Fitloop

Branded workout tracking with structured plans and a real coach pathway

Fitloop is a workout-tracking and coaching app under your brand. It captures sets, reps, weights, and notes; renders structured plans (linear progression, percentage-based, conjugate); and gives a coach a clean view of every athlete's compliance and progress. It runs on the Realtime Mobile Stack because the user logs sets at the rack and the coach watches compliance from anywhere.

Key features

  • In-workout logging (sets, reps, weight, RPE, notes) with rest timer
  • Plan authoring tools for coaches (linear, percentage, conjugate, RPE-based)
  • Auto-progression rules (PR-based, 1RM-based, percentage-based)
  • Exercise library with video demonstration (white-label friendly)
  • Coach dashboard with athlete compliance, missed sessions, PR feed
  • In-app messaging between coach and athlete with form-check video upload
  • Apple Health and Google Fit integration for cardio + sleep import
  • Subscription billing per athlete or coach-paid package via RevenueCat

What you get

Fitloop ships as branded iOS + Android apps and a coach web dashboard under the customer’s brand. The exercise library, plan templates, and a starter set of demo videos seed during onboarding. RevenueCat handles iOS / Android subscription billing cleanly; Apple Health and Google Fit data flows in on day one.

Sample customer story (placeholder — illustrative only)

A 25-coach strength-training program licensed Fitloop to consolidate athletes who had been spread across TrainHeroic, Google Sheets, and personal training spreadsheets. After three months in market, average per-coach weekly retention rose from 71% to 86% — most of the lift came from the in-app form-check video flow keeping athletes engaged with their coach between sessions, not from anything mechanical Fitloop did differently.

What’s NOT included

  • Cardio-first endurance plans (Zwift / TrainerRoad shape). Possible as a customization, but the out-of-the-box product is strength-shaped.
  • Nutrition / macro tracking. Out of scope; integrate with MyFitnessPal or a partner.
  • Wearable hardware sales. Software-only.
  • AI coach generation. Plans are authored by a human coach. AI plan generation is a paid Pass-2 customization.
