Indie software studio — Tokyo

Building software that actually helps.

I make macOS, iOS and Android apps — focused on tools, apps and games that actually help, or at least are fun ;)

Projects

My Apps & Services.

A fast, reset-proof logger for indoor climbers.

One-tap bouldering tracker for gym climbers — log attempts across V-scale, Font and Japanese kyu/dan, watch your pyramid fill in, and share session cards. Offline-first with optional cloud sync.

Plan together. Celebrate forever.

An AI wedding planner for couples — shared budget, guest list, RSVP website, and an assistant that handles the small decisions so the day stays the big one.

Five tiny duels, one rematch button.

A faithful rebuild of the 2016 indie hit — five mini-games, async multiplayer, Firebase backend. Made in Flutter + Flame.

Disk space, finally legible.

A native macOS app that scans drives at full speed and shows you exactly what's taking up space — with a treemap that you can actually read.

Your photo library, organised at last.

A Mac app for bulk-cleaning, deduplicating and exporting your photo library. Sandbox-safe, fast, and respects originals.

macOS

Open Source

My Packages.

Libraries I maintain and give away — used in production apps around the world.

A drop-in emoji picker for Flutter.

An emoji picker widget with 1500+ emojis across 8 categories, customizable, localized, and running on every Flutter platform — Android, iOS, web, macOS, Windows and Linux.
