This is a profitable iOS subscription app in the fast-growing AI writing space. It helps students, professionals, and content creators turn stiff AI drafts into natural, human-sounding writing in one tap. The product is simple, highly useful, and easy for users to understand, which has helped it build strong ratings and recurring revenue. Launched in late 2024, the business has grown entirely through organic demand with no ad spend. It now runs almost passively, with high margins, low ongoing costs, and a revenue base driven mostly by renewals, giving a buyer a clean, efficient business with clear room to scale. Key Highlights ✅ $116.7K TTM revenue, $96K TTM profit, 82% margin, and 84% YoY growth ✅ ~$9.4K MRR from ~900 active subscriptions, with 72% of revenue from renewals ✅ 4.6★ rating from 1,250+ reviews and only ~0.5% refunds ✅ Zero weekly hours required and no paid marketing used to date ✅ Clear upside through Android launch, paid acquisition, ASO, localization, and paywall testing
1) Paid acquisition, which has never been tried: realized LTV per install is ~$1.4-2.2 gross, so Apple Search Ads has room to be profitable. 2) An ASO refresh: the app has not been updated since Nov 2024, so new screenshots, keywords and an SDK update are an easy way to win back search ranking. 3) An Android launch from the existing Flutter codebase. 4) Localization: the app is English-only today and 81% of revenue comes from the US. 5) Paywall tests: free trial, intro offers and annual-plan positioning (conversion is already 7-8% without a trial).
