Winners Built With Flutter

A composition aid for school music classes. A student describes in their own words the song they want to make, and the AI proposes chord progressions and melodic techniques that could fit. It stops short of writing the piece itself: students try options and choose, bringing individual creativity into uniform-feeling lessons.

An agent for foreign visitors caught in an earthquake or typhoon in Japan, unable to read the warnings or tell where to evacuate. Drawing on official meteorological and geospatial data plus preparedness guides, it delivers alerts, shelter directions and ready-to-send safety messages in the user's own language.

Upload one photo of the furniture you want to build and this web app works out the parts, generates a 3D model, lays out the cutting and assembly steps, and exports a plan as a PDF. It targets DIY beginners who cannot draw plans and hesitate over materials, so they can start work already holding instructions they trust.

An app for experiencing race day before it arrives. It cross-references the course GPX, the weather and the runner's goals and training history, then works out which points to watch, how to pace and where to drink. The advice comes back as a generated video with captions, helping runners picture the course and judge well.

An end-to-end teaching assistant for new English teachers at tablet-equipped junior high schools. It spans lesson prep, the class itself, automatic quiz generation and grading, and per-student feedback. Classroom audio is transcribed so questions match what was taught, and wrong answers are analysed class-wide.

A phone app for travellers stuck in front of an unreadable menu. OCR pulls dish names and prices from a photo, then adds a translation, a short explanation and a generated image so you can picture the taste and look. Pick a dish and the app renders your order in the local language to show the waiter, and it keeps past lookups.

Pregnancy brings changes day by day, and memory alone makes them hard to describe at a check-up. BLOOMS is an iOS and web app that takes over the record-keeping: generative AI responds to the notes and photos a user leaves, suggests keywords to look things up, and summarises a stretch of entries to bring to an appointment.

A web app for households where two working parents and the price of picture books squeeze out bedtime stories. Pick an age, a script, a length and a genre, and the AI writes a story, illustrates it and reads it aloud. At around a dozen yen per episode, a fresh book can match the child's stage and interests every time.

An AI coding agent aimed at the cost and time a mobile MVP takes. Describe the app you want in plain language and it writes Flutter code you can preview on the spot, and when the build breaks it repairs its own errors. Finished apps ship to Firebase in one click, letting a solo developer cycle through prototypes quickly.
