I want to calculate user steps(like pedometer).I know that with iPhone 5s, 6 and 6+ we can use
CMPedometer or class(which use M7 chip of devices) but iPhone 5 and lower versions does not support M7 chip, so we can't use
CoreMotion. By searching all over internet i came to know that we can use accelerometer sensor for this purpose. But after spending a lot of time still i'm not able to make an accurate algorithm that works.
If anybody worked for this kind of algo can you please share their knowledge or atleast give link of good resources so that can RnD.
Thanks in advance.
