Live & On-Demand Workout Streaming

Instructor-led video classes with leaderboards, chat rooms, and Chromecast / AirPlay support.

The retention loop

Fitness apps are not won on features. They are won on whether someone is still using it in week six.

  • 01

    Onboard

    A first session inside two minutes, before the motivation that drove the download decays.

  • 02

    Plan

    A programme that adapts to what was actually completed, not what was scheduled.

  • 03

    Track

    Sessions, food and biometrics in one record, whichever device wrote them.

  • 04

    Nudge

    Notifications tied to the user's own pattern rather than a fixed hour of the day.

  • 05

    Show progress

    The reason anyone still opens the app in week six.

The wearable is optional now

On-device vision now does form correction from a phone camera, which takes the wearable out of the onboarding path entirely. At the same time health data is moving under stricter consent rules. We keep the sensing layer swappable and the consent explicit, so neither shift forces a rebuild.
