Built for dancers, lifters, climbers, boxers and any sport where technique matters, and for the coaches and teachers who want the most for their students. Slow motion, frame-by-frame, motion tracking, angle measurement and side-by-side comparison, all on your phone.
See it in action
Short, practical walkthroughs of the tools that help you find and explain what happened in a movement. More arrive on Instagram at @InFormMotion.
What it does
Film directly in InForm, open a video already on your phone, or paste a YouTube link. On Android, you can also share straight from the YouTube app. Then take the movement apart, one frame at a time.
Step one frame at a time with the arrows, or hold them to walk through the moment. Hold a speed anywhere from 0.25× to 2×. Set two markers and loop the same two seconds twenty times while it sinks in.
Drag your finger away from the scrub bar and it gears down, to half speed, a fifth, a twentieth, so you can land on the exact frame with a thumb. Pinch to zoom into the part that matters, and mirror the view to see a move the way you would face it.
Advanced motion tracking of points, lines, angles and body parts. Tap a hand, a barbell plate or a whole skeleton and InForm follows it across the clip, drawing the path behind it and reading live angles at the joints.
A bar path that drifts forward, a knee that caves, an arm that drops before the punch lands: see your movement to perfect your movement.
Put two videos next to each other and play them together. A YouTube clip beside your own attempt, to learn a sequence. Today beside six weeks ago, to see whether the training is working. Sync them, loop them and step them both forward a frame at a time. A drift corrector keeps them lined up when the two takes aren’t the same length.
It is a form check you can actually see. Students who swear nothing has changed go quiet when today is sitting next to March.
Pen, line, arrow, ellipse, text and a real angle tool that snaps to square and stays accurate whatever shape the video is. Every drawing has its own visibility window, so a note appears only over the moment it’s about.
Type a note, or record your voice against an exact moment. The recording sits inside the sentence you wrote. Tap it to hear it and jump the video there.
Why I built it
As a dancer, weight lifter, rock climber and dance teacher, I was always looking for ways to study movement. I wanted a simple but powerful video analysis tool that worked the way I actually trained and taught, and I could never find the right one. So I built InForm.
And
All of it is in the same app, and what is still coming will arrive the same way. There is no second tier.
Capture the screen while you talk over the video and draw on it, then trim it, crop it, and send the whole review as one clip.
Film directly in the app, or open a video already on your phone. Nothing to import, and nothing to set up first.
Save clips and stills into dated project folders with a pose tag, so months of work read left to right in a single view.
Flip the picture to see a move the way you would face it, drawings and measurements flipping with it. Nothing in the file changes.
Paste a link, or share straight from the YouTube app, and study the performance you are trying to learn from.
Cut out the part that matters and send it with your drawings burned into the picture, or as a file that re-opens with every mark still editable.
Your videos
InForm has no server. There is no account, nothing is uploaded and no analytics are collected. Everything runs on your phone, the motion tracking included. That matters if you teach, and it matters more if you teach children.
Being straight with you
Worth knowing before you install it rather than after.
For individuals
I believe quality resources should be available to everyone who loves motion, whatever their budget. For individual users InForm is donation-ware: every feature, as much as you want, with no subscription, no ads and nothing hidden behind a paywall. I trust that enough people will find InForm helpful to support its continued development.
If InForm is of value to you, please donate through the Support screen in the app. A rating, a positive review and a word to friends and teammates help just as much.
For gyms, studios, clubs and teams
Run a gym, a dance studio, a climbing wall, a boxing club or a coaching practice? InForm can be integrated into how your business coaches and teaches, with licensing and support to match. Reach out and tell me what you need.
Talk about your businessFilm a move or open a clip you already have. Find the frame that explains what happened, and take that insight into your next attempt.
