Just a simple but complete app that calculates the carbon footprint or savings of a trip. Intended for iPhone only with a later WatchOS extension.

This is the first iOS version of the Green Travel Carbon Calculator. 2.0.7 is feature complete except for optional background operation during a trip which will be introduced in 2.0.8.

After that the 2.0.n will be updates for changes in underlying support as it evolves and minor tweaks.

This version is calibrated to be within 5% of the accuracy of the measurement of a path on google maps. The minimum trip length is one quarter kilometer.
