Anyone who want to apply have to send examples of previous apps developed like uber, lyft, taxi apps, real time tracking, etc.
Must be an expert in native language for android or for IOS.
I have all the mock ups (wireframe designs) to make easier to explain, that way we can save time and avoid mistakes.
Please be clear if you can do one of the versions or if you want to work with another freelancer, etc.
The budget is only referential, all will depend upon experience and what the freelancer can have done. Don't be guided for that budget (give your own price I will evaluate offers/experience)
Always open to questions.
