Works great on my S7! I'm also reading reviews and I have to laugh. Right on the app it says this isn't a professional device it uses a cell phone microphone that most phones will only pick up 90 to 100db's. So if your system in your car hits 138.9 and the mic in your phone is limited to around 100db's then guess what? Your not going to get a 138.9. There's nothing wrong with the app there's something wrong with you! Read instructions before you give something a 1 star review. By the way if you spend more than $20 on a POS old model cell phone the app might just work a little better.
Rating status does not record , Continually requests rating. Of course ads pop-up, dats why it's free fools! Nice large graphics for a music class.
This app is awesome tells you what range it is was about ready to get hot on this company until I use a different microphone use a Bluetooth mic high quality works better than your phone no matter what phone you have all phones have a crappy stock mic no matter the brand
Pretty good app for free. Ads are a little annoying, but it's free. Like the ability to calibrate it to improve it's accuracy.
Biggest kak ever my sound push out 138.9 and this meter says only 104.1
Use it with my mixer desk ,easy read at a glance to monitor sound mix levels.
