I never expected this to be 100% accurate but I've been using this for a few months and it syncs with myfitnesspal so I figured this app was a win win for me. That's until I decided to run a 3 minute test of doing nothing to see how this app would record my activity. The outcome: It shows that I walked .02 miles, burned 18 calories, and it mapped out my walking pattern. Again, I didn't move at all. I'm not using this app again. I can't trust the results at all.
