Any specific APPs out there we should all know about? Doesn't have to be iPhone; listed below are the one's I've got and I suggest fellow iPhone users, take a peek.

• Asmart Hud+ :: this cheap APP gives you a Heads Up Display showing current speed, live compass, speed warnings - just place the iPhone on your dash facing upwards (I have a rubber case and the phone sticks just fine) - you can even colour code the HUD to match (green)
• BMW M Power Meter :: branded BMW M', you can measure G force and time runs too (free)
• CoPilot :: the cheapset 'proper' satnav I've used on iPhone (not sure if USA has it)
• Dynolicious :: a Dynamometer APP

I've also gone as far as creating a shortcut to this forum (see screenshot) - any others we should know about? Anyone have the TomTom satnav?
