Train Fitness

What Train Fitness does

Motra Inc. (formerly Train Fitness, rebranded in January 2026) is a Toronto-based, venture-backed fitness technology company that builds an iOS and Apple Watch application for automatic exercise detection and rep counting. The product is powered by Neural Kinetic Profiling™ (NKP), a proprietary AI/ML algorithm invented in 2020 by engineers and PhDs from Harvard University, the Indian Institute of Technology, and the University of Toronto. NKP processes accelerometer, gyroscope, orientation, heart rate, and EMG data captured by a wrist-worn smartwatch to recognize 470+ exercises (with a 1,000+ exercise library as of November 2025) and log reps, sets, weight, tempo, and progressive overload without manual input or video recording. The platform also offers AI-generated personalized workouts, smart recovery insights, custom templates, and an MCP-based integration with OpenAI's ChatGPT for conversational access to workout history.

The company operates a product-led growth model, distributing primarily through the Apple App Store with a 30-day free trial and subscription-based pricing (Motra Pro) for premium features. Additional monetization streams include a 50% student discount tier and a Corporate Wellness program offering tailored subscriptions for teams of 5 to 5,000 employees, providing a B2B extension to the consumer base. Supporting integrations span Apple Watch, Apple Health/HealthKit, Apple AirPods, social login (Apple, Facebook, Twitter), and third-party LLMs (OpenAI ChatGPT, Google Gemini). Motra has logged over 10.9 million workouts and is led by co-founders Andrew Just (CEO) and Antoine Neidecker (CTO). The company has raised approximately $3.5 million USD in total disclosed funding across a 2021 pre-seed, a 2022 round led by Calm/Storm VC, and a $2.5 million seed round in June 2023 led by Relay Ventures alongside Alumni Ventures, Anorak Ventures, BAM Ventures, Boost VC, Gambit Partners, Mana Ventures, Republic Capital, and Spacecadet Ventures.
