None of those are made for mobile/table. Not a single one.

Neither is this. Page says it works on all platforms but when I try the code editor on my Windows Phone 8, it's clear that it does not. Page scrolls to weird locations when I just type. I typed Hello and some second later text was scrolled out of visibility. Spent a few minutes just trying to type, but it really does not work. (This was typed on same phone without weird scrolling...)

Duh - when people say something is mobile/tablet compatible, obviously what they mean is compatible with the latest version of Android or iOS.

Maybe he wanted to keep his code hack-free.

Who is crazy enough to code on a mobile/tablet though??

Why? With a bluetooth keyboard, it's not that unpleasant to write a few lines.

Actually we are selves were surprised at the number of people that use it on iPad.

I suppose Codio has iPad support it looks like.

well technically any browser-based editor is going to be multi-platform. i'm just being picky.

I think they mean because they have an iphone/ipad/android and other platforms supported. Not just browser.
