A gait camera that measures, in your pocket
High-speed capture, slow-motion review, an on-device pose skeleton, 2D joint angles, and exports. Clients and video stay on the iPhone.
Every session labelled the same way
Choose the setting, the view and the footwear before you record. They are saved with the session, so you can compare like with like later.
- Treadmill with belt speed, or Overground
- Side, rear or front view, with a set-up hint for each
- Footwear: barefoot or the shoe model
Up to 240 frames a second
Gait Positive records with the iPhone main camera at the highest frame rate it offers, up to 240 fps. Fast events such as heel strike and toe-off stay sharp in slow motion.
- Frame rate saved with every session
- No microphone: video only
- Saved straight to the client's folder on the phone
Slow motion, skeleton, angles
Pose tracking runs on the iPhone and draws a skeleton on the video. Step to the frame you need and read the angle.
- Playback at 1×, ½, ¼ and ⅛, and frame step
- Points on hips, knees, ankles, heels and toes
- 2D knee and hip angles, and shank (tibia) angle to vertical
- Full-screen player
Video for the client. Data for you.
Share with the iPhone share sheet: AirDrop, Files, Mail or your records system.
- Video with skeleton: .mp4, same size and frame times as the original
- Data (CSV): one row per analysed frame, body points and 2D angles
- Original video, as recorded
- File names carry the date, setting and view, not the client's name
Every session with the right client
Familiar iPhone lists. Add a client, then keep every session under their name, newest first.
- Stored on this iPhone with iOS file protection
- No account and no cloud
- Delete a session or a client and the video goes with it
Screens recreated from the app's interface. Demo clients and drawn figures, not real people.
Side, rear and front
Side view for knee and shank angles through the stride. Rear and front views to watch the pelvis, knees and feet from behind or in front.
Gait Positive is a measurement and video tool. It does not diagnose. Clinical judgement stays with the clinician.
Planned, not built yet
We will add these after the beta. Clinic feedback sets the order.
Flags against usual ranges
Cadence, overstride, vertical oscillation, knee flexion at contact, pelvic drop and crossover, shown next to published usual ranges.
Side-by-side compare
Two sessions next to each other: shoes, orthoses, or rehab week 1 and week 6.
PDF report
Stills, angles and notes in one report for the client or the referrer.
Speed-matched normal curves
Joint-angle curves over the gait cycle, compared with published curves at a similar running speed.
Also coming: a Foot Positive 3D foot scan and a Gait Positive session, filed with the same client.
