## What is 拆招 FormLoop?

Learning a martial arts form from video is hard when the moves fly by — a turn, a palm strike, gone before you see it. FormLoop is built for exactly that: slow it down, loop the part you need, and watch it until you have it.

[Loop a section]
Mark a start and an end point on the timeline, and FormLoop repeats just that part. Practise one move until it's yours. Save as many named sections per video as you like and jump straight back to any move next time.

[Slow motion]
Slow the video down to see every shift of hands, feet and weight.

[Smooth slow motion] (FormLoop Pro)
Ordinary slow playback stutters frame by frame. FormLoop fills in the in-between frames, so movements stay fluid and you can see how one move flows into the next. (On supported devices; otherwise the app plays regular slow motion.)

[Your own videos]
Import .mp4 and .mov files from Files or Photos — your teacher's demonstrations, class recordings, or your own practice footage.

[Free and FormLoop Pro]
The free version includes section looping and 0.75x slow motion, with up to 3 videos of up to 1 minute each.
FormLoop Pro is a one-time purchase, yours to keep (no subscription):
‧ Smooth slow motion with in-between frames
‧ Slower speeds: 0.5x, 0.25x and 0.1x
‧ Unlimited videos of any length

[Who it's for]
‧ Practitioners of Tai Chi, Baguazhang, Xingyiquan, Changquan, Nanquan and other forms
‧ Anyone learning from video who needs to break a form down move by move
‧ Anyone who wants to slow down their own practice footage and compare it with their teacher's

[Privacy & Security]
‧ Videos are processed on your device and never uploaded
‧ No account, no ads, no tracking
‧ Independently built by Intoxicated Child Studio
