How to know which themes are responsive?

I tried using your Sunset theme for my form. Unfortunately after building it I learned that both the styling and functionality do not perform well on some mobile devices. Specifically iPads.  Do you have some fully responsive themes or templates? And where can I find those?

You may try to search with 'mobile' and 'responsive' keywords to get a list of the mobile optimized themes.

Although, this is not guaranteed that applied theme will be fully compatible with all the mobile devices since each form and case is different. If you need any further assistance on this, please let us know.

Thanks Mike. If I have a theme, and I'm not sure which category it was in, how can I see from looking at it or it's description if it is response. (I'm only interested in responsive. - not just mobile.) 

If you see a 'mobile' or 'responsive' tag in theme description it usually means that mentioned theme is tested/optimized to work properly on both desktop and mobile devices.

Please note that you are not required to apply a theme. This is also possible to use a standard theme and/or form designer styled form. Such forms should be mobile friendly by default.

Thank you.

I think I might try just starting from scratch. This new "responsive" theme is just skinny all the time. It looks unnaturally narrow on anything other than a phone. Thanks for the tip on how to check.

Are there any themes that are truly responsive? And don't just look skinny all the time but actually resize to fit the device they are on?

In general, all the themes are supposed to be mobile friendly. For example, standard theme adapts its size based on a screen width, and this should be similar with other themes.

We do not have a list of some specially responsive forms.
