Mobile app development with React Native
iOS and Android apps from one React Native codebase, built by a senior Toronto studio. Recent work: the JOL learning app and a Gen Z finance app.
We design and build mobile apps for iOS and Android from a single React Native codebase. The same team owns the app, the API behind it and the release process, so product decisions do not get lost between vendors.
Our mobile work includes the learner app for JOL, a game-based corporate learning platform from NUTS Inc. in Tokyo, and a gamified personal-finance app for Gen Z users, where our founder served as CTO.
Mobile app development
What we build
Cross-platform apps
iOS and Android from one React Native and Expo codebase, with native modules only where a feature needs them.
Backend and APIs
NestJS and GraphQL services, authentication, notifications and the admin tools the app depends on.
AI features in the app
Features such as JOL’s AI-driven weak-spot practice, built on OpenAI and tested before release.
Multilingual interfaces
Localization planned from the start. The JOL app supports more than seven languages for foreign employees in Japan.
Store release and updates
App Store and Google Play submission, followed by post-launch fixes and feature updates.
How we run these projects
- Start with the smallest version that proves the core loop, then expand.
- Test builds on real devices, reviewed together in a weekly meeting.
- A senior engineer stays on the work from architecture to release.

JOL
A game-based corporate learning platform from NUTS Inc. (Tokyo). We built the learner mobile app for iOS and Android — gamified quests, AI-driven weak-spot practice, and a multilingual UI for foreign employees preparing for the JLPT.
FinTech · CTO
Gen Z personal finance app
As CTO, built a gamified personal-finance mobile app for a Gen Z audience, owning architecture and the engineering roadmap end to end. (Product under NDA.)
Frequently asked questions
Do you build for iOS and Android at the same time?
Yes. We use React Native with Expo, so one codebase ships to both stores. Platform-specific code is added only where a feature needs it.
How long does a mobile app take?
It depends on scope. A full-featured application typically takes two to four months. We give a detailed timeline after the first consultation.
Do you support the app after launch?
Yes. We offer support packages covering bug fixes, security updates, feature work and store updates.
