Camera

Test footage: Conanta & Virginia, MyDeadlift, CC BY 4.0 (unmodified GB_S01_R01.mp4). Not an endorsement or a model of ideal technique. Your own footage is never uploaded.

Camera permission is requested only when you tap. No audio, account, or cloud processing.

02 / SETUP

Place your phone still, directly side-on. Keep the whole plate visible.
With the bar on the floor, tap the plate’s center in the video.
Match the plate size, then tap the hub again to lock. Analyze or record your set.

Plate size in frame 100 px

Match the ring to the plate’s outer edge. Tracking works best on a distinct, well-lit plate. Retap to recalibrate.

Vertical reference Start center

Default: the bar’s starting center, not an ideal detected from your body. A coach can shift it toward midfoot. Offset is a measurement, not a pass/fail grade.

The demo shows how sideways drift appears against a straight reference.

A vertical line is a reference,
not a form verdict.

03 / REVIEW LIKE A COACH

Evidence before a cue.

Check the recording first: fixed camera, perpendicular view, entire plate visible. Select a rep, scrub to its greatest horizontal offset, then compare ascent and descent. Ask whether the bar stays close to the legs and whether the start and finish are consistent. The app measures the plate—it does not answer those body-position questions for you.

No “good form” score, injury prediction, velocity estimate or automatic lockout judgement. Small offsets can be tracking error or perspective. Use the video, not the number alone.
