Set your watch to the second. Then know how it runs.
A countdown and a tap at zero for setting it. A record of every watch you own, and how fast each one really runs, for keeping it.
Pick a minute
Pull the crown at 12 and set the hands to the time on screen. Uair counts you in.
Now.
At zero the screen flips and the phone taps in your hand. Push in the crown.
Learn it
Day-Date, GMT, Moonphase, Dive and Chronograph, with what every hand is for.
All in one place
Every watch you own, with its photos, reference, movement and service history.
Record a measurement
Measure how your watch is keeping time just by listening to the movement.
Free for 14 days
Then one payment to keep it, with no subscription. Setting your watch stays free.
Is it free?
Setting your watch, the five faces and the face widgets are free, always. The Collection is a one-time unlock you can try free for 14 days. The trial ends on its own and never charges you, and there's no subscription.
Do I need a specific watch?
No. If it has a crown you can pull, Uair can help you set it. Listen works on any watch you can hear ticking.
Where does the time come from?
Your iPhone's network-synced clock. You're matching something already right.
How accurate is Listen?
Checked against a quartz watch, the phone's audio clock agrees to about a second a day. For the rate on the wrist, check the time a day or two apart.
How do you say Uair, and what does it mean?
OO-ur. It's the Scottish Gaelic word for hour, time and o'clock. That's the whole app: set the time, then keep your watches to it.
Wasn't this called ChronoSync?
It was. Same app under a new name, and an update if you already have it.
Does it collect anything about me?
No accounts, no analytics. Your watches stay on your device, and Listen never saves or sends what it hears. The privacy note has the full story.
Go set your watch.
Then find out how it keeps time.
