Alright so here's my question. What apps and or computer programs do you use, what's it for, and is it for your phone if so droid or apple, or pc and if so is it windows, linyx, or apple? And cost if any?

I use Car Trak4 for my maintaince log on a windows 8 laptop. and the Torque Pro app on my LG Lucid Android based phone. Car Trak4 was free through download.com. and ya'll know the price of Torque Pro already.
