The description provides a broader picture of the app. Though all apps provide same functionality, (read/write data) but the size of actual project is not clear with the description. I wonder why everyone else has bid so much higher without knowing the complete detail.
I have worked with iOS since last 5 years and also working as a team lead (iOS) in reputed mobile company. As a developer, I had completed more than 50 projects including many iOS games.
I work part-time as a freelancer to earn a extra hand. I also have 2 developers who works part-time (like me) on iOS and we have great experience in making iOS apps.
I don't want to fake it so its better to mention that It might happen, after seeing the project size and amount of work, I may revise my bid for time and money so please if you plan to work with me, I would really need you to share the code earlier so that I may have a look at the actual work.
