Hello,
Would you please provide me the full Project Requirements or Wireframes so that I can get your idea fully and can be able to revise my budget finally?
For your concern, we have developed 250+ apps for Android, iOS, BB, Windows Phone and PhoneGap so far. I'm very much confident enough to develop your such app.
I'd like to chat with you in details. Please let me know your convenient time.
Looking forward to hearing you soon.
Thanks.
