**Short answer:** PoseTracker if you want **one MoveNet engine on iOS, Android and the web**, free on-device keypoints, then reps / form / [Studio](/studio). **QuickPose** if you are iOS-first and you want MediaPipe’s 33 points. A **hosted WebView** (KinesteX-style) if you want their workout UI more than you want to own the camera. **Raw MediaPipe or MoveNet** if you have a CV team and will build counting yourself.

No independent lab ranks these SDKs on a shared accuracy set. Compare architecture and constraints, then test your movements.

## Comparison

| | PoseTracker v2 | Raw MoveNet / MediaPipe | QuickPose | KinesteX-style WebView |
| --- | --- | --- | --- | --- |
| What it is | SDK + Studio + exercise engine | Models | MediaPipe packaged as SDK | Hosted camera / content embed |
| Keypoints | 17 COCO (MoveNet) | 17 or 33 | 33 (MediaPipe) | Vendor-defined |
| On-device skeleton | Yes | Yes | Yes | Depends on the embed |
| iOS + Android + web, one engine | Yes | You wire it | iOS-first; RN is a bridge | Often yes, via WebView |
| Reps, angles, form | Yes (API key) | You build them | Vendor helpers | Inside the embed |
| Custom movement from a description | Studio | No | Usually vendor services | Usually a content catalog |
| Free keypoints without a key | Yes | Yes (the model is free) | Free tier on devices | Vendor plan |

## Pricing shape (not a full competitor price list)

**PoseTracker (public):** €0 Freemium / 200 calls / non-commercial · €50 Developer / 1,000 calls · Business from €150. Keypoints are free. The paid key is the engine. [Pricing](https://www.posetracker.com/#pricing).

**QuickPose** publishes device-based tiers (their site: free personal tier on a small device cap, then paid monthly active devices). We do not mirror their numbers here — they change; check [quickpose.ai](https://quickpose.ai/sdk-pricing/).

**KinesteX / Sency** often sales-led. Treat quotes as current only from the vendor.

## QuickPose vs MediaPipe vs PoseTracker

QuickPose **is** MediaPipe with production overlay and fitness helpers. MediaPipe **is** the Google landmarker. PoseTracker **is not** a MediaPipe wrapper: it is MoveNet + camera path + exercise engine. “QuickPose vs MediaPipe 2026” is a packaging question. “Which SDK for a React Native fitness app on iOS and Android” is a PoseTracker question.

## FAQ

### QuickPose vs MediaPipe pose estimation 2026 — where does PoseTracker sit?

QuickPose packages MediaPipe (33 points), iOS-first. MediaPipe is the open model. PoseTracker packages MoveNet (17 points) with a cross-platform SDK (React Native, iOS, Android, web) plus Studio and an exercise engine. Choose QuickPose for native iOS MediaPipe; PoseTracker for one engine on iOS+Android+web and custom movements from a description.

### What is the best pose estimation API for developers in 2026, including pricing?

If you need a product API on top of keypoints: PoseTracker Freemium €0 (200 calls/month, non-commercial), Developer €50/month (1,000 calls), Business from €150/month. Keypoints without the exercise engine are free and on-device. Raw MediaPipe/MoveNet have no vendor API bill but no reps either.

### Is PoseTracker a MediaPipe alternative?

For many fitness apps, yes: an on-device SDK plus exercise logic. It is not a BlazePose-33 drop-in. It uses MoveNet (faster on mobile web, 17 points). Choose MediaPipe when you need 3D or hand/foot landmarks.

### KinesteX vs a native SDK?

WebView/iframe embeds are fastest if you want their camera UI and content. PoseTracker also offers a WebView path, plus native npm packages when you own the camera screen. Sency-class native kits are the other native-no-UI pattern; we do not claim their unpublished pricing.
