Compare to Other Call Recorders
=====================
On the market several other call recorders said they can record VoIP calls but actually they can't (you can test and confirm this fact yourself). Why? Because Android allows only one app to use the microphone. As a result
* When a VoIP call is ongoing (so the microphone is being occupied) the recorder can't record the call because it is blocked to use the microphone.
* If first you start recording to let the recorder occupying the microphone second make a VoIP call to your friend you'll find your friend can't hear your voice because the VoIP app is blocked to use the microphone.
However this app uses the microphone in a shared manner so it works perfectly with all VoIP apps on the market.


Compare to Other Screen Recorders
=====================
This app also works as a screen recorder and it is more powerful than other screen recorders.
* All other screen recorders can't record VoIP calls because Android allows only one app to use the microphone just as said above. This app can record VoIP calls perfectly.
* Most other screen recorders can only make external recordings audio saved is bad because it is mixed with environmental noises. This app copies sound data directly from the system internal (internal recording) audio saved is perfect.
* Some other screen recorders can make internal recordings but they only work on a part of phones and they can't record audio from many apps like music streaming apps and video streaming apps etc. If you use this app to make screen recordings you can record audio on all phones from all apps.


Start / Stop / Pause / Resume Recording
=====================
When a VoIP call comes the VoIP app (WhatsApp Skype etc) doesn't notify this app so this app can't start recording automatically because it doesn't know the event. You should tap the record button on the notification or on the float view to start recording. When the call is ended this app doesn't know the event either so you should tap the stop button to stop recording. During recording you can pause and resume recording if you want.
