Tried every imaginable setting, rebooted phone multiple times (iPhone 10) and nothing would get this app to work.

Piece of crap doesn’t work

Plymouth Ma on

Don’t buy! I had a cleanse load send signal and it would not pick up tones. These filthy trash con artists stole my .99. Don’t you fall for it

Works great!

We played around with it, and it picked up the tones and got them correct.

I have to revise my review

When I first downloaded this app it didn’t work at all but after rebooting my iPhone 7 Plus it works GREAT! I actually used it at work today to grab the digits of an auto-dialer that dials very fast and it got it right every time. This thing works almost as well as a real digit grabber. I give it 5 stars now.

Doesn’t work at all

United States

Used a clear and loud dtmf source and didn’t detect anything. I’d like my money back

Great app for professionals in the telecom industry

Cryptonoid on

United States

I use this app regularly when troubleshooting autodialers and telephone entry systems. It saved me so much time. You must adjust noise levels in order to detect dtmf tones in noisy environments.

Pretty useless

United States

Doesn't identify numbers quickly enough. If you want to see what number a call box is calling, for example, it misses about half of the numbers.
