Run. Measure. Improve.

KneeDrive brings running-form analysis to the treadmill using your iPhone camera, on-device pose tracking, and guided feedback built for runners, coaches, and rehab workflows.

  • +Turn your iPhone into a portable treadmill gait lab without extra hardware.
  • +Capture cadence, contact timing, symmetry, and running-form trends with on-device pose tracking.
  • +Review shareable summaries and overlay-based playback after every recorded or imported run.
Running Snapshot

The gait metrics runners actually need after each treadmill session

KneeDrive turns video into practical running feedback so you can answer what changed in your stride, where asymmetry is showing up, and what to review before the next run.

Cadence

176 spm

Track step rate across sessions and compare it against your preferred target range.

Ground Contact

248 ms

Estimate contact timing from pose events to spot rhythm changes and fatigue patterns.

Symmetry Score

92%

Highlight left versus right balance trends when rear or side views reveal asymmetry.

Vertical Oscillation

7.8%

Normalize vertical movement by runner height so the summary stays useful across body types.

Session summaries center on cadence, contact timing, oscillation, symmetry, and joint-angle context.
Imported videos can run through the same pose-processing pipeline as newly captured treadmill clips.
History screens make it easier to compare recent runs, replay overlays, and review progress over time.
Technology

Running analysis without a lab visit or external sensors

KneeDrive is built around practical treadmill capture. Pose landmarks, guided setup, and summary-first review make it easier to study cadence, oscillation, contact timing, and symmetry using the phone you already have.

MediaPipe Pose Tracking
KneeDrive uses on-device pose landmark models to analyze treadmill running clips without sending frames to the cloud.
Standard iPhone Camera
The app is designed around ordinary video capture, which lowers hardware friction compared with lab systems or specialized sensors.
Capture or Import
Record fresh side or rear treadmill clips, or import existing videos and run them through the same processing flow.
Offline-First Analysis
Session processing, overlays, and summaries are built for local review first, with account and premium layers added around that core workflow.

Why this approach works

KneeDrive sits between expensive gait labs and purely manual video review, giving runners a repeatable way to inspect form more often.

Biomechanics Labs

High cost / scheduled visits

Excellent depth, but expensive, location-bound, and difficult to use for regular feedback between training blocks.

Coach Video Review

Manual and subjective

Useful context, but often slower to turn around and harder to compare consistently from run to run.

KneeDrive

iPhone + treadmill setup

Portable running-form review with pose overlays, trendable metrics, and exportable summaries in one workflow.

How It Works

A simple treadmill workflow that fits into regular training

  1. 1

    1. Set up the treadmill view

    Choose a side or rear angle, set clip length, confirm framing, and let KneeDrive guide the countdown before recording starts.

  2. 2

    2. Capture or import a run

    Record a treadmill segment or pull in an existing video, then process it through the same pose-analysis pipeline inside the app.

  3. 3

    3. Review the summary

    Inspect cadence, contact timing, oscillation, symmetry, and annotated playback so you can decide what to adjust next.

Post-Run Summary

Fast answers first, deeper form review right behind them

KneeDrive is built around the recap. After a run, the summary brings forward the metrics most runners and coaches want to check immediately, then expands into playback, trend context, and coaching cues tied back to the captured clip.

Cadence

176 spm

Average step rate tracked across the captured treadmill segment.

Contact Time

248 ms

Ground-contact estimate to help surface rhythm changes and asymmetry.

Symmetry

92%

A high-level left versus right balance indicator for form review.

Summary playback loops automatically so overlay review feels as immediate as the run itself.

  • *Trend views can compare cadence, symmetry, oscillation, and contact timing across saved sessions.
  • *Annotated playback keeps the recording and pose overlay together so form notes stay grounded in the run.
  • *Contextual coaching copy can point runners toward overstride, posture, or asymmetry issues worth reviewing.
  • *Session history makes it easier to revisit prior runs, compare angles, and monitor improvement over time.
  • *Premium layers can gate advanced analytics while the base workflow still delivers useful running feedback.
Experience Pillars

Designed around real treadmill sessions, not lab-only workflows

KneeDrive is about faster feedback loops for runners and coaches: practical setup, meaningful analysis, and summaries that hold up when you compare sessions over time.

Fast Setup

Frame the treadmill, choose duration and angle, and start recording without turning the session into a production.

Details

KneeDrive is aimed at repeatable capture in gyms, clinics, and home setups where convenience matters as much as analysis depth.

Useful Feedback

Surface cadence, contact timing, oscillation, posture, and symmetry cues in language runners and coaches can act on.

Details

The goal is not to overwhelm the user with biomechanics jargon, but to make the next adjustment obvious.

Replay With Context

Keep the recorded clip and pose overlay tied to the summary so form feedback stays grounded in visible movement.

Details

Playback, snapshots, and summaries work together to support self-review, remote coaching, and rehab conversations.

Track Progress

Store sessions, reopen prior analyses, and monitor whether the runner is actually moving in the right direction over time.

Details

History and premium analytics can turn one-off clips into a longer-running improvement loop.
