TrueOffset vs Tick Sync

TrueOffset is a precision time utility for comparing time sources and measuring clock offset with clarity and confidence. Compare multiple Network Time Protocol (NTP) servers, visualize the difference between them, and see how your device's clock aligns with selected references. A clean, instrument-style interface presents time as a measurement—focused on accuracy, not decoration. FOUR CLOCK FACES - 12-Hour Classic — Traditional analog display - 24-Hour Scientific — Full day on one dial - NTP Offset — Dual second hands show device vs. true time - Digital — Large display with millisecond precision UTC & TAI TIME SCALES Display Coordinated Universal Time (UTC) and International Atomic Time (TAI) alongside your local time. UTC and TAI feature authentic deadbeat second hands that step crisply to each second, visually distinct from the smooth-sweep local time. TAI runs 37 leap seconds ahead of UTC—see both atomic time scales at a glance. PRECISION VISUALIZATION The NTP Offset view displays two second hands: your device clock (gray) and true NTP time (green). The offset magnifier shows drift on a ±10ms scale, so you can see sub-millisecond accuracy at a glance. DUAL-STACK COMPARISON A feature no other NTP app offers: compare IPv4 and IPv6 paths to the same server. Detect DNS misconfigurations, identify when address families route to different servers, and verify your network is delivering consistent time on both stacks. FLEXIBLE TIME SOURCES Compare against Apple, Google, Cloudflare, NIST, US Naval Observatory, global NTP pools, or add your own servers. Set any source as your reference and track offsets across all configured servers. QUALITY ANALYTICS Eight swipeable chart pages reveal the character of your time sources: - Dashboard — Sparkline overview of all servers - Offset History — Track drift over time - Histogram — Offset distribution analysis - Box Plot — Compare consistency across servers - RTT Scatter — Correlate latency with offset - Clock Sources — Decode reference clocks (GPS, PPS, Rubidium, Cesium) - Dual-Stack — IPv4 vs IPv6 path comparison - Rankings — Servers scored by jitter and round-trip time TrueOffset is designed for users who care about how accurate their time really is—and want to see the difference, not just trust it. --- In appreciation of Emerald Sequoia's Emerald Time.

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.
