Who it's for
Solo or 2-person team with interest in health tech; target: women managing a chronic condition (menopause, PCOS, endometriosis, etc.) who pay out-of-pocket because local healthcare doesn't address it well.
How to build it
1. Pick ONE underserved female health condition common in Nigeria/Africa (menopause, fibroids management, fertility tracking beyond basic apps).
2. Build a mobile-first web app: symptom tracking dashboard, educational articles/video library, community forum (moderated), 1-on-1 expert chat (async, via WhatsApp or in-app).
3. Recruit 3–5 local health professionals (nurses, nutritionists, doctors) to answer questions; pay them per response or monthly retainer.
4. Launch free tier (tracking only); paid tier ($5–15/month) unlocks expert access, personalized plans, ad-free community.
5. Grow via Facebook/TikTok ads targeting women 40–60 in Nigeria, Kenya, Ghana; use testimonials and before/after tracking screenshots.

Your edge as a builder from anywhere
Women in Nigeria/Africa spend money on health solutions when local public healthcare fails them. You speak the language, understand local payment methods (Paystack, bank transfer, airtime), and can hire expert advisors cheaply. No inventory, no shipping, low churn if you build real trust and community. Global SaaS health apps often ignore local context (diet, climate, access to medication); yours
