Why I built an AI fitness coach for a market nobody was looking at

Most AI fitness tools are built for the US market in English. I built Apex Pulse Pro for Bulgaria first a small, skeptical market where people don't easily pay online.

The data surprised me: 93% mobile traffic, 71% women, 35-54 age group. I thought I was building a fitness app. The market told me it's actually a weight loss tool for middle-aged women who are tired of copy-paste programs.

Built entirely solo. Code, design, ads, emails, deployment mostly from my phone. Deployed on Railway, email via Resend, payments via Stripe.

Today is launch day. Happy to answer anything about the product, the stack, or what it's like building solo in a non-English market.
