Hello,
We are IT-Engineers with higher educations, having more than 14 years of experience, developing mobile applications using Apple native iOS SDK.
Recently we have launched a WhatsApp-similar iPhone application which has been successfully submitted to the iTunes AppStore by our client. Due to the signed NDA we are not allowed to disclose more details, however all the experience gathered in this project remains at our disposal.
The accompanying bid and the time estimation are tentative, as the provided description has revealed us mainly the general aspects of your requirements.
All the additional information about the project would allow to estimate the budget frames and the completion deadlines reliably.
Life-time Bug-free warranty is a part of our standard service.
We would be glad to answer your questions and provide required assistance.
Best Regards,
Andrei
