Nanotime vs Atto

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.

A ticket drop is decided in milliseconds, not seconds. The queue opens on the booking server's clock, not your phone's. The two are usually tens to hundreds of milliseconds apart, and that gap decides your place in line. Atto reads the server's clock directly, and shows you how well it read it. Measuring server time An HTTP Date header only resolves to the second, so one read tells you ±500ms and no more. Atto probes at 137ms intervals so each request lands on a different phase inside the second. Once the offset narrows, it predicts when the server's second will roll over and aims at that edge. Twenty overlapping measurements fold the error down to the round trip. The error bar stays visible Instead of a label like "high accuracy" you get the measured figure: ±23ms. Sample count, rejected samples, best round trip, and how far this server runs from national standard time are all on screen. Cached responses get dropped When a CDN answers instead of the origin, the clock inside that response is frozen at the moment it was stored. Atto checks the Age and cache headers and keeps those responses out of the average. Device drift correction Your phone's oscillator runs seconds off per day. Atto measures the slope between syncs, extrapolates it to now, and re-syncs every two minutes while you wait. Picture in Picture Press Start and a Picture in Picture window floats above your other apps. Show a decreasing countdown or a corrected wall clock that advances toward your configured target, with three-digit milliseconds. Keep the timing in sight while using a booking app or webpage. Haptics and sound Taps begin at the lead time you set and end with one hard hit at zero. The whole pattern goes to Core Haptics up front rather than a timer, so zero does not move even if the screen stutters. Sound is optional and plays through the silent switch. Practice mode A recommended lead time is somebody else's number. Measure the gap between the buzz and your tap actually registering, then apply your own median. Time sources Over 300 sources across 14 regions, including Ticketmaster, AXS, StubHub, Interpark, e+, tixCraft and Damai, plus course registration sites and sneaker drops. Standard-time servers like NIST, NPL, PTB, NICT and KRISS are there too, and you can type any address yourself. Free and paid Everything that decides whether you get the ticket is free: full sync accuracy, drift correction, the on-screen countdown, haptics, every time source, practice mode. One rewarded ad floats a single countdown in a PiP window. A one-time purchase removes ads and keeps PiP unlocked. It is not a subscription. Reading a clock takes one HEAD request. Atto never asks for an account and takes no part in the booking itself. English, 한국어, 日本語
