I built and submitted a paid iPhone app in one evening. Not a game. Not a giant SaaS. Not some complicated app with logins, subscriptions, dashboards and a million moving parts. Just a simple little paid utility called Camp Amp. The idea came from spotting a boring App Store gap: Caravan, campervan and campsite users need to know if their electric hook-up will trip when they run things like a kettle, heater, fridge, microwave or hairdryer. That’s it. Very boring. Very useful. Exactly the kind of tiny app AI makes possible now. The process was basically: Find a niche problem Pressure-test the idea with GPT Write a proper build brief Use Codex to build the app Test it in Xcode Create the App Store copy and screenshots Submit it to Apple All in one evening. Then I used KlipZi.com to make the trailer/promo content for it. That’s the bit I think people are sleeping on. AI can help you build the thing. Then AI video can help you promote the thing. That used to be two separate skill sets, a developer, a designer, an editor and a load of time. Now one person can move ridiculously fast. I’ve put together a free playbook showing the process behind building a simple paid iOS app with AI in twenty four hours. No coding background needed to start. Just a Mac, Xcode, GPT, Codex, an Apple Developer account, and one small useful idea. Comment AI APP and I’ll send it over.
