About this app

SyncTrack is a timing and starting tool designed for track and field training and small competitions. One mobile phone can start, time, and record; two phones can be placed at the start and finish lines respectively to synchronize and complete a full timing cycle.

■ Standalone Starter

・Built-in multiple starting sounds, supporting three starting sequences: "On your marks—Ready—Gun," "On your marks—Gun," and "Ready—Gun."

・Starting intervals can be fixed or randomized within a range, more closely resembling the rhythm of a real race.

・Timing starts at the sound of the gun, displayed in large font for easy visibility from a distance.

・Supports manual starting mode, allowing coaches to control the pace.

■ Starting and Recording

・One phone simultaneously starts and records, using the gunshot detected in the recorded audio track as the timing zero point.

・If no gunshot is detected, the zero point can be manually set during playback.

■ Video Timing and Frame-by-Frame Playback

・Import any running video clip, set the starting frame, and the time will be displayed.

・Location is based on the actual time of each frame, with millisecond-level readings, not estimated based on the nominal frame rate.

・Finish line measurement aids in accurately determining the frame in which the torso crosses the finish line.

・Automatically detects dropped frames in the recording and displays the actual frame rate.

・Supports exporting playback videos.

■ Networked Race (Two Devices)

・One device acts as the starting point for issuing the starting signal, and the other as the finish line for displaying the finish line and timing.

・Supports direct LAN connection and remote networking; the two phones do not need to be connected to the same network.

・Automatic time synchronization between devices; the finish line operates silently throughout, without disturbing the event.

・Both the starting and finish lines can have the right to issue the starting signal, switching as needed.

・Optional "Ready?": The starting signal can only be issued after the other device confirms readiness.

■ Starting Reaction Time Test

・Uses the phone's motion sensor to detect the starting moment, measuring the reaction time from the gunshot to the start.

・Supports false start detection; sensitivity is adjustable.

・Suitable for daily starting reaction time practice.

■ Theoretical Performance Calculator

・Input measured performance, wind speed, and altitude (temperature, air pressure, and humidity can also be selected) to convert to a theoretical performance (100m) under 0 wind and sea level conditions.

・Parameters can be saved as presets for convenient reuse.

■ Other features:
• Centralized management of every starting signal, timing, and recording.
• Camera delay calibration improves finish line timing accuracy.
• Automatic screen dimming when not in use saves power for outdoor use.

Suitable scenarios: School physical education classes and physical fitness tests, daily training for track and field teams, individual sprint practice, and small-scale test events.

Timing results are affected by equipment performance, camera frame rate, and usage; they are for training reference only and should not be used as the basis for official competition results.
