First Android app ever, built in under a dozen hours with Gemini

Never built for mobile, a parent of three, a busy life. Gemini guided the Kotlin architecture and the UI, and their first Android app was a real joy to build. Impossible a couple of years ago, they say.

Result A real joy to build, for a parent of three

Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.

What they did

Built their first Android app for a specific need over the holidays. Gemini helped them set up a Kotlin app with a sensible architecture, including dependency injection with Hilt, find the right Material3 components, and lay out a UI that looks decent despite their lack of design skills.

How it went

It took less than a dozen hours and was a real joy to build. As a parent of three with a busy life, they say it would simply have been impossible a couple of years ago.

Try it yourself with Gemini
I'm an experienced [language] developer but new to Android. Help me build an app that [does X]. Set up a Kotlin project with a sensible architecture (dependency injection, a clear split between UI and data), use Material 3 components, and explain each choice briefly. Build it screen by screen so I can run it on my phone as we go.
