Who it's for

Solo developer or 2-person team with basic fitness knowledge (not required) and ability to integrate AI APIs. Sells to fitness-curious Africans aged 18–45 with smartphones and disposable income in USD/GHS/NGN.

How to build it

1. Build a simple onboarding flow (age, weight, fitness level, goals, available equipment) that feeds into an LLM prompt to generate weekly workout plans as text/video links 2. Add a progress tracker: daily check-in, log workouts, capture body metrics (photos, weight) — store in Postgres 3. Integrate Stripe/Paystack for subscription (weekly/monthly/yearly tiers; free tier with 1 plan/week) 4. Build a basic push notification system to remind users to work out; use daily engagement as retention lever 5. Add video library: film 20–40 short demo videos of common exercises, or license/embed existing fitness creator content under fair use for guidance

No gym access needed = huge TAM in Lagos, Accra, Nairobi. LLM-powered personalization is cheap to build; your cost per user is near-zero after initial API spend.
