Cross-platform apps are primarily developed in HTML, CSS and Javascript (the programming languages used to build websites) and then compiled into the native code required by Apple and Android apps. We say 'primarily' because some functionality still needs to be built in the core native language in order for it to work properly. Native apps are built directly in Swift or Objective C for Apple, and Java for Android apps.

Generally speaking native built apps will perform better than cross-platform provide a more standard look and feel for the particular platform, and provide credibility for practicality that demands deeper interaction with device hardware.

However, it is important to assess each app on a case by case basis, as building once for both platforms is more cost effective. Newer programming languages such as ReactNative are providing additional opportunities to reduce the cost of development and maintenance.

Yes, we can do it for you if you want us to maintain the app as per our contract. However, we believe that to start with a minimum feasible product for startups and then update the app in future with more advanced features usually when the competition is going up.
