Hi there,
I've been running for almost 7 years, also, I am a developer, and as a hobby on my spare time, I created Android app for tracking location, to count distance, calories, etc.
Would be nice if someone here can try my app:
play.google.com/store/apps/details?id=com.aneze.run
Did you like it? How's it? What would you improve? Don't be too critical, as it's first version only.
Please post your feedback here in this thread, not on Play store, I won't check it there.
Thank you.
