I Built An Ios App That Turns Mandalart (9x9) Into Gtd Actions (v1.0)

You know the Mandalart? It's the famous 9x9 grid method used by Ohtani Shohei. It's amazing for visualization. You write your core goal in the center, and 64 sub-actions around it.

But there's a problem. It stays on the paper. I realized that while Mandalart is great for planning, it sucks for execution. You can't carry a huge A3 paper everywhere. And looking at 81 boxes every morning is overwhelming.

So I decided to build an app that bridges the gap between Mandalart (Planning) and GTD (Execution).

Wait, did I mention I'm not a developer? Actually, 90% of this app was built using Claude Code.

For the finishing touches (optimization, automation, and even this blog post!), I used Gemini CLI, Codex, and Antigravity.

If you are interested in this "Vibe Coding" workflow, let me know in the comments!

I just launched it on the App Store. I'd love to get feedback from fellow devs on the UX. Is the OCR fast enough? Is the "Daily View" intuitive?
