For me, it's no matter what to use - web version on computer or mobile version. Btw, will the web version also available from mobile phone?
You know, it is always inconvenient to use web version on smartphone - anyway, it is better to keep your eyes away from small text, small buttons, small pictures. It will be strange to be in need of ophthalmologist just because you tried to contact your therapist

Hah, yeah, although it can be 'friendly' enough to have big enough buttons, big letters, so there will be no reasons to look for oculist
