## PoseTracker API

PoseTracker solves a specific problem: most digital fitness products are blind coaches. They play a video, hand out a plan, and never look at the person actually moving. PoseTracker gives the product eyes by running pose estimation on the phone itself, so a camera feed becomes 17 COCO keypoints in real time without uploading video anywhere.

The stack is built for shipping fast. A React Native package (works in Expo Go) and a browser JavaScript build both use the same on-device MoveNet engine, so keypoints are free and require no API key. When an app needs semantics on top of raw coordinates — is that a valid squat rep, what is the knee angle, does this push-up meet form criteria — an optional API key unlocks a hosted engine that returns reps, angles and a form score. A classic WebView or iframe integration remains available for teams that already embed a web view.

Beyond reps, the platform offers built-in tools including a back flexibility test, a flexibility analysis tool with automatic angle detection, and a pose comparison system that scores a user against a reference position. Browser benchmarks published by the team put MoveNet Lightning around 51 FPS on an iPhone 12 and 34 FPS on a Pixel 5. On-device inference means the video stream never leaves the device, which simplifies privacy and cuts bandwidth for fitness and rehab use cases.

**Pricing & Plans:** Freemium with a paid developer tier. The free plan covers keypoints at no API key plus up to 200 tracking API calls per month and 100 AI assistant credits, restricted to non-commercial use. The Developer plan is €50 per month with 1,000 tracking API calls included and commercial use, and a tailor-made Business plan is available on request.

- **On-device MoveNet keypoints:** 17 COCO keypoints stream directly on the phone or in the browser with no API key and no video upload.
- **Rep, angle and form engine:** An optional API key returns repetition counts, joint angles and a movement form score for exercises like squats and push-ups.
- **React Native and web SDKs:** One engine with three integration paths: native React Native (Expo Go), browser JavaScript, and a WebView or iframe embed.
- **Built-in motion tools:** Ready-made back flexibility test, flexibility analysis with automatic angle detection, and pose comparison against a reference position.
- **Custom movement support:** Describe a movement, context and stack and the in-page assistant returns a React Native, Expo or web snippet on the same engine.

**Strengths:** Keypoints run on-device, so video never leaves the phone; Free tier with 200 API calls per month makes prototyping inexpensive; One engine covers React Native, iOS, Android, web and low-code embeds; Additional form scores, angles and flexibility tools go beyond raw keypoints

**Limitations:** The free tier is limited to non-commercial use and a strict monthly call cap; Semantic outputs such as reps and form scores require an API key and credit balance; On-device accuracy depends on phone hardware, lighting and camera framing

## Roboflow

Roboflow is a computer vision platform built for what it calls AI for the physical world. Its goal is to move vision projects from idea to production without stitching together a dozen separate tools. The platform covers the full lifecycle: collecting and labeling image data with AI-assisted annotation, training and comparing models, assembling multi-step workflows, and deploying inference in the cloud or on edge hardware.

The annotation layer uses frontier models and custom filters to label thousands of images quickly, which drastically cuts the most tedious part of a vision project. From there, teams train models, evaluate them, and then build Roboflow Workflows that combine object detection, tracking, motion detection, line counters, and notification blocks into a single pipeline. This makes it possible to, for example, detect defects on a production line, count items on a conveyor, and send an alert when a threshold is crossed.

Roboflow also leans heavily into developer ergonomics. It maintains popular open-source projects such as supervision, inference, RF-DETR, trackers, and notebooks, and exposes an MCP server so coding agents like Claude Code, Cursor, Codex, and Gemini CLI can build deployable vision applications. Deployment targets span cloud inference and edge devices, and the customer base includes more than half the Fortune 100, with published case studies in rail logistics, building materials, and consumer goods. A free tier lets individuals and small teams start building before committing to a paid plan.

**Pricing & Plans:** Roboflow offers a free tier that the company says is enough to start building, and paid plans for more usage and team features. Larger enterprise and high-volume deployments are priced through a sales conversation, so exact figures depend on your project and should be confirmed on the pricing page or with Roboflow directly.

- **AI-assisted annotation:** Label thousands of images in minutes using frontier models and custom filters, then curate datasets for training.
- **Visual Workflows builder:** Combine detection, tracking, and logic blocks to orchestrate actions, update databases, and connect to industrial systems.
- **Cloud and edge deployment:** Run high-speed inference in the cloud or on edge devices, processing live video and images wherever the application lives.
- **Roboflow Agent:** Get into production quickly with an agent that sees the world, understands what is happening, and triggers actions.
- **Developer and open-source tooling:** Connect coding agents like Claude Code, Cursor, Codex, or Gemini CLI to the Roboflow MCP server, and build on open-source projects including supervision, inference, RF-DETR, and trackers.

**Strengths:** Covers the whole vision lifecycle in one platform, from annotation to deployment; AI-assisted labeling dramatically speeds up dataset preparation; Roboflow Workflows chain detection, tracking, and actions without heavy custom code; Deployment in the cloud or on edge devices, with live video support
