I use Decibal 10th because it's free...
I use the audio suite from Studio Six Digital
The JL Audio free SPL app is way off .....
Check out Faber Acoustical on the app-store if you want a precision tool.
but they are also tres cher

Maybe you have LOUD suits.You Bet! I have the "upgraded" version of the JL apps and it is also a total piece of crap. IT'S A TOY, doesn't work worth a damn.
I can go into the quietest closet in my house, hold the iPhone between a rack full of suits and sport jackets, turn off the main circuit breakers in the house, hold my breath and it still registers 40-50 dB. What a waste. I should get my money back.
There is no way any of those apps can even be imagined to replace a real measuring device of any kind.

The Faber app's work on the iPad and iPhone. The iPad is used as an instrument emulator for a variety of critical fields. Both iPhone and iPad have computers onboard, and can process properly.
