ring in your local time, so an early call abroad is never a surprise. Every alarm carries a label and a countdown, repeating alarms set for another city ring at that city's local time, and alarms ring even on silent, powered by Apple's AlarmKit. Traveling? When your time zone changes, Timesewn asks whether your repeating alarms should stay put or move with you. WORLD CLOCKS Live times for every place you care about, with your own time always on top. Press and hold to drag the rest into any order. Tap a city for its sunrise, sunset, working hours and next clock change, and get a heads-up a week before any of your cities switches to or from daylight saving time. Turn on the world map to see every city with the night side shaded. Type a time in plain words, like "5pm Tokyo", and see it in every city at once. With Timesewn Pro, your next calendar event shows at the top of Clocks with its start time in each city; your events stay on your iPhone. PLAN A TIME Slide the planner and every clock follows, with day badges when a city crosses midnight. Copy a city's time, or every city's at once, ready to paste into a chat. With Timesewn Pro, share the moment as a card or text, and the Overlap view lines up each city's working day so the hours everyone shares stand out, and a tap plans the meeting. COUNTERS Count down to a moment in any time zone, or count up from one that has passed, and sound an alarm at zero. With Timesewn Pro, record timestamps as you go with the gap between each one, export them as a CSV file, and start from a template: Deadline, Launch Day, Days Since, Streak or Trip. TIME HACK Set your watch to the second. The Hack tab shows the exact time from a network time server, re-synced every two minutes, and counts down to the top of every minute with a tap and a beep for the last five seconds. It shows how long ago it synced and how far off your iPhone's clock is, in your own time zone or any city you choose. ON YOUR WRIST AND YOUR HOME SCREEN With Timesewn Pro, Timesewn on Apple Watch shows your clocks, counters and alarms, with complications for your watch face, and records a timestamp with a tap. Widgets put your world clocks, a counter or your next alarm on the Home Screen, Lock Screen and StandBy. Siri and Shortcuts are there too, a Focus filter shows only the cities that matter right now, and you can pick one of four app icons. FREE, OR EVERYTHING WITH TIMESEWN PRO Free: your own clock and 3 cities, 2 alarms, 1 counter, the world map, the Plan slider, city details, Time Hack and iCloud sync. Timesewn Pro, a one-time purchase, unlocks everything marked Timesewn Pro above, plus unlimited cities, alarms and counters and Timesewn's own alarm sounds. Family Sharing is supported. If you bought Timesewn before, Pro is already yours. Catching an early flight, joining a call with another continent, keeping tabs on family overseas, setting your watch before a big day: Timesewn keeps you on time, everywhere. Made the Adventure Apps way: • Free to start, one optional purchase. No subscription, no ads. • No account, no tracking. Your alarms and calendar stay on your iPhone and Apple Watch; your clocks and counters sync with Timesewn on Mac through your own iCloud, never through us. • Small, fast, native. • In English, German, Spanish, French, Italian, Japanese and Korean.
