Simple but fun

I like not having pencil marks and being able to just use my brain. It makes for a different experience. But quite a few of the puzzles have incorrect solutions. 1>3 and all sorts… I can’t get the app support link to work so I’m just writing here so Andrew can see there’s a problem.

Missing very basic features

I’ve been looking for my ideal version of a Futoshiki app, and this is by far the worst one I’ve tried. No pencil feature at all, and the method of filling in the squares is ridiculous (tap multiple times to shuffle sequentially through each option)
