My question would be 'Why do you need the mobile apps?'. In my opinion, UNA is great at being responsive to PC/Laptop and Mobile devices. There is discussion regarding Apple and Android apps but from my experience, It isn't worth the hassle of trying to get your app approved, especially by Apple. 

Think of it like this.. If your users can got to your website using the PC/Laptop or Mobile devices and use all of the functionality of your website... Why would you make them try to download an external app that does not have all of the features your website has to offer? Most mobile apps exclude certain functions available via Web. 

For me, once the 'Responsive Templates' came out, I never again thought I needed a mobile app. Apple is the most frustrating of all when it comes to 'satisfying' their rules. You can expect your app to be rejected multiple times.. So if you still feel a need to created mobile apps for site, get ready for a lot of headaches.  Again, this is just my opinion
