Depending on what your trying to monitor and vehicle You can run some more basic programs like the torque Pro app using a bluetooth OBD adapter. What you can view depends on your stock truck's sensors etc. at about $30 for app and adapter its kinda a no brainer, but if its not covering all your sensors you want you may end up in a fullscale tuner/gauge and quite a bit more investment
Torque pro and the amazon adapter is that exact thing and capability, maybe slightly less formatted (but very customizable) but 1/5th the cost.
