0.1s (PointOne): Server Time

Course registration, concert tickets, limited drops — when a booking opens, 0.1 seconds can make the difference. But your phone's clock and the site's server clock rarely agree. Point One shows you the time the site's server is keeping, down to the millisecond, so you know when to press. ⏱️ Server time, always with its ±error Pick a site or type any address. Point One measures the server's clock several times and corrects for network delay. The result always comes with its ±error and how long ago you synced — it's an estimate, and we show you how good it is. If the error grows, the app tells you to sync again. • Fast, Standard (recommended), Precise or Custom accuracy • "Press about N s early" — an estimate of how long your tap takes to reach the server 🔔 Countdown to the opening time Set the opening time and the clock counts down in milliseconds on server time. The screen turns amber from 15 s before and red on the mark, with short beeps at 3·2·1 and a vibration on the mark. Three minutes before opening, it re-syncs automatically. 🪟 Float as pop-up (PiP) Keep a small server-time window on top of the booking or registration page in your browser. Pick the window shape that covers the least, and let it close itself at a time you choose so it never gets in the way of seat selection or payment. (Android 8.0 or later) 🖥️ Full-screen clock A big landscape clock for when you just want the time on screen. 📅 Schedules Save the openings you can't miss. When the notification arrives, tap it and Point One opens and syncs right away. 🌐 Sites Browse the built-in lists (Time servers, Universities, Ticketing, Others), search them and keep your own Favorites. The built-in list is mostly Korean sites, plus standard time servers and some international sites — but you can type in any site address and sync to it. 🎯 Practice • Reaction time — press right on the mark and see how many ms early or late you were • Ticketing simulation — opening → Book → queue → CAPTCHA → seat selection • Course registration simulation — Watchlist → Apply → CAPTCHA → Confirm For practice only. Real results are not guaranteed — real sites' queues, CAPTCHAs and seats differ from site to site. 🎨 Timer themes Choose a preset or set your own background, digit, accent and mark colors and a monospaced digit font. Light, dark or system appearance. 💡 Ads and Point One Pro No banner ads, no interstitials, no ads when you open the app. The only ads are optional rewarded ads you choose to watch — for example to start the pop-up or to unlock a feature. From 3 minutes before your opening time, no ads are shown and the pop-up starts right away. Point One Pro is a one-time purchase, not a subscription: no ads, Precise & custom accuracy, all timer themes, ticketing & registration practice, and unlimited & repeating schedules. 🔒 Privacy No account, no sign-in. Your settings, favorites, schedules and records stay on your device. Point One helps you see the time clearly. It can't promise you a seat or a class — that also depends on the site, your network and everyone else pressing at the same moment.
