Hi,I am iOS application developer and i am also doing master in engineering of computing systems fro Politecnico di Milano, Italy. I am taking the geographical information system course in which professor assign me a project to make a clone of ODK Collect application for iOS. I want to know that is any guideline or library available for iOS application development. I want to also know in which format the data is send to the sever and how to access the server? Thanks and regards,Hassan Shahzad ---

On this website [http://opendatakit.org/downloads/](http://opendatakit.org/downloads/), there is no download available for iOS of odkcollect. And one developer is claiming in the group that he has make the ODKCollect like application for iOS but the link he gives to iTunes does not work.

Hassan, Sounds like you've answered your question. The core team is not working on any iOS tools for ODK. A handful of folks in the community have tried and not been able to make sustainable progress. It's not impossible to port Collect, but I think most underestimate how much work it is. The JavaRosa library alone is 50k lines of code. Collect is 40k. I would guess it's $200-300k USD to do well, so you have to have a very strong business case for it. [https://groups.google.com/forum/#!topic/opendatakit/EaZYOfLiZ\_8](https://groups.google.com/forum/#!topic/opendatakit/EaZYOfLiZ_8) is the thread that discusses this in greater detail.
