The Gift Fitness

The problem

Independent trainers were running real businesses out of Instagram DMs, spreadsheets and cash apps — no storefront, no scheduling, no way for new clients to find and compare them. Clients, meanwhile, had no accountable way to buy training and stick with it.

A fitness marketplace with two very different jobs

One app serves two audiences. Clients get an e-commerce experience: search trainers, exercises and challenges, compare packages, book and pay in-app. Trainers get a business cockpit: an offerings carousel for their Packages, Plans and Challenges, a client roster with medical intake and meal and weight logs, attendance check-off, and a weekly earnings chart with projected totals.

Gamified accountability with real stakes

Paid challenges are the signature mechanic — entry fees, prize pools, live countdowns and participant stacks. "Lose It or Lose It: $250 prize, $15 entry, 28 participants" is a retention engine and a revenue stream in one card.

The stack and the look

A single Flutter codebase ships to iOS and Android. Firebase coordinates bookings between both sides, Algolia powers typo-tolerant discovery across three search verticals, and Stripe handles payments and payouts. A gym-native dark UI — near-black surfaces, heavy-overlay photography, one electric lime accent that always points at money and action.
