Shipped an iOS app solo with Cursor, zero coding experience before February

10 years as a 3D artist, never touched Xcode or written a line of code before this year. In February I opened Cursor and just started typing what I wanted to build.

7 months later, backend on Cloudflare Workers, iOS app in SwiftUI, multi-model AI routing (GPT, Claude, Gemini), all written and shipped through Cursor. Launched on the App Store, now live on Product Hunt today.

Biggest surprise for me: the hard part was never writing the code, Cursor handled most of that. The hard part was learning to think in systems, architecture, what breaks what, how to debug when something goes wrong three layers deep. That took actual time.

Curious how far others here have pushed it. Anyone shipped something with real backend complexity, not just a CRUD app or landing page?

Thremark - Your AI reaches out. Not the other way around.

Most AI waits for you to open the app. Thremark doesn't. Save something once as a Mark, and it shows up in every future conversation on its own. No prompts. No repeating yourself. From day one, Thremark can write to you first, about something that actually matters to you. GPT, Claude, Gemini never do that. Voice, files, web search. All models in one chat that already knows you. Built around Memory Recalls, the feature that makes your AI reach out first.
