From the icon grid to the App Store, alone.

I'm Hoang Minh Duc. I design, build, and ship small iOS apps by myself. Everything I've published is below, all of it built around AI that helps and then gets out of the way.

Novel AI — AI Story Generator

Rabi, a co-author for the story you keep meaning to write.

Rabi turns a prompt into a chapter. Choose a genre and a tone, write the opening line, and let the AI carry the scene forward — then rewrite, expand, or cut anything it hands back. Nothing is final until you say so.

Finished stories get generated illustrations and a matching soundtrack, so a draft reads like a book rather than a text box. Publish to the reader community when you're ready, or keep everything to yourself.

  • Draft, rewrite, and expand with AI
  • Genre and tone presets
  • Illustrations generated per scene
  • Background music by mood
  • Write offline, on iPhone or iPad
  • Share stories with the community

Just launched Maps & weather

Fish AI — Smart AI Fishing Map

A fishing map that reads the water before you cast.

Fish AI weighs weather, wind, and water conditions against a detailed fishing map, then points you at the spots most likely to be productive that day. It works from shore, a kayak, or a boat.

Navigate by GPS, mark the places that keep paying off, and log every catch with photos and notes. Maps stay downloaded for the parts of the water where the signal disappears — usually right where you need them.

  • AI spot recommendations
  • Detailed lake, river, and coastal maps
  • Forecasts, wind, and live conditions
  • GPS navigation and saved routes
  • Offline maps for remote water
  • Catch journal with photos and notes

About

Every part of these apps comes from the same desk: the icon, the interface, the code behind it, the screenshots on the store page. That's the constraint, and it's also the point — nothing ships that I don't understand end to end.

I like apps that stay small. AI earns its place when it removes a blank page or a guess, and wears out its welcome when it starts making decisions for you, so I keep it firmly in the first category.

Both apps are free to download. Subscriptions cover the parts that genuinely cost money to run — model calls, maps, storage — and nothing else is locked behind them for the sake of it.

If something is broken or a feature is missing, write to me directly. The address below reaches me, not a support queue, and I read everything.
