Hi, I have a complete product which is a appointment booking app in IOS,
and also Android. My IOS app is developed with native objective C, but however my android app is built using phone gap and codova. Currently the android app is only a shell/browser that runs .net pages from a server site. I wanted to change the android app to a complete native android app and all codes runs within the application. I will provide all api to make a booking, display branches and timeslot, view history, and all api that needed.
My app is running live in both app store and play store. you can search "Shawn Cutler" to download the app and check out more details.
please let me know what will be your professional charges and most importantly, how long you need to develop the application. If this goes well, i may need you to convert another IOS app too.
Hope to hear from you soon.
