What is Riven?

Riven is a performance-focused fitness application designed to turn an Apple Watch into a sophisticated muscle fatigue sensor. By utilizing the device’s internal motion and heart-rate sensors, the app tracks lifting speed and repetition consistency to quantify when a user has reached true muscle failure.

Why Founders Need This

For high-performing founders, gym time is often a fixed variable in a busy schedule. Riven eliminates the guesswork involved in training intensity. By providing a ‘failure score’ (0-100), it allows users to optimize their sessions for maximum hypertrophy and strength gains without the risk of overtraining or ineffective light sessions.

How It Works

  • Hands-free Tracking: Auto-detects over 30 exercises including bench press, squats, and deadlifts.
  • Velocity-Based Training: Measures the loss in repetition speed, which is a scientifically validated metric for muscle fatigue.
  • Real-time Feedback: Uses a color-coded interface to alert users when they are hitting optimal intensity zones.

Pricing

Riven operates on a subscription model: Pro plans start at Rs 900/month or Rs 7,900/year, with unlimited tiers reaching up to Rs 19,900/year.

Alternatives

  • Hevy: Best for community-driven tracking and social workout logs.
  • Native Fitness Apps: Best for high-level caloric and heart-rate monitoring without specific muscle-load depth.
