DTMF Decoder

By dreadtech.com

This app is only available on the App Store for iOS devices.

Description

Completely redesigned decoder!

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.

A row of LEDs indicate which frequencies are present in the signal - each LED corresponds to a single frequency.

Customer Reviews

Poor performance

Only usable on an iPhone 6S Plus at full sensitivity, and works poorly then.
