Frequently Asked Questions

Yes. Modern no-code and low-code platforms allow us to build fully functional mobile apps for iOS and Android without traditional programming. The result is a native-feeling app that can be published to the App Store and Google Play.

We build cross-platform apps that work on both iOS and Android from a single codebase. We also offer native iOS-only or Android-only development when performance requirements demand it.

Mobile app costs depend on complexity. A simple app starts around $5,000, while feature-rich apps with backend integrations range from $15,000 to $50,000+. Every Plinthio proposal includes 3 pricing tiers so you can choose your scope.

A simple app can be built in 4 to 6 weeks. More complex apps with custom features, integrations, and backend systems typically take 8 to 16 weeks. We provide a phase-by-phase timeline in every proposal.

Absolutely. We build apps with maintainability in mind and provide a content management dashboard. You can push updates, manage users, and update content without needing a developer.
