All element larger on simulator

I developed my App and it’s working fine, then suddenly when I try to run on iPhone 6, all the elements get larger: icon tabs, font size, input size, as I it’s running on iPhone 5, for example.
It only gets fine again if I start a new project and copy the www folder inside.
My plan is to submit the same App several times to AppStore changing only the name and the icon, so I clone everything with git, open it on Xcode, change the icon and name and it happens again.
Please help me. It seems I am the first with this problem, because there’s nothing like that on forums.
Thank you.

I am having the same problem. Did you resolve it?

Sounds like a viewport problem.

Check your index.html…
