Make every 00-second moment easier to catch. CUE! is a time signal app designed for timer setup and field time checks. With NTP-based time correction, 57/58/59/00-second countdowns, signal sounds, haptics, and voice announcements, CUE! helps you catch the exact 00-second moment. It is useful for temporary illumination timer panels, facility equipment, electrical work, lighting and audio systems, events, exhibitions, filming, streaming, stage work, live shows, store displays, and any situation where second-level timing matters. ■ CUE!’s Time Correction Logic CUE! is not a clock that simply displays the result of a single NTP request. NTP responses can vary depending on network routes, congestion, Wi-Fi, mobile networks, and device conditions. CUE! collects multiple NTP samples during startup and manual sync, checking each sample’s round-trip time (RTT) and time offset. Slow responses and offset outliers are filtered out. CUE! prioritizes stable samples. The selected NTP time is linked to the device’s monotonic clock at the moment it is received. After that, the in-app time display advances by adding elapsed monotonic time to the NTP reference. During automatic sync, CUE! may keep the previous NTP reference instead of applying a low-confidence result. This helps prevent sudden jumps caused by unstable network responses. ■ 57/58/59/00-Second Cues CUE! starts its countdown at 57 seconds every minute. 57 sec: 3 seconds before 58 sec: 2 seconds before 59 sec: 1 second before 00 sec: CUE! At 00 seconds, the time and cue display change color, making the exact moment easy to recognize visually. It helps when setting timer panels, checking lighting and audio timing, starting streams or recordings, managing events, and confirming 00-second timing in the field. ■ Sound, Haptics, and Voice CUE! can notify you at 57/58/59/00 seconds with signal sounds and haptics. Signal sound can be turned on or off. Use sound when allowed, or turn it off and rely on the display and haptics. Haptics use different patterns for warning seconds and the exact 00-second cue. Haptics can also be turned on or off. Voice announcements help you understand timing even when your iPhone is in your pocket. Choose announcements every 1 minute, 15 minutes, 30 minutes, or 1 hour. CUE! supports English, Japanese, Simplified Chinese, Traditional Chinese, and Korean. Other languages fall back to English. ■ Landscape Display Turn your iPhone sideways to use a larger clock display. This is useful when placing your iPhone on a stand, near a lighting console, audio mixer, or timer panel. ■ Field Features CUE! includes: ・Display dimmer ・Keep-awake mode ・Rear flashlight control ・Cue color toggle ・Haptics ON/OFF ・Signal sound ON/OFF ・Portrait and landscape layouts ・Remove ads option ■ Recommended For ・Temporary illumination timer setup ・Facility equipment time setting ・Electrical work and field timing ・Lighting and audio timing checks ・Events, exhibitions, stages, and live shows ・Streaming, recording, and filming start cues ・Store display and timer control checks ・Checking every 00-second moment clearly ・Using a clock that always shows seconds ・NTP-based time checking CUE! is a field time signal app that supports the exact “now.” ■ Free to Use CUE! is free to download. Banner ads are shown in the app. To avoid interrupting important timing moments, CUE! does not use interstitial ads. You can remove banner ads with an in-app purchase. ■ Notes CUE! uses public NTP servers to support its in-app time display. However, differences may occur due to network conditions, device status, screen rendering, audio output, haptics, speaker latency, or Bluetooth device latency. CUE! does not guarantee millisecond-level synchronization, measurement accuracy, broadcast timing, or legal proof of time. However, it can be a useful support tool for timer setup, 00-second alignment, and second-level time checks in field environments.
MinSec Clock

See hours, minutes, and seconds clearly in the app, on the Lock Screen, and in the Dynamic Island. On supported devices, use Picture in Picture to keep the clock visible over other apps. MinSec combines a precise seconds display, a full-screen desk clock, and customizable clock faces in one clean iPhone app. WHY MINSEC - Dynamic Island and Lock Screen time: show your selected hours, minutes, seconds, and optional fractional seconds with a Live Activity - Picture in Picture clock: keep the clock visible over other apps on supported devices - Lock Screen clock: check the current time without unlocking - Full-screen desk clock: turn your iPhone sideways for a clear landscape display - Analog and digital clock faces: switch styles to suit the moment - Custom time display: choose which hours, minutes, and seconds to show, plus fractional seconds - Detailed time: choose 12- or 24-hour time and display fractional seconds - Personalize the look: use a smooth second hand and a choice of accent colors - Shortcuts support: quickly start or stop the Live Activity - Private by design: no ads, accounts, analytics, or tracking MinSec uses your iPhone's system time and does not require a network connection. Seconds on the Lock Screen and in the Dynamic Island use Live Activities. iOS allows each Live Activity to run for up to 8 hours. On some older iOS versions, it may stop at midnight; restart it to keep displaying the time.
