the first iPhone relied on the web it didnt have "apps"
it was only after the terrible web pages did they resort to containerised web pages... That game developers abused and we have the situation today...
now with the need to support android + iPhone + iPad + windows + Mac are people finally understanding that Marked up Text is much healthier and CHEAPER
its called a website and there are standards (shocking)
if your spending the peoples money (government depts) create a website that is useable
(if you must create a branded app I understand there are tools for that, they will allow you to package a website)
