I've create aweber forms for my website: http://www.singaporeofficespaces.com
The forms looks great in desktop version, but having problem displaying properly in mobile version.
So I'm wondering if switching to gravity form can fix it?
Gravity Forms is mostly responsive, but it is partly dependant on the theme, so I can't say we would be able to completely help with your resizing issue, but it might work better. Check out our demos at http://gravityforms.com/demo and try resizing them on your desktop to see what they look like at "cell phone sized" resolutions.
