Armbrella

locationpinUnited Kingdom

Armbrella is a mobile-first fitness & wellness platform where everyday users discover certified coaches, subscribe to tiered workout/nutrition plans, track daily progress (steps, water, calories, weight), join challenges, and share short videos in a safe, moderated feed while coaches run their business end-to-end with client plans, sessions, messaging, and a revenue dashboard. A single web admin reviews coach credentials, moderates content, manages subscriptions and reports, and oversees transparent payouts. Payments are simple: users buy plans via App Store/Play; coaches are paid monthly via Stripe Connect with clear ledgers.

Problem Statement

Building Armbrella meant combining fitness tracking, social content, and coaching monetization—each with unique technical risks. Finding a free, compliant music API suitable for workouts was non-trivial. Moderating a social feed at scale required AI-based safeguards to prevent unsafe content. AI calculators had to be accurate and interpretable, not just technically correct. Synchronizing multiple daily metrics (steps, calories, weight, water) into real-time graphs added further complexity.

Solutions

We evaluated and integrated compliant audio sources suitable for fitness use cases. An AI-powered moderation layer was introduced to flag and manage unsafe content automatically. Wellness calculators were tested against edge cases to ensure realistic outputs. We built a robust aggregation layer to sync fitness data in real time, ensuring dashboards and graphs always reflected accurate user progress—making Armbrella reliable for both users and coaches.
