Hello sir,
We are working on android platform from last two years. We went through your requirement. As you need n android app to record voice call, we'd like to develop the same for you.
We are new to freelancing and we are looking for the projects to support our profile. Can we discuss the same regarding your project so that it will give us a more clear idea. We would love to put our efforts for your project. :)
Awaiting for your reply.
Thanks and Regards
