the problem with apps and databases such as this is the accuracy and currency of the data. not saying they're not worth using just suggesting that one not put blind faith into such a database. we've all heard the stories about some folks getting lost or worse after abandoning their common sense and blindly following their GPS units. don't do the same thing with a single low clearance app or database.
be sure you know the source of the information used by the app. I've always trusted...to a large degree anyway...the low clearance data in the printed Rand McNally Motor Carrier Road Atlas. that atlas has an excellent track record for accuracy. but even that fine publication can have errors.
btw...only two apps for the iPhone come up in iTunes after searching on 'Low Clearance' and neither is free. one costs $0.99 (nearly free) but the other is $3.99.
