Mobile App FAQs

Common questions on platform choice, publishing, and device support.

Should we build Flutter or Native (Swift/Kotlin)?

For 90% of business and consumer applications, Flutter is our recommended approach because it yields near-native performance while slashing development and ongoing maintenance costs by up to 40% across both platforms. For apps requiring deep OS-level low-latency hardware interaction (e.g. custom audio DSP or low-level Bluetooth), we build native Swift or Kotlin modules.

Do you handle App Store and Play Store approvals?

Yes. We manage the entire store submission process including developer account configuration, screenshot formatting, privacy manifest declarations, and addressing review guidelines directly with Apple and Google reviewers.
