The Challenge

Most fitness apps lose users in the first month. The startup wanted to break that pattern:

  • Personalize plans to each user's goals, history, and equipment
  • Adapt as users progress instead of static templates
  • Build a habit loop with streaks, social, and notifications
  • Integrate cleanly with HealthKit, Google Fit, and major wearables
  • Stay snappy on mid-range devices

Our Solution

We built a coaching experience that feels personal — because it is:

Adaptive AI Coach

On-device and cloud models that adjust workouts based on performance, recovery, and feedback.

Nutrition Companion

Smart logging and meal suggestions tied back to each user's training plan and goals.

Social Habit Loops

Streaks, friend-group challenges, and gentle nudges that make consistency feel like a game.

Wearables & Health Data

Deep integration with HealthKit, Google Fit, and major wearables for richer signals.
