In depth

How we approach Flutter

Why teams choose Flutter

Flutter's rendering engine gives identical, highly custom interfaces on every device, with fast development thanks to hot reload. It is a strong choice for consumer apps where design and animation matter.

Clean architecture

We structure apps with clear state management and separated layers, so features are easy to add and test as the product grows.

Quality on real devices

Automated tests, testing across popular devices and crash reporting keep the app stable as you release updates.

Launch and beyond

We handle store listings, review guidelines and release pipelines, then keep shipping improvements with the same team.

Working with us from Japan

Time-zone overlap

Japan is three and a half hours ahead of India, so our working days overlap for most of your afternoon, with a stand-up and same-day replies.

Japan's Act on the Protection of Personal Information (APPI)

We design to the APPI: clear purpose of use, security controls, rules for third-party and cross-border transfers, and data hosted in Japanese cloud regions when required. We sign NDAs before work starts.

Billing

Invoices in Japanese yen (JPY) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
