Prime Time NTP vs Tick Sync

"Prime Time" is a high-precision time app that shows the true time, accurate to the millisecond. It queries NTP servers directly — the same infrastructure that keeps the internet in sync — and works out the correct time from their answers. Your device's own clock is never used for the display. [New in version 1.4] • Display Offset (Pro): run the large clock up to 99.999 seconds ahead of or behind real time, in 1 ms steps — for remote broadcasts, live streams, or any delayed feed. While it is on, the time turns yellow, with the offset above and the actual time below, so there is no mistaking it for real time. Measurements are never shifted. • Server details now use two columns in landscape on iPhone, so everything fits on one screen. • On iPhone with ProMotion, the clock now refreshes up to 120 times a second. [Free — one server, in full detail] • Real-time sync with one NTP server of your choice • Every exchange laid open: address, stratum, reference, root delay, jitter, estimated error, and the last eight exchanges • Millisecond display, refreshed up to 120 times a second on ProMotion screens • Offset and round-trip time with sparkline history • Adaptive polling that eases off as a server proves steady [Pro — one-time purchase, no subscription] • Compare up to 30 servers. With three or more, a server that is off is outvoted instead of skewing the time shown. • Manual sync on demand • Keep the screen awake while the app is open • Display Offset: run the clock ahead of or behind real time A note on accuracy: a round trip is a single number covering two unknown halves, and nothing in the exchange reveals how it was divided. Prime Time widens the reported ± rather than inventing a correction to hide it. On cellular, where the two directions are least alike, that margin is wider — and shown. Made for developers, network engineers, broadcast crews, and anyone curious about how far off their device's clock really is. Available in English, Japanese, German, and French.

When standard time radio signals do not reach your area, or walls and interference prevent your watch from receiving them—Tick Sync provides another path to the correct time. Start with radio-controlled watch assistance. Place the watch near the built-in speaker of your iPhone or iPad and begin manual reception. Tick Sync generates time codes for JJY 40/60, WWVB, MSF, DCF77, and BPC, helping the watch attempt synchronization over a very short distance. For explicitly compatible Bluetooth watches, pair and connect the watch, wait until it is ready to sync, and then send the current local time manually. With Advanced Features, Tick Sync can maintain an eligible Bluetooth connection in the background. When the watch reconnects and becomes ready, Tick Sync normally obtains a fresh NTP correction and sends the time automatically, reducing the need to open the app for every sync. Background timing is determined by iOS or iPadOS and watch connection events rather than an exact schedule. Your time source is not limited to the device’s system clock. Free Single NTP mode queries a server you choose. Multi-NTP mode compares at least three independent sources, finds a majority-agreed time range, rejects inconsistent responses, and displays estimated uncertainty. HIGHLIGHTS • Very-short-range JJY 40/60, WWVB, MSF, DCF77, and BPC radio-controlled watch assistance • Manual and background automatic Bluetooth time sync for explicitly compatible watches • System Time, Single NTP, and Multi-NTP sources • NTP server management, optional location preselection, outlier rejection, and uncertainty estimates • Watch battery level display • No account required Radio assistance, manual Bluetooth time sync, System Time, and Single NTP are free. Background automatic Bluetooth sync and Multi-NTP features require an auto-renewing annual Advanced Features subscription. Tick Sync is an independent utility and is not affiliated with any watch manufacturer. Bluetooth compatibility depends on the watch model and firmware, while background operation depends on iOS or iPadOS and watch connection events. A successful Bluetooth write does not guarantee that the watch applied or displayed the new time. An iPhone or iPad does not transmit a normal 40–77.5 kHz longwave broadcast. Radio-assisted results vary with the device, watch hardware, volume, placement, and interference. Always verify the final time independently before relying on it.
