Moves for iPhone doesn’t track my steps indoors

If you have Battery Saving mode enabled in the settings then Moves will go to standby mode inside places. When Moves is in standby mode it doesn't track steps unless you have a phone with hardware step counting (specifically iPhone 5s). 

If you use Accuracy mode note that very short walks (less than 30 sec) are not always counted, except on iPhone 5s.
