"My fishing advisor" is a good one if you're into fishing and wanna know what's biting (kinda worked for me, but seemed totally logical). "Torque" is another good one to use with your car or truck if you're into figuring out your mpg, horsepower, torque, 0-60 times, diagnostic info, etc... You must buy a blue tooth adapter to connect to your obd2 connector in your 96' up vehicle though. Can read and clear codes too...basis hp and torque off of g-force, gps, and engine data (may not be totally accurate, but is fun to play with).
