Mark the part you want to practice
Import from Photos or Files, then mark the few seconds you want to repeat.

ReplayFlow
Practice with a reference video, record yourself, then compare the two side by side.
Import the reference clip you want to practice, slow it down, loop it, or mirror it to see the details. Then record yourself and review it next to the reference.
Practice should not mean switching tools all the time.
A clip moves too fast, the part you need is short, and after recording you have to find the reference again. Those little interruptions make practice feel fragmented.
- Want to repeat a few seconds but keep missing the right place?
- Forget the move as soon as you switch from the video to the camera?
- Have to find the reference video again after you record?
ReplayFlow puts those steps into one repeatable practice flow.
Three steps. One complete practice.
Choose a clip, record in sync, then review side by side.
Record while watching the reference
Keep the reference on screen, follow along, and record your own version at the same time.
Review side by side right away
When recording ends, go straight to a synced comparison of timing, direction, and positioning.
While practicing
Keep the reference in view while you record.
The reference and camera are visible together. Follow the move while you practice and record—without jumping between apps.
- Use picture-in-picture, stacked, or side-by-side views.
- Set a countdown, choose a camera, zoom, and focus before recording.
After recording
Set up the comparison so differences are easiest to see.
Play in sync to check timing, then slow down, step through frames, or adjust the layout to see differences in movement, direction, and position.
- Switch between stacked, side-by-side, and picture-in-picture views to find the clearest comparison.
- Adjust aspect ratio, position, rotation, and scale; export the comparison when you need it.
Make the hardest few seconds easier to follow.
Use slow motion, loops, frame stepping, and mirroring to break down details. Crop the frame and organize regular clips so you can pick up where you left off; export when you need to.
Loop a segment
Mark the segment you want to repeat and keep playback within that range.
Slow motion
Slow the reference down to see timing, balance, and direction more clearly.
Frame stepping
Pause and move one frame at a time to check position and timing.
Mirror practice
Flip the reference video horizontally so you can practice in the same direction more easily.
Crop the frame
Crop away what you do not need for a more focused practice view.
Save and organize
Name, categorize, and save the clips you practice often so you can pick up faster next time.
Build your practice library
Open it next time and continue with the settings you know.
Saved clips keep their A/B range, speed, mirror, and mute settings. Name and categorize videos and clips so regular practice is easy to find again.
