[2013-07-23] A Google User: This app reads phone calls and identifies your state and your identity. Why? |
|
[2013-06-18] A Google User: Not installing I had this on a prior phone but not reinstalling because of invasive permissions. You don't need my phone identity to display trig data. |

[2012-11-28] A Google User: Bionic usa I like but on high res device you need magnifying glass |
|
[2012-08-20] A Google User: This should help This should help for college. But the menu needs upgraded. I click 'other', and it freezes. But I'll like it. |

[2011-01-16] A Google User: When you set the angle the wrong angle is shown. Eg. 90 ° is shown as 270° |
|
[2010-12-04] A Google User: Value of (0,-1) is located at top of circle? Kind of a major error |
|
[2010-12-04] Marten: Value of (0,-1) is located at top of circle? Kind of a major error |

[2010-12-02] A Google User: Um... counter-clockwise produces a positive θ/degree growth. You have it backwards. You may want to fix that huge error... |
