This one displays at full size similar to a "sidebar" on Firefox for Android. 10 to 40 characters long, all the basics, no history, just copy to clipboard or generate.

All of the other password generators generate a plain white website with text that is impossibly small to read. You have to pinch zoom to blow up the font size and see what generated password you even got.
There's at least five other password generators that do this, probably eight by the time I finish going through the list.
