The accuracy of location reporting mainly depends on whether the app can get proper satellite coverage. Problems might occur, either when being indoors or close to tall buildings. There are other factors that influence accuracy as each device’s GPS accuracy may differ.
Other apps might have a few meters better accuracy by enabling a constant GPS flow. However, these apps will drain your phone’s battery fairly quickly. Normally, Safeture gets an accuracy of around 100m to keep the battery consumption at a low level, and in order to ensure a good balance between accuracy and battery consumption.
