DTMF transceiver

Reads tones more accurately than any other app but you can't do anything with it. Not even copy and paste into phone book.

Worked one time, wouldn't reliably send tones after that.

Again, like another reviewer decoded DTMF fine but can't copy paste to is of limited use :/

Wouldn't even open with the phone app active

Why dont you add support to keys A to D?

Do not update, there are video ads now.

Needs buttons for A, B, C, and D digits. Needs to mute the bleep that Android generates when a button is pressed.

The listened decoded number is too small and difficult to read, but it works! and helped me to solve a little mistery... Usefull.

The decoded text is difficult to see on the background, but it does work. You'll need to provide an external sound source, like another phone for this device to decode the sound.

if I wanted to make dtmf tone, I'd just use my phones keypade, that's about all this app does. I tried to decode a tone,.. nothing. nice ideia if it worked..

Crashes on open. Droid maxx (ultra)

The colour scheme makes the numbers had to see but seems OK to use

Works well, but why activating a vibra-motor? Why not disabled eg in option ?

hard to see the numbers

Crashed constantly

Receiver ok, thanks

Won't consistently decode rapid (~50msec) tone sequences. Clear button is covered by ads, and had to be touched multiple times to clear the display. Needs to override screen sleep mode. Sending seems to work ok.

Would give 5/5 but clear button did not work on my Sam note 3, would like to source code to see how it works

REPAIRS required... does NOT continue to function background after decode,screen lock, or looking at other apps..FORCE STOP, required to make this application work again after sleep?? Please fix thank you.

Receive and transcode DTMF or send DTMF tones.

This the worst software i have ever used...

As a free application this works very smooth.
