Stop watching the clock โ€” we'll remind you! VoiceTimer is a smart countdown app that shows and announces how much time remains until your target. Perfect for cooking, studying, or any task where you can't keep your eyes on the screen. It reads the remaining time aloud and notifies you exactly when you choose. * A successor to "Countdown Calendar," released over 10 years ago. Key Features - At-a-Glance Countdown: Remaining time is displayed in large, easy-to-read digits. Even with multiple targets registered, the nearest one is always shown front and center. - Tap the Speaker to Hear It: Tap the speaker button to hear the current remaining time read aloud โ€” ideal when your hands are full. Choose your language (Japanese/English) and voice (female/male). - Flexible Pre-Alerts: Combine multiple reminders from 14 timing options, from 5 seconds to 1 hour before. You'll get a voice-enabled notification even when the app is closed. You can also enable a final countdown that speaks "10, 9, 8โ€ฆ" for the last 10 seconds. - One-Touch Kitchen Timer: Save your most-used durations to a button for instant setup. Give them custom names, and your most-used buttons are automatically highlighted. - Repeating Timers: Daily, weekdays, weekly, or monthly โ€” automatically restarts the countdown after each completion. - Calendar & Reminders Integration: Pick any event and start counting down to it instantly. - Always Visible on Lock Screen & Home Screen: Full Live Activities & Dynamic Island support! Check your next event at a glance with a Home Screen widget, or start a kitchen timer with one tap right from your Home Screen. - Make It Yours: Customize with 55 color themes (across 7 categories), theme-matched ambient animations (adjustable in 3 levels), and 5 alarm sounds.

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 ยฑ500ms 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: ยฑ23ms. 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, ํ•œ๊ตญ์–ด, ๆ—ฅๆœฌ่ชž
