Okay, but not worth the effort – EMF Meter Free Utility for iPod, iPhone Review

The app functions well, but that doesn't make up for everything that is wrong with it. It is constantly asking you to let it use your map location (why?), upgrade to pro, or leave a 5 star rating on the App Store, even if you've already left a rating. Other than that, the app crashes every third time you try and start it, and it only runs for a little over a minute before it crashes anyway. The meter function works, but it isn't worth the miles of red tape you have to cut through just to get a good reading. I am so glad I didn't pay for this. If I did, I would be very, very upset.
