Ticket sales and class registration open on the site's server clock, not on your phone's clock. Nanotime reads what time that server says it is and shows it down to 1/100 of a second. ■ See how accurate it is The remaining margin is shown as ±ms next to the clock. If the reading gets old or the server's clock wobbles, you'll know right away. ■ A clock that floats over the booking page Keep the booking page open and watch the server clock in a small floating window (PiP). It keeps running after you leave the app. ■ Sound and vibration at the exact second A signal every second from 10 seconds out, with a different rhythm for the last 3 seconds. No need to watch the screen. ■ Alerts before it opens Save the opening time and get alerts at the times you choose for each one. ■ Rehearsal Practice a drop 10 seconds ahead on the real server clock. It's scored by when your click reaches the server, not when you tapped. Use it for concert and show tickets, sports tickets, class registration, limited releases and first-come sign-ups. If a site isn't listed, just enter its address. No auto-clicking and no macros. It only shows the time.
