Love it!!

This is a perfect pedometer app for phones older that 5S with out M7 support. You can get very accurate step counts and distance reading by turning on the Detect Walk Function and playing with the Sensitivity and Stride length. I have mapped a 1 mile route with my car odometer and this app reads 1.055 miles. I also count 20 or 30 steps and the app is within 1 step plus or minus. Close enough for me. I have used it for 2 weeks now with out any issues of locking up.
