Mobile app development company for iOS and Android
Devello is a mobile app development company based in Istanbul. We design, build and launch iOS and Android apps as one team, from the first screen to the App Store and Google Play. Fixed-scope plans start at $4,999 and run from 3 weeks to 12 weeks.
What our app development agency delivers
iOS and Android from one team
Custom iOS and Android development with a native feel. Cross-platform builds use React Native or Flutter, so both stores ship from one codebase.
Product design included
User-centric UI/UX design is part of every plan, from basic screens on Lite to a fully custom design from Basic upward.
Backend and integrations
Backend, API integration, push notifications, analytics and an admin dashboard, depending on the plan you choose.
Store launch
We prepare the release for the App Store and Google Play and optimize the listing, so launch is part of the work and not an extra.
Mobile app development cost
Every plan covers design, development, testing and deployment. Payments follow delivery milestones, so you pay as we ship.
