United StatesDTMF decodes and encodes DTMF (Dual-tone multi-frequency) tones trough the phones speaker and microphone.
Encoder: Always 2 tones are assigned to each key.The length of the tone and the pause between the tones can be set from 35ms to 1500ms.
A total of 36 marco’s can be used to play phone numbers, ham radio auto patch numbers, amateur radio echolink id's any many more.The 36 macro's can be saved to the phones/tablets memory. This way a unlimited amount of macros can be used. The DTMF tone length and the pause between the tones can be adjusted.
Decoder: The decoder detects the DTMF tones and prints them on the screen. A sophisticated algorithm detects the tones even in noisy environments.

Works great, but needs a microphone level adjustment tool in the 'Settings', because any little sound will trigger a response in 'Receive' mode.
This App is 5 STAR AWESOME! Picked this up for an electronics project that my grandson is doing for school & he absolutely loves this ...Thanks!
This app is super helpful when I need to know what digits a push button box is dialing. I needed to troubleshoot emergency call boxes and this helped me to find out the number they were calling. What is needed, is a "start & stop" feature for the receiving mode. The problem is that after the digits have been decoded, the app continues to listen to everything around and enters additional information.
Too sensitive. No way to turn down mic sensitivity. Randomly stops decoding tones. I need to close the app, then re-open it. It happens when I have been waiting for a tone. Then I need to re-boot, then the tone I have been waiting for is gone.
Love this app it even has ABCD adult many people even know what that is but props to the author
