I just wanted to let you guys know that the pieces are blurry on the iPhone 4. If you open an app like Stockfish and use the same piece set (I like Alpha), you should easily see the difference and how crisp the pieces look in that app. I figured this would be an easy thing to fix in an upcoming release. (I couldn't find the proper forum for this--sorry if it's in the wrong place.)

what?? which pieces are blurry? mine look great!

They all do; I tried switching to different sets of pieces. It looks like you upscaled the images from the low-res version, or maybe they're saved as jpegs... I don't know, but the edges of the pieces just look fuzzy. Download Stockfish (free) and switch between them.

Here is a comparison picture I made:

The pics weren't compressed at any point. PNG screenshots from my phone -> cropping on the computer -> PNG screenshot of the two together. I think this proves pretty clearly that I'm not imagining anything. 

I have both apps on my iPhone 4 and I can't tell the diff. But after 5 minutes of looking at both apps and your pics, everything is blurry to me now! Time to visit the eye doctor ;)

noted. i just generated new pieces for the next update. hopefully in the next few weeks!
