I did not want a lot of visual noise and this fit the bill. Also larger type since I'm on a Mini 4. Very stable. Here's an odd request. Once you've found the words, you get applause (like I need that) but I'd like to be able to take a minute and just study the screen and look at the shapes before I get the screen message asking to start a new puzzle. I'd also like the option of being to search for words without any cues below. An "on/off" would be a nice option.
Having said that, I'm pleased with the app and I tried out several beforehand. It's relaxing and at the time engaging. Well, maybe that's why it's relaxing.
