Hey atatimber, How are you?
Its always good to work on something if we have an already existing version of it.
If we are doing this, I myself will work on iOS (Apple) app updates and my colleague will work on android application.
Since the iOS app is already available I am sure the webservice features (if any) is already up, still if you need any updates on that, I can help you with it.
Please ping me here or prefereably at skype. (skypeID: deepakkarumathil)
Thanks,
Deepak
