One voice control app I would love to find

[kroewe]

Between Voice Command and TellMe...most of my voice control needs are totally met. I know that a lot of people dont like the voice command programs and try to get rid of them, but i am a landscaper and work outside and my hands are dirty most of the time and all the voice control i can get helps me out during my day.
What i have searched far and wide for with no success, and what would be a true phone saver for me, is a voice control calculator.
if i could open my calculator with voice command, then be able to dictate add., subtract, mult, and divide problems and get a voice answer, it would save me a lot in screen protectors.
Maybe its something someone would like to take on as a challenge...
