Hello,
We've developed 10+ apps on Radio and Streaming apps for Android, iOS and BB. In your reply of this message I'll share you all the links of them so that you can get a clear idea of our skills.
I have some queries about the voice record portion. Please let me know your convenient time so that we can discuss more.
For your concern, we have developed 250+ apps for Android, iOS, BB, Windows Phone and PhoneGap so far. I'm confident enough to build your such app and ready to start.
Looking forward to hearing you soon.
Thanks.
