Let's record children's practice easily and safely with this app. What you can do with this app -Recording- · Play sound (start signal) · Start recording video · Start timer · The above three can be started with one tap!! · You can play your favorite sound from 10+ sounds. · Date and lap time can be displayed on movies. -Play video- · Play video with timer · Start checker: Player for finely checking the motion before and after the start · Double screen: Player for comparing two video simultaneously *Each player are played on the basis of "start point" (It’s mean when race was start in the video).
