Cross-Platform & Native Capabilities

Hybrid Mobile Applications

Hybrid apps use web technologies—HTML5, JavaScript, and CSS—wrapped in native containers to deliver cross-platform functionality with reduced overhead. This approach can be ideal for simple apps or MVPs.

Native iOS and Android Development

When performance, responsiveness, or platform-specific features are critical, we build fully native apps using Swift (for iOS) and Kotlin or Java (for Android). These apps align perfectly with platform guidelines and can take advantage of all native capabilities.

Frequent Mobile Approaches

Technologies are always changing and Keyhole keeps up on the latest approaches in mobile development. Often, Flutter or .NET Maui are the right choice for mobile development initiatives when a cross-platform mobile approach is warranted.

However, as a technology-agnostic firm, Keyhole works with several other mobile development framework options.


React Native is another excellent mobile choice.
