About GPS

The accuracy of GPS is dependent on quite a few factors:

Differences in GPS chips between android and iOS Different GPS networks (whether the satellite network is Galileo, GNSS, GPS or another) Differences in GPS chips between different android devices (less so on iOS) Line of sight to the sky Weather conditions Having airplane mode activated, or not having data activated (GPS will work, but not as accurately in urban areas) Lack of other signals (cell tower, wifi, bluetooth) Time with GPS activated (longer is better) Echoes uses 'fused' location on android, meaning it will try to improve the location accuracy using as many sources as possible. On iOS, the device will do the same, but tries to save power by not using intertial movement sensors. Improved location accuracy is enabled for 3D walks on iOS devices.
