New additions?

Could you please add personality, adjustable search depth, and more evaluation lines (10)! This app is literally the best out there but these are all features I have desperately wanted in one app but haven’t been able to find in an all in one package. Thank you for all your hard work! This app already is the best, but these features would blow the competition out of the water.

Opponent always runs out of time.

No matter what I do in the options, I always win because my opponent runs out of time. The game continues, however, even though the clock is 0.00 so that’s a good thing. This issue starts immediately: playing white pieces, I play 1. d4, black always immediately plays either d5 or f6; I play 2. c4 . . . . black “thinks” 20-40 seconds before making a second move, usually c5. Really? As long as 40 seconds to make the second move. And that “thinking” exists throughout the game. For instance, black offers a queen trade: I accept. Then black deliberates 20, 30, etc. seconds whether or not to capture my queen when there is obvious nothing to deliberate. Hardly a realistic or enjoyable scenario.

Crashes often

Running on an iPhone 11 using iOS 14.4 and it crashes almost every time I use it. Crashes when I manually set up a board to play out or when I'm adjusting settings.

I love this app and would love it to work seamlessly. The crashing is unfortunate so I can do anything to reduce the crashing, let me know.

Love the board setup option, option to play as black or white, the two or three move recommendations. I would love if it told you the opening you were playing as you chose the moves.
