Frequently Asked Questions
Direct answers to key technical, security, and engagement questions.
Should we build native (Swift/Kotlin) or cross-platform (Flutter/React Native)?
For 85% of commercial and enterprise applications, cross-platform frameworks like Flutter or React Native deliver indistinguishable native performance while slashing development and maintenance costs in half. Pure native Swift and Kotlin are recommended when your application requires deep hardware-level integration (such as custom Bluetooth peripherals, low-level audio DSP, or complex AR/VR).
How do you handle testing across the thousands of different Android devices?
We utilize automated testing pipelines integrated with cloud device farms (such as AWS Device Farm and Firebase Test Lab) testing our apps against real physical handsets spanning diverse screen ratios, OS versions, and chipsets before any public release.
Who will manage the Apple App Store and Google Play submission process?
Bitneka handles the entire submission process end-to-end. We configure certificates, provisioning profiles, privacy disclosures, store screenshots, age ratings, and coordinate directly with Apple and Google review teams until the app is live in the store.
Can the mobile app share code and backend APIs with our web application?
Yes. By designing clean RESTful or GraphQL APIs with standardized JSON data schemas, your mobile app and web platform share the exact same backend services, authentication mechanisms, and business logic, avoiding duplicate engineering effort.
How do you ensure user data remains secure on lost or stolen mobile devices?
We store all authentication tokens and sensitive credentials inside the device's hardware-backed Secure Enclave / KeyStore. Local databases are encrypted using SQLCipher with AES-256 keys, and sessions automatically expire with biometric re-authentication required.
