Hello There,
We can do this project for you very easily as we have done similar calculator apps earlier. Also, I was personaly involved with this UK CO2 calculator you want to copy at consultation stage.
Having said that, we assume that you will not expect similar level of graphics in the mobile app (and provide us with lighter UI) and will give us the formulae to calculate the CO2 footprint.
We are happy to work under NDA and will give full source code to you upon full payment.
Please name your price to award this project to us and we will accept it unless it is very, very low.
Thanks
