陸上 スタート音 -STARTER PISTOL-

Practice your track and field starts seriously with just your smartphone.

"STARTER PISTOL" is a training app for start practice that combines everything from playing realistic start signals to measuring reaction time and speed, and recording and comparing your form. It can be used for practicing in track and field, including sprints, and any sport where reaction time at the start is crucial.

■ Realistic Start Signals
The app automatically plays the "On Your Marks → Set → Go" phases in order. You can finely adjust the waiting time and sound for each phase, faithfully reproducing the actual command flow.

■ Random Timing for False Start Prevention
The interval from "Set" to the gun can be set to a fixed time or randomly within a specified range. Since the timing changes each time, you can correct guesswork and false starts, developing strong concentration for actual races.

■ Reaction Time Measurement and False Start Detection
The app measures the time it takes to react to the gun and displays the result numerically. If you move before the starting gun, it will be detected as a false start, and the exact speed will be recorded. The measurement items (reaction, speed, goal) can be freely combined.

■ Customizable Voice and Intervals
Adjust the voice and timing of each phase to your liking. Loop playback is supported, facilitating repeated practice.

■ Record Start Form on Video (Camera Mode)
Record the start moment in real time and review your form and start sprint later. The video's seek bar displays a marker at the moment the signal sounds, allowing you to check "where the difference occurred" frame by frame. Video naming, favorites, and sharing are also supported.

■ Compare Form with Two Videos Side-by-Side
Select two videos from your recordings and place them vertically, automatically aligning and synchronizing playback at the timing of the starting gun. Compare your movements with your past self or teammates. Horizontal flipping is supported, and you can export the comparison video as a single video file for sharing.

■ GPS Speed ​​Measurement and Comparison (Measurement Mode)
Measure your running speed using GPS and visualize it with maximum speed, graphs, and 10m splits. You can overlay and compare graphs from multiple records, allowing you to see daily speed changes at a glance.

■ Realistic Time Measurement with Two Smartphones
Place one smartphone at the start and one at the finish line to measure start and finish times. Easy connection with a 6-digit code. The runner's maximum GPS speed is also recorded, and false starts are immediately notified to both devices. Even when running alone, setting the finish-side device to "record" allows you to determine your finish using frame-by-frame video playback.

■ Automatic Recording of Measurement Logs
Measured time, reaction time, and speed are automatically recorded. Organize your past training sessions with titles, notes, tags, and favorites, and track your progress anytime.
