Who it's for
Solo developer or 2-person team building a fitness SaaS; selling to working professionals aged 25–45 in Nigeria, Ghana, Kenya who have phones but limited gym access
How to build it
1. Build a simple onboarding flow: collect fitness goal, current activity level, available time (5/15/30 min), and equipment at home via web form
2. Create a workout database (~200 routines: bodyweight, dumbbells, resistance bands) tagged by duration, difficulty, and goal—store in PostgreSQL
3. Build an AI prompt layer (Claude API or similar) that generates a weekly plan (7 workouts) based on user inputs, then cache/refine for speed
4. Add a progress tracker: simple weight/measurement inputs, before/after photo uploads to S3, weekly check-in notifications via email
5. Launch with email+WhatsApp community, freemium model (3 free plans/month), then charge for unlimited access + custom coaching upsell

Your edge as a builder from anywhere
Nigeria has 200M+ people, high smartphone penetration, and almost no local fitness app that works offline-first with Nigerian payment methods (Flutterwave). Build one with WhatsApp integration for support, price it in NGN, and launch with micro-influencers (fitness TikTokers, Instagram trainers) who have no good affiliate programs locally—you become theirs. No inventory, no logistics, pure softwar
