I like the look of the desktop version of the website. Very clean. However I primarily use this website on my Samsung S3 while on the train. The design looks clean on the mobile however its usability is pretty low. Below are some problems I found while using it on my mobile.
Why is the search functionality hidden on a mobile device? I find that very annoying because I prefer to search for a Pokemon then find out where to catch it / evolve etc from there.
On the location pages (i.e Unova Route 6) when you scroll down to what can be caught in the location, the list does not fit on the screen horizontally. As a result each of the lists (walking, surfing, super rod) gets its own internal window which can then be scrolled left or right. This causes problems when trying to scroll through the page. If your finger lands on one of these lists it stops the scrolling and makes it difficult to move further down the page. Turning the device horizontally does not fix this problem as it just zooms the list in further. This also applies for the advertisements they seem to be squashed into a smaller line and have their own scrolling windows also.
Another issue that was reported above was the rarity pie charts are not visible on either desktop or mobile versions. (Maybe having a text % would be better?)
Since the search function is missing on the mobile version I attempted to go to Pokemon Data > Pokedex > All Pokemon master list. I found it nearly impossible to press and activate the "Name" text entry field to bring up my keyboard to search. The hit box for that text entry needs to be larger somehow. The functionality works fine on the desktop version and suits a solid connection to the internet. Yet on a mobile device and especially on the train where mobile connection can sometimes be patchy the searching is very laggy and sometimes results in a "Unable to find webpage" error message showing up where the refined list should be.
Lastly when opening this wall/comments section on a mobile device it appears the grey stripped right side bar (that can be easily seen on the desktop version) appears to break into the white area and over the top of some of the text. This makes reading some comments and posts really hard (black text on grey background is really annoying).
Hope all that feedback helps improve the mobile version of this website. In the meantime can you add in some way to switch to the full site from the mobile browser? Most sites do this in case the mobile site is lacking for some users.
