OutRun: Open-source, privacy oriented, outdoor fitness tracker
OutRun

                Privacy Focused
                Admittedly there are a lot of running apps out there, many of which offer more features as in connecting with your friends or joining events or challenges, but that’s at the cost of your privacy. How you perform in workouts and especially where you ran, walked or cycled does say a lot about you as a person, so you should really think about who you will trust with that data. With this app your data stays in your hands. Nothing is ever uploaded to a server or shared with any other party as long as you don’t want to.
