Hello, I am a programmer that is just starting, and am trying to get some of my programs out there, and even trying to sell some. My first real program that I made by myself was a simple countdown timer that beeped when time was up, hence the name 'mytimer'. I hope that my software does you good. I think it's fair to mention that my favorite phrase is "There's an app for that."  If you'd like a TI-84 version of any of the math programs, there's apps for those, too. Just let me know through the contact page.
