Personal Motion Tracking Application

PMTA is a final generalization of what began life as the Green Travel Carbon Calculator and is now the Personal Carbon Accounting Domain app, PCA. It is the basis also of my Tweaks Sleep and Activity apps and is not focused on Carbon Accounting

GT2 is an Android and iOS app fulfilling the original app purpose which was frozen functionally at 2.0.8 when background operation was added and is free on Play and App Store. The PCA App, with cloud services sold in-app is the continuing development line. Versions thru 2.0.8 are public in my forgejo git repo.

This app has origins in the 2011 Green Travel Carbon Calculator which was a test of GPS on Android, the purpose for which it was originally created in fulfillment of a petty craigslist gig for someone unable to do same for a local NRDC branch in the Boston area.

Versions 2.n form a distinct line of development from the 2.0.8 baseline which runs in the commons app, also free but with services provided according to AKPERSON entitlement level.
