Not accurate

I thought this app would be a good way to keep track of my steps for a friendly challenge at work. It has a user friendly interface and nice features. That it why is didnt get 1 star. When compared to Map My Walk which has been tested for accuracy during my half marathons, this app is completely off. I did the EXACT same track 2 days in a row. Day1 said I did 10000 steps and 4 miles. I actually did 9900 steps and 5 miles. I get that you have to adjust your stride length. I did that, and Day2 it said I did 5600 steps and 2.6 miles. This app is very inaccurate. The steps logged are independent of the stride, and lengthening your stride per step should have increased the distance, not shorten it. I wish I had not tried the pro version before testing. Wasted $1.99. Deleting the app.
