Iphone app - speed / performance measuring

I need an application that will use the g-force meter to measure the drag racing performance over certain distance. Several apps already exists that do exactly that, such as: Dynolicious, pocketdyno or revmeter. My favorite is dynolicious as it save vehicles and their performance. The important additional feature I need is to offer the user to send those information to my website database so I can show that data to the world and also offer them to update the data from there. Optional would be a synchronization of the data from the website into their app. No particular timeline on this project. I can wait for the most experienced programmer. I have a designer that can take care of all graphical aspects once the app is functional. Please send me link to previous apps you have made and a quote for this project. We can split the project in 3 A- same feature as competition app Dynolicious B- add sharing data to the webserver C- sync data from webserver to app That's it Happy bidding
