Additional info
Turnkey iOS app in Turkey's KPSS exam market (~2M+ candidates/year). ~$1.2K MRR, monthly+annual (RevenueCat), no backend. Proven cheap acquisition: ASA ~$0.15 & Meta ~$0.10 CPA — creatives + campaign setup included. Clean SwiftUI, ASO-ranked. Scale for 2027.
"Selling to focus on other apps in my portfolio — this one deserves an owner who'll ride the yearly exam cycle. It's a clean, recurring-revenue iOS asset in Turkey's KPSS market (~2M+ candidates/year), with no backend to maintain and a dirt-cheap, already-dialed-in ASA engine. Monetization, analytics and ASO are live, and the paywall was just optimized. Priced to move for a quick, friendly handover — an ideal bolt-on for an edtech or app-portfolio buyer."
