Precision Millisecond Timer

Precision Millisecond Timer is a display-grade millisecond stopwatch built for engineers measuring end-to-end latency of wireless video links (FPV, drones, industrial video transmission). Key features: · Max refresh rate lock — runs at your device's highest refresh rate; display granularity down to ~8.3ms (60Hz) / 4.2ms (120Hz) · Midpoint prediction — predicted readings based on measured fps reduce photo-read error from −16.7ms to ±8.3ms on 60Hz devices · Fullscreen shoot mode — pure black background, huge digits, live fps badge; designed to be captured by another camera in a single shot · Latency log — enter TX/RX readings, auto-compute the delta, and keep history to compare links, bitrates and antennas · Multi-language, adaptive dark mode All measurement data stays on your device. We collect nothing.
