It's a great idea if it worked. Would be very useful.
Doesnt work useless app
be careful I would advise to be careful with any apk that customizes ring tones because if they do not work right they can change/override/disable your phone settings... like to zero volume always on answering calls, ringing sounds on phone. Having determined this was the apk that kept defaulting my phone volume, system, microphone settings, to zero, rendering my phone useless and causing me countless headaches, I would not recommend the apk.
* switch back mode after ringing
* select mode to switch to
* improve number matching
* show names
* add numbers from contacts
* add german translation
