More answers

Can I use INFORM offline?

You can review and analyse local videos offline, including motion tracking once any required model has been downloaded. YouTube playback and optional online features need an internet connection.

Can I use videos I already have?

Yes. Open a video from your phone, record directly in the app or paste a YouTube link. On Android, you can also share a link from the YouTube app.

Does INFORM tell me how to improve my technique?

INFORM gives you tools to observe and measure movement. You or your coach interpret what you see and decide what to work on next.

Why was INFORM built?

As a dancer, weight lifter, rock climber and dance coach, I wanted a video analysis tool that fitted the way I trained and coached. I built INFORM to bring the tools I needed into one place.

Common questions

How do I send a clip to my coach or my client?

Open the video, set the loop markers around the part that matters, then tap Share in the top bar. INFORM cuts that section, and the Burn into video option writes your drawings permanently into the picture so they appear in the exported clip. Your typed notes travel as the message text and any voice notes go along as files. It is then handed to your phone's normal share sheet — messages, email, anywhere you already send video. Nothing is uploaded by INFORM itself.

If the person on the other end also has INFORM, share it as an INFORM file instead: it re-opens on their phone with every drawing still editable, so they can answer you on the same frames.

Do I have to save my drawings?

No. INFORM automatically saves drawings, measurements and notes on your device in a file beside the video.

Why can’t I see my drawings when I reopen a video?

That is deliberate: a video opens with a clean picture every time, so you are never drawing on top of last week's marks. To keep a marked-up version, save it while the drawings are on screen — Save in the top bar, or file it into a project — and choose Burn into video. That writes a new video with the drawings permanently in the picture.

How do I compare two videos side by side?

Tap Compare on the opening screen, or the compare button in the top bar, and open a video into each half. Tap a video to select it — the blue outline shows which one the buttons will act on — and use the selection button in the shared bar at the bottom to switch between driving both videos and driving only the selected one. Rewind always drives both.

Two takes of different lengths still loop together: the shorter one waits for the longer to come round. Tapping the grey mark on the cue lane matches their lengths for you, and a drift corrector keeps them lined up once they are running.

How do I track a barbell, a hand or a whole body?

Choose the tracking tool, then tap the thing you want to follow — a plate, a hand, a foot — or drag a line along it, and tap Track. INFORM follows it through the clip and draws its path behind it, and the angles you have drawn on it update as it moves. Tracking runs on your phone; nothing is uploaded.

Body tracking, which follows a whole skeleton, needs a pose-detection model that is too large to ship inside the app. The first time you use it INFORM asks before downloading that file, about 9 MB, and afterwards it works offline. The privacy policy says exactly what that download involves.

How do I measure an angle?

Choose the angle tool from the tool menu and place three points — end, corner, end — by tapping, or by drawing the two lines. Anything you draw near square is pulled onto 90°. With the shape selected you can log it, which appends a line like 132° @ 0:04.3 to that clip's notes, so a session leaves a list of measurements behind.

How do I record feedback for a client?

Tap the record button in the top bar. The sheet asks one question — what should happen to the clip's own sound while you talk: Mute clip, Auto-mute (it drops while your microphone is on) or Talk over. On iPhone the clip is muted while you record, so that question does not appear.

The take begins paused: press play in the recording controls when you are ready, and press it again to pause. The microphone starts shut — tap it to open, and it turns blue for as long as your voice is going into the file. Coach view puts your camera in a bubble you can drag and pinch. Stop opens an edit screen where you trim the ends with the loop brackets, crop the picture, and then save or share it.

How do I open a YouTube video?

Use YouTube on the opening screen and paste a link. On Android you can also use the Share button inside the YouTube app and pick INFORM. YouTube clips play through YouTube's own player inside INFORM, so they can be slowed, looped, drawn on and compared against your own footage — but they cannot be saved or exported, within INFORM.

How do I free up storage?

Video is large, and INFORM keeps its own copy of anything you open so your drawings have something stable to attach to. Free Space on the opening screen shows how much is held and clears it by age or by kind, and Auto-clean, inside that same screen, sets a standing rule — delete raw videos older than a month, say. Auto-clean is off unless you turn it on, and both tell you exactly what will go before anything goes.

How do I get my work off the device?

A single clip or photo goes out through the share sheet. A whole project goes out from the projects hub with ⋮ → Back up, which zips the folder — videos, images, drawings and notes together — to wherever you want to put it. Unzipping that folder back into the projects folder restores it.

Can my gym, studio or club use INFORM?

Yes. Coaches and teams can use the standard INFORM app. If you run a training platform, contact us about customised integration.

If something goes wrong

If available, attach INFORM’s errors.log file when reporting a problem. It contains error messages that can help us investigate.

Along with the log, say which INFORM version you have (printed at the foot of the opening screen), which phone, and what you were doing when it went wrong. Use the “Report an issue” email link above to include these details.

Requirements

A camera and a microphone are optional — INFORM works on video you already have without either.

Privacy

No account is needed right now. We plan to introduce accounts and sign-in as INFORM develops.

Your videos, drawings and notes are currently stored on your device. Cloud storage and sharing are on our roadmap. We’ll explain how your information is handled before these features launch.
