FAQ

Frequently Asked Questions

Is this service for mobile apps or website maintenance?

This service is specifically engineered for mobile applications (iOS and Android built with Flutter or React Native). We also offer separate website maintenance services.

Can you maintain an app built by another development team?

Yes! We begin with a code audit to review your app's architecture, dependencies, and code quality before taking over maintenance.

How often should a mobile app be updated?

We recommend monthly dependency checks and quarterly feature/OS compatibility updates, alongside immediate hotfixes for critical security bugs.

Do you handle Apple App Store and Google Play updates?

Yes. We handle building, signing, and releasing updated versions to both the Apple App Store and Google Play Store.

Do you offer emergency hotfix support?

Yes. Our maintenance packages include priority support for critical bugs, server outages, or emergency security patches.
