TrueOffset

Precision NTP Clock

Free · Designed for iPad

Measure time with confidence. Compare NTP servers, verify device offset, and view a precision clock designed for accuracy. 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 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. 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. STATISTICS & HISTORY View average offset, jitter, and per-server measurements. A 30-minute history chart tracks drift over 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. --- NTP synchronization powered by Kronos.
