Making great apps with love and robots.

Supaa is the independent app studio of Morimoto & Company Oy in Helsinki. We design, build and ship our own products for web, iOS, Android and Mac — from a club management platform in production to a family shopping list in beta and a pipeline of new ideas.

Our apps

Six products, from live platform to first prototype.

Every product is designed, engineered and tested in house, with an emphasis on performance, privacy and longevity. Status labels show exactly where each one is today.

SupaDojo

Martial arts club management

In production · pilot

One place for a martial arts club to run members, practices and events. Members see their next keiko and let the club know they are coming with one tap; club admins manage memberships, schedules, attendance and club communication without spreadsheets. Now rolling out with a pilot club in Finland.

Clubs, memberships and approvals
Events, recurring practices, ICS sync
Attendance reports and funding exports
Club feed, groups and moderation
Passkeys and privacy-first onboarding

Ostoslappu

Shared family shopping list

Beta · TestFlight

A native iPhone shopping list for the whole household. Add items by typing, voice, barcode or straight from a recipe, shop aisle by aisle in store mode, and learn from your purchase history. Shared over iCloud — no account needed — with optional AI assistance.

Geo Boi

Geography game for curious kids

Live · free

A bilingual geography adventure for school-age players. Recognise countries from partial maps, collect flags and discoveries in a travel journal, and pick the challenge that fits — from beginner to pro. Small typos are forgiven.

GitGround

Markdown workspace with Git inside

Alpha

A native workspace for Mac and iPhone: write Markdown, browse files and attachments, search locally and sync versions — with conflict resolution and file restore built in. Your projects stay ordinary folders; the Git plumbing stays out of sight.

macOS iOS SwiftUI libgit2

Earthfront

Supply & Command strategy game

Playable prototype

Real-time strategy where logistics win wars. Fronts form automatically, supply flows over land and sea through bottlenecks, and holding cities decides the match. World, Europe and East Asia maps, a guided tutorial, Finnish and English.

macOS Browser TypeScript

Portable Project Truth

Project memory for AI agents

In research

A living, auditable project memory that AI assistants can share. It turns meeting notes and project discussion into structured decisions, open questions, risks and changes — so every agent works from the current truth, not a stale transcript.

API AI agents Cross-assistant

How we build

A small studio with an AI-native workflow.

The robots in our tagline are real: AI coding agents are part of how we plan, build, test and document every product. That lets a small team ship native-quality apps across four platforms.

01 · Agents in the loop

Humans decide, agents accelerate

We pair with AI agents for implementation, code review, QA and runbooks. Product decisions, release gates and quality bars stay with people.

02 · Privacy first

Data stays close to its owner

EU hosting, signed data processing agreements, minimised data and local-first storage where it fits — like Ostoslappu, which keeps lists on the phone and in your own iCloud.

03 · Built to last

Native where it matters

SwiftUI on Apple platforms, Expo and React Native for cross-platform products, automated tests and documented releases — software we can maintain for years.

About

An independent studio, operated by a registered Finnish company.

Supaa is the apps brand of Morimoto & Company Oy, an independent software company founded in Helsinki in 2017 by Taro Morimoto. For years the company built web and mobile products for clients as a freelance studio.

Supaa is where we build our own. We are bootstrapped and product-led: we start from a real problem in our own lives or communities — a martial arts club, a family grocery run, kids learning geography — and grow it into a product people rely on.
