Dear Sir,
I have read initial high level requirements and here is our technical team high level understanding:
You required to convert an existing Hybrid App written in Angular.JS, Cordova/Phonegap, ionic framework to Xamarin as rewritten from scratch with some additional functionality. All the APIs using JSON are to be provided by you in document format with complete details. You will also provide full specification and source code of the working hybrid version and access to a test database.
Here is the overview of your existing Hybrid App developed in Angular.JS, Cordova/Phonegap, ionic framework:
- The first takes the user through sets of questions/answers allowing them to enter comments and photos for each answer, this works online and offline. This needs minor modification to allow additional information to be entered for each answer that is mandatory based on certain criteria being met.
- The second is a data input screen with multiple photographs. This needs some slight modification but needs to be adapted to work offline and for improved error handling.
Here is our initial ballpark estimate:
- Hybrid App(Rewritten in Xamrin + Additional features): US $5,000
Please note that this estimate is for above mentioned features of existing App and 2-3 additional features mentioned by you. If you required other additional features, then the estimate will be revised accordingly to the additional features.
Look forward to hearing from you.
Regards,
YK
