flawed

It seemed to work well in the past. Today I noticed it couldnt calculate a tip correctly on my iPhone 5. As a test, my wife brought up her version on her iPhone 4 which hasnt updated its operating system. Check Please determined that a 10% tip on $10.00 was $0.87. The same thing my verison determined.
