FLUTTER APP DEVELOPMENT
Flutter app development company
Devello is a Flutter app development company based in Istanbul. We use Flutter to ship iOS and Android apps from a single codebase, with design, backend and store launch handled by the same team. Mobile plans start at $4,999; apps on both platforms start with Mobile Basic ($8,999, 6 weeks).
What Flutter app development with Devello includes
One codebase, two stores
A single Flutter codebase ships to both the App Store and Google Play, which keeps features and fixes in step on iOS and Android.
Custom UI that looks the same everywhere
Flutter draws its own interface, so a custom design renders consistently across devices and OS versions.
Backend and integrations
Backend and API integration, push notifications and analytics, with Node.js, Firebase and PostgreSQL behind the app.
Store launch
We prepare the release for both stores and optimize the listings as part of the project.
