Ipad app sound level meters vs a portable sound level meters


Would it be a good idea to buy a separate portable sound meter or does an iPad app do just as good?

There's also a lot of cool frequency Apps

From the bit of investigation I’ve done the Apple stuff does a pretty descent job on its own. If you’re looking for that natts Ass accuracy I would say buy a meter. 

I find decibel app on iPhone works well to help get a handle on the sound in one’s room.

You might want to get a calibrated mic. rather than rely on the built-in mike. I found the ipad very useful to set up EQ for my car system.
