Not ideal for
Users needing advanced motion tracking over timeThose requiring 3D body modelingApplications beyond human pose (no animal pose)Teams needing multi-user collaboration features
Angle fills a specific niche — exact angle measurement from video — with impressive simplicity. It is a great utility for anyone needing objective form feedback, though the lack of API and integrations limits automation use cases. For teams needing collaboration or advanced tracking, consider alternatives like Kinovea or Hudl Technique.
Skip Angle if Skip Angle if you need collaborative team features, cloud storage, API access, or tracking over time (e.g., progress dashboards) — Angle is a solo, client-side tool.

About Angle
FreeIntermediateNo APIWeb
Angle is a specialized tool for measuring body angles and poses with high accuracy. It targets fitness coaches, physical therapists, and sports analysts who need objective data on movement quality and range of motion. Using computer vision and pose estimation models, Angle analyzes video or live camera input to calculate joint angles, body alignment, and pose similarity against reference standards. What sets it apart is its focus on pixel-precise angular measurements rather than generic pose detection, enabling real-time feedback for form correction in exercises like squats, deadlifts, and yoga poses. The tool provides a simple web interface where users can upload videos or stream from a camera, mark keypoints, and instantly get angle values and visual overlays. It's designed for quick, repeatable assessments without complex setup. No cloud storage or team sharing; all processing happens client-side.
Behind the Verdict
Angle's strength is its laser focus: it measures angles and poses with pixel precision from video, without fluff. The interface is clean: upload a video or use your webcam, mark key joints, and get instant angle readings with visual overlays. It supports common exercises and lets you compare against reference poses, which is valuable for form correction. However, the tool lacks any cloud storage, team sharing, or API. All processing is client-side, so long videos may be slow, and export resolution may be limited in the free version. There are no integrations with fitness platforms or EHR systems, and no mobile app. For a solo trainer or therapist doing quick assessments, Angle is fantastic. But if you need longitudinal tracking, multi-user collaboration, or integration into a broader workflow, you will likely outgrow it quickly.

Real-world workflow fit
Concrete scenarios for the personas Angle actually fits — and what changes day-one when you adopt it.
Personal trainer
A client performs squats during a session; you record a short video with your phone and upload it to Angle.
Outcome: Within seconds, you get knee and hip angle measurements, visually overlay them on the video, and share the snapshot with the client for immediate form feedback.
Physical therapist
A post-ACL surgery patient performs a leg press; you capture video and compare knee range of motion against a baseline from last week.
Outcome: Angle calculates the angle difference and gives a pose similarity score, allowing you to objectively track rehabilitation progress without a complex motion capture setup.
Yoga instructor
During an online class, you use your laptop camera to demonstrate a warrior pose; students upload their own video for alignment check.
Outcome: You mark keypoints on their pose, compare to a reference, and provide specific angle adjustments — all during the class session.
Use Cases
- Measure knee angle during squats to ensure proper form
- Compare a patient's post-surgery range of motion against baseline
- Analyze shoulder angle in swimming stroke videos
- Provide real-time feedback on yoga pose alignment
- Assess deadlift back angle for injury prevention

Where the pricing makes sense
The company stage and team size where Angle's pricing actually pencils out — and where peers do it cheaper.
Angle is free, making it accessible to individual trainers and small clinics. There is no paid tier, so for larger teams or enterprises needing collaboration, you will need to look at paid alternatives like Kinovea or Hudl Technique.
Setup time & first value
How long it actually takes to get something useful out of Angle — broken out by persona, not the marketing-page minute.
For an individual user, setup is immediate: open the website, grant camera permission, and you can start measuring within 30 seconds. No account creation is needed. For a trainer working with clients, expect an additional minute per video upload and keypoint marking.
Switching to or from Angle
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
Migrating in
- →From manual goniometer: Simply replace physical measurements with Angle's video-based measurements for quicker, recorded assessments.
Migrating out
- ↗To Kinovea: Export CSV data from Angle and import into Kinovea for more advanced analysis (suggested workflow).
- ↗To Hudl Technique: Use Angle for quick measurements, then switch to Hudl for team sharing and long-term athlete tracking.
