every time we have the chance to reproduce your business logic in easy steps, we suggest hybride Apps, but there are facts to use native technology, e.g. Smart Watches, Special Phones with explicit OS Versions, the use of early beta functions or faster Apps, it is better to implement native, 

We use newest XCode IDE with SWIFT or Objective-C native and all SDKs for all Apple devices,

 Another way that we take for fast and native Cross-Plattform-Devlopment is the use of Microsofts XAMARIN ™ Add-in. It builds the App for 3 Smart Phone operating systems: Android, IOS and WINDOWS with one and reusable .net Code Base.
