About
Native iOS app (Swift) that translates a video into another language and dubs it with an AI voice. Live on the App Store since June 29, 2026. I built it for an investor, so the UI, onboarding and paywall are polished, and it is localized into the main App Store languages.Sales (App Store Connect): July 2026 $102, August 2026 $155, September 2026 $47, October 1-13 $20. Total since launch: $324. Traffic is 100% organic, paid ads were never run. Running costs are about $5/month.The new owner gets the app transferred to their App Store account, the full source code, the RevenueCat project and the backend.App Store: https://apps.apple.com/th/app/ai-dubbing-video-translator/id6760102361Who uses it: Content creators and small businesses who want their videos in other languages. Paying users buy weekly/monthly/yearly subscriptions or token packs. New customers in RevenueCat: May 31, June 43, July 109, August 70.Tech stack: Swift (native iOS), RevenueCat for subscriptions, backend on VULT, dubbing through the HeyGen API. The dubbing API can be swapped for a cheaper provider to improve margin.Challenges: Revenue is small and comes only from organic App Store traffic, so it moves from month to month. Paid acquisition has not been tested yet.Why I'm selling: I'm selling to focus on other projects. The app is finished and stable, costs about $5/month to run, and has never had paid marketing, so there is clear room to grow with Apple Search Ads, TikTok or ASO. I can help with the App Store transfer and share what I would do next.Handover: App transfer to your Apple developer account (ratings and reviews stay), source code, RevenueCat project and backend access. I'll walk you through the setup.

sounds interesting. what languages are supported?
impressed by the tech behind the AI dubbing, what’s the stack and how does it handle different accents?
stack looks cool with swift, what’s the backend like for the translations and voice?
pretty neat idea for reaching a wider audience, but it needs more language options for better market fit.
