Tax Code and Regs - TouchTax - Android Apps on Google Play. I can think of few things less pleasant than reading the Tax Code. However, lawyers must have a passing familiarity with its terms on occasion; and, this little $2 app puts the entire code at your fingertips. It contains the entire Code and the Code of Federal Regulations in a readable format. However, I would not mention to a date that you carry the entire Revenue Code on your phone. You are really already plenty dorky enough.
