I put together www.chessrapid.com for my own use. It's a version of Puzzle Rush / Puzzle Storm that has the added benefit of: 1) filtering by tactical themes and 2) seeing what themes you are frequently slow on / incorrect on. This way I can narrow in on the tactical themes that I need to improve pattern recognition on (e.g. I can take a break from Mate in 1 and Mate in 2; I really need to work on middle game).
