OT abit. .. but if its just step tracking u need... cheapest ones I've used are the huawei band and the Amazfit t-rex...both are about 90% accurate...
weirdly even tho amazfit is under huami who also does for xiaomi.. xiaomi just plain sux...

as for the step counters in gshocks... just don't bother... highly inaccurate as per the many reviews u can find out there...
there should be a way to turn that feature off in gshocks to maybe save battery life as there are some nice models like the b100 mudmaster...
