What is cross-platform app development?
Cross-platform app development means building one codebase that runs as a native app on both iPhone and Android. Modern frameworks make these apps feel native while cutting build and maintenance cost, because every feature and fix is written once instead of twice.

How much does a mobile app cost?
Our mobile apps start from $12,000 for iOS and Android together. Price depends on screens, integrations, offline needs and the backend required. If you already have a web app with us, the mobile app can share its backend, which lowers the cost.

Mobile App Development questions, answered
Do you build native or cross-platform apps?
We usually build cross-platform, so one codebase serves both iOS and Android, and recommend fully native only when an app needs it.
Do you handle App Store and Google Play submission?
Yes. We prepare the listings, privacy details and builds, and handle the review process.
Can you add a mobile app to our existing web platform?
Yes. The app can use your existing backend and user accounts.
Who owns the app?
You do. The source code and the store accounts are yours.
