DTMF Decoder - Reviews, Revenue and Downloads - Apple App Store

Description

Turns your iPhone into a simple DTMF decoder. Simply hold the iPhone's microphone near to a clear source of DTMF tones (telephone "Touch Tones") and it will display the numbers being dialed. The decoded digits are also placed into a text area from which you can copy them to the clipboard.

DOES NOT WORK DON’T BUY

iPHone 13. iOS 17.4.1 Never displays anything

This app doesn’t work

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

Piece of crap doesn’t work

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!

I needed used this to diagnose an issue with a call box for an apartment building. It worked great!

Update

Any way to get this work with new iPhone update??? Great app but now it won’t work....

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

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

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

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.
