Review from A Google User
GCF test case tool Bin von dieser App begeistert,benutze es beruflich und es erleichtert mir das Testen ungemein!
The only app with good steady tone generator . other apps have choppy dtmf on my s4 . You can adjust tone lenght and pause. the dtmf decoder is not right thouht. I can trigger dtmf with wistle
Worked After others failed, this one worked.
Actually works Out of all the dtmf decoder apps I've tried, this one actually works.
Great App + IT WORKS.
Very handy to have in your toolbox This is a very useful app to have in your phone.
Great app, smart and easy to use with more than 90% accurate
