About

Uair

Features
Read full description

Uair sets a mechanical watch to the second, then keeps a record of every watch you own and how each one runs. SET IT Pick a minute and Uair counts you in. Pull the crown to stop the seconds hand at 12, set the hands to the time on screen, and wait. The last three seconds fill the screen. At zero the screen flips and the phone taps in your hand: push in the crown. That's it, to the second, against your iPhone's network time. FIVE FACES Day-Date, GMT, Moonphase, Dive and Chronograph, each drawn for its complication: the date window, a second timezone on the 24-hour hand, today's moon, the bezel, the subdials. Each one comes with a short guide to what the hands are for and how to set them. THE COLLECTION Keep every watch you own in one place: photos, reference, serial, movement, what you paid, and every service. Uair lifts each watch out of its photo and sets them all at the same size, so the collection looks like one. Then find out how it really keeps time: • Listen. Lay the watch on the phone and Uair times its tick through the microphone. A rate in seconds a day, with beat rate and beat error, in about twenty seconds. • Check the time. Tap as the seconds hand passes 12, again a day or two later. Over a few days of wear you get the rate on the wrist: every position, every temperature, the one that matters. Rates are kept run by run, so you can see a watch before and after a regulation, and which ones have started to drift. WIDGETS A watch face for the Home Screen, Lock Screen and StandBy, and a Watch rate widget that shows how one of your watches is running. PRIVATE No account, no analytics. Your watches stay on your device, photos are cut out on the device, and the microphone sound is analysed as it arrives and never saved or sent anywhere. PRICING Setting your watch, the faces and the face widgets are free, always. The Collection is a one-time unlock with a free 14-day trial. The trial ends on its own and never charges you. Unlocking is one payment, with no subscription, and Family Sharing is supported.
