Karaoke Record and Singing App With Bluethooth Mic Android & iOS

The client has 30000 Karoake tracks which we wish to put in a new app (the existing app which is old and lacks features). The songs will be in MPEG4 files (similar to meragana. User will download app, register and key in the registration code. He will then connect with Bluetooth with the Karoake app and sing the song. The app will have controls and features similar to meragana. pitch, echo , volume, tempo Scale Live display of notes Recording Social media sharing etc). User can buy the mic of the client and connect his handset through bluetooth with the app and use the same. Customer will register and use the coupon provided with the microphone. On expiry of the coupon the user will pay and renew for given time period. Payment can be through telco billing or through credit / debit cards. (we will provide telco API and payment gateway API). Unregistered User can also sample 30 sec songs without registering. There will be a report and analytics front end for admin login providing all necessary details. (we can build this part and need the data on a URL..) User will have smooth UI.
