Nanotime: Server Time Clock

Ticket sales and class registration open on the site's server clock, not on your phone's clock.
Nanotime reads what time the server of a ticketing or registration site says it is, and shows it to 1/100 of a second.

■ That site's server time, as it is
Your phone clock and standard time can be hundreds of milliseconds off from a site's server clock. Even if everyone taps by the same standard time, each site opens at a different moment. So Nanotime measures the clock of the site you chose and shows that, not standard time. This is the time to count down by right before tickets drop.

■ It shows the error, too
It shows how accurate the clock is right now as ±ms. If the value gets old or the server clock wobbles, the clock dims and the error widens, so you can tell at a glance. Tap the error line to see the details of the current sync.

■ Syncing takes care of itself
When the opening is far off it syncs lightly, and as the exact moment gets close it measures more often. At the busiest moment it sends no requests to the site. You can also choose the sync intensity in Settings.

■ Ticketing, shows, sports and registration sites in a list
Pick from categories: concerts and musicals, baseball and sports tickets, university class registration, shopping and limited drops, character goods, lodging and first-come sign-ups, and overseas sites. Search by name or address, or type in an address that isn't on the list. Star a site to keep it in Favorites. Overseas sites are set to that country's time.

■ Everything on one Home screen
The server time of the site you're watching, the time left until opening and your upcoming reservations are all on one screen. Need a bigger clock? Open it full screen.

■ The exact moment, in sound and vibration
Set a target time and the time left shows in big numbers. A few seconds before, it ticks every second (choose 5, 10 or 60 seconds), and at the exact moment your chosen alarm rings, so you know without looking. Pick from 28 alarms like an alarm clock, a school bell or a fanfare. Use it as is whenever you need a timer for tapping on the dot.

■ Countdown even while you use other apps
When you switch to the booking page, Nanotime keeps counting down in the background and still plays the signal at the exact moment. It only runs this way within two hours of the target, to save battery.

■ Reserve and get reminded
Reserve opening times and get an alert at the time you set for each one. Choose how many minutes before for each reservation, and turn off alerts you don't need. Set tonight's concert and tomorrow morning's class registration together and you'll be reminded in turn.

■ Practice ticketing with Rehearsal
Make an opening 10 seconds from now on the real server time and practice. You're scored by the moment your click reaches the server, not the moment you tapped, so you get a feel for when to tap for real.

■ Use it for
Idol concert tickets, musicals and plays, opening games, university class registration, limited sneakers and goods drops, lodging and campsite booking: anywhere that opens on the dot, check the server time first. It works the same for first-come deadlines like exam registration and public facility booking.

■ Easy on the eyes
Light and dark screens follow your device setting, so late-night ticketing is easy on your eyes.

■ What it doesn't do
No auto-clicking or macros. It's a server clock that only shows the time. No login, no sign-up and no booking screen inside the app.
