How accurate are they?
Specifically the JL Audio app's SPL meter and RTA
And the various tone generators for setting gains.
Are they close enough to get you in the ballpark or a waste of time ?

There are correction filters built in to account for the adjusted frequency response as heard from the iPhone mic. Should be enough to get in the ballpark

They are only as accurate as the iPhone's mic and speaker
Hence the reason for the questions...I imagine the mic's on high dollar equipment are substantially better.

Unfortunately iPhone, tuning and app are such common terms here the search pulled up everything BUT what I was looking for.

Expensive, but from the looks of it you get a high quality digital ipod dock with balanced outputs and toslink digital output. Also has a regulated DC input that will work straight off the cars electrical without the need for an external high quality PS (fuse needed of course). That right there is a $200+ value.

The spl meter is only good to like 90db, so yeah; however, the RTA is not bad for quick tune. I use it on initial fire and before break in on installs that have an external EQ or processor. For what it is, and what you pay, it works great. With a 3 dollar external mic, it only gets better. I plan on picking up the new audiotools interface for my iPad2.

Hell I can raise my voice and shoot the SPL meter over 100.
