Just today I used this app to try to understand my air con remote which is written in Chinese characters. So between Google Translate, a great website where someone tried to translate the remote, and Skitch, I figured out some of the controls. Trouble is, the AC is still not cooling. Here is what I did. I took a picture of the remote, and then used Skitch to write in the English translation. I printed the picture with the annotations from Skitch to leave beside my remote. This should help me, especially once the AC is working!
