After intensive investigation of many tracking apps (Trails, Northface, Smartrunner, Runkeeper, Runtastic and more) I finally decided for Runtastic.
Criteria were:
- Low battery consumption
- Easy upload and sharing
Even though Runtastic has not the lowest battery consumption, it is the only app with reliable upload and sharing. The Runtastic portal is among the best.
