About Proof of Quilt
The puzzle Proof of Quilt is one of many pencil-and-paper puzzles.
An instance of Proof of Quilt consists of an m × n rectangular board of unit squares. Each square is either white or black, and some black squares contain a number. A candidate solution to the puzzle consists of filling
in some of the white squares with a black half-square (isosceles right triangle filling half the area); white squares may also be left entirely white. Each number in a black square specifies the number of b/w squares that should be among four (vertically or horizontally adjacent) neighbors of the black square. (A black square without a number allows any number of b/w neighbors.) The objective of the puzzle is to fill the white squares in the given board while satisfying the above constraints and so that the remaining white area consists only of (empty) squares and rectangles.

Really nice. Just one item for the wishlist: when I'm doing these on paper I like to put a dot to denote a definite blank. It would be nice to be able to do that here too.

This is a decent implementation of the new Shakashaka puzzle from Nikoli, with good puzzle aesthetics. It would benefit from a more intuitive marking interface, as well as the ability to distinguish "known blank" from "unlabeled". Also, there is a crashing bug in moving from puzzle 45 to 46 (perhaps because the latter happens to have a smaller board size?).

The puzzles are a tad buggy. I have had some comeplete without being fully solved, I had one puzzle crash near completion a few times, and I'm not sure puzzle 99 is actually solvable. But overall this is a good puzzle app.
