<script type="text/ng-template" id="Questionario_Page_tipo-fisico">
<h2 ng-init="form.title = 'tipo-fisico'; state.backPage = 'peso'; state.pageview()"
    class="text-center mt-0 mb-60">Quale tipologia di fisico ti appartiene di più?</h2>
<div class="row text-center" ng-init="form.valid = false">

Answer 1

Shame on me.

I figured out what was the problem, after days of debugging with iOS devices and google searching.

When you load too much assets (images, videos, etc...), safari seems to go in an "out of memory" of assets, I'm now using CSS Sprites for handling all the icons and now it works flawlessly.
