Side-by-side video analysis for iPhone coaching
Feedback that stays in your athlete's pocket
Draw the correction on the frame, slow it to 1/8x, compare side by side — the annotated review syncs to your athlete's library and is there before every practice.
In a 2022 meta-analysis of feedback in physical education, spoken corrections alone showed no significant effect — visual plus verbal was the strongest. The research

Give feedback that stays with them
Invite a student with a QR code, link, or email. They join on the free app and work from your shared cloud storage — up to 500 GB on the Coach plan. Every attempt lands in their workspace, and your annotated review syncs back and is waiting in their library the next time they open the app.

Show the difference side by side
Stack an attempt against a reference, set one shared sync point, and both timelines move together — frame steps stay aligned even when one clip is 30 fps and the other is 60. Slow the pair to 1/8x and the difference stops being a feeling and becomes a frame you can point at.

Tools built for coaching video
Two videos, one shared timeline
- Attempt and reference on one screen, played in sync
- One sync point keeps both timelines aligned around the same moment
- Mixed frame rates step together — 30 fps against 60 fps stays true
- Pinch to zoom and pan each video independently
Scrub one true frame at a time
- Step forward or backward a single frame from the controls
- The frame step is derived from both clips' frame rates, so neither drifts
- Precise seeks land exactly on the frame you chose
- A fine scrubber wheel for the half-second that matters
Slow it down until it is coachable
- Playback at 1x, 1/2x, 1/4x, and 1/8x
- 1/8x turns a blurred half-second into a sequence you can talk through
- Slow motion works in synced side-by-side playback too
- Combine with frame steps to freeze the exact position
Draw the correction on the frame
- Seven tools: freehand, freehand arrow, straight arrows, lines, circles, angles, and rectangles
- Draw during 1/8x playback so the line follows the moving joint
- Auto-fading marks clear themselves — no cleanup between attempts
- Annotations stay on the frame they describe
Keep only the attempt that matters
- Trim long recordings down to the movement
- Extract multiple clips from one continuous video
- Share footage straight into WithCoach from other apps
- Paste a web link to bring in a reference video (Beta)
Send the review, not a screen recording
- Exports match the review — drawings and timing intact; single-video exports keep the source audio
- Save to Photos or Files, or share a review link on Pro and up
- Free exports carry a WithCoach watermark; paid plans remove it
- Reviews sync back to your student's library
A workspace for every student
- Invite students with a QR code, link, or email
- Each student's attempts, references, and reviews stay organized
- Students join on the free app and share your cloud storage — up to 500 GB on Coach
- An activity feed keeps the whole roster in one place
