Train Fitness

Train Fitness (recently rebranded as Motra or WhisperHeart in some contexts) is a verified Y Combinator (W21) startup with a legitimate AI-powered Apple Watch app for automatic workout tracking. External verification confirms a $2.5M seed round at an $11M valuation and approximately 10k+ weekly active users, generating estimated annual revenue of ~$1.8M. However, the project submission contained significant inaccuracies, most notably the claim that 'most people have used my product' and listing 'market cap' instead of revenue. While the technology is highly innovative and useful for its niche (strength training), the score is penalized heavily by the poor quality and hyperbolic nature of the submission data, as well as its relatively small user base compared to established reference benchmarks.
