Problem with masked domain redirect and web app rendering

Hi I have just published a web app thunkablecompanion
which works fine - but when I access it (on an iPhone) via a domain redirect -masked (
it renders the app about 25% smaller on the screen - so the user will need to zoom ;-(
any ideas how to get it to fill the screen?

solved it - Im using Namecheap and with masked domains I cant edit the meta page so unable to add viewport info - have to use unmasked redirect
