GPS Troubleshooting Guide

• Enabling GPS Tracking on Your Device
• Granting Zeopoxa app Permission to Use Your Location
• Why do other apps show my location but yours does not?
• Why does your app not work with my device's GPS?
• Treadmill, Indoor Cycling
• Distance vary on same route/is different to my friends’ phone
• Max speed is too high on workout
• Total ascended/descended elevation - calculation method

Enabling GPS Tracking on Your Device:

• Open the phone’s "Settings" app
• Select "Location" and ensure that it is enabled, and that you have selected to use GPS, Wi-Fi, and mobile networks. Enabling all three or selecting "High Accuracy" mode is required for accurate tracking.
• From the "Settings" app, select the "Date and time" item and ensure the "Automatic date and time" and "Automatic time zone" check boxes are checked. GPS and our app rely heavily on an accurate time and time zone. Having your device set to the incorrect time zone or time, may prolong the time taken to obtain a GPS fix, and may result in other inaccuracies in your recorded workout stats.
• Many new smartphones use a “Smart Manager” or similar kind of power saver, which might cause your app to crash, or interfere with the GPS tracking. For detailed information on deactivating the power saver on popular devices, see here.
• Optimization might block some of the functionality of your app so we recommend all our users to disable it if is enabled. For guidance on how to disable optimization for popular devices, see here.
• Ensure that the GPS signal indicator is green before you hit start. Try to avoid starting your activity in areas where there may be a weaker GPS signal, i.e. near high buildings, deep forests, or near huge amounts of water like lakes or the ocean.

Granting Zeopoxa app Permission to Use Your Location:

When you first install the Zeopoxa app, we will ask your permission to use Location Services. Double check this permission has been granted by:

• Open the phone’s "Settings" app
• Tap "Apps" to view a list of applications you have installed
• Scroll to Zeopoxa and select the Zeopoxa app(s) you have installed
• Tap "Permissions"
• Make sure that "Location" is toggled on

If you are still having GPS issues after the steps above, try these additional steps that are known to resolve almost all issues:

• Restart your phone regularly. Usually holding down the power button and selecting "Reboot" or "Power off" will do this.
• Remember you must be outside with a clear view of the sky when your device is searching for a GPS signal.
• Ensure you have a good internet connection when your device is first searching for a GPS signal. Your device may need to use the internet to obtain hints that will greatly reduce the time it takes to find your location.
• Activate then deactivate “Flight Mode” (“Airplane Mode”) – In some cases this may help you get GPS working again.
• Open Google maps, then open the Zeopoxa app and let it search for 2-5 minutes to lock onto a GPS signal.

If you do experience a weak GPS signal and your activity tracking appears inaccurate, don’t forget you can always edit your activity manually

Why do other apps show my location but yours does not?

Please be aware that just because other apps like the "Maps" app or our app may show your location on the map, this does not mean that your device has a GPS signal or a GPS location fix has been obtained or that it is functioning properly. Other apps may use cellular network or Wi-Fi based estimates to show your location on the map, these estimates are not sufficient for tracking activities like walking, running or riding.

Why does your app not work with my device's GPS?

Android only allows our app to turn your device's GPS hardware on and off. Our app does not have permission from Android to diagnose and fix issues. The quality and time taken to find a GPS signal is dependent on your Android device and its manufacturer.

Treadmill, Indoor Cycling

Please note that if you're using one of the above sports, the app cannot track your distance because you're physically remaining in the same place. If you are using one of these sports, you can add the workout manually by going to "History" and tapping the +button. You can then enter the workout details from the computer on the treadmill.

Distance vary on same route/is different to my friends’ phone

The GPS hardware in the phones can differ from phone to phone. Some phones are better at picking up the satellite signals and pinpointing the actual position and are therefore, more accurate than others. It is always possible that wrong track points will be picked up by the phone. To minimize the error margin, we filter all track points to remove as many errors as possible. In general, distance tracked by GPS should only vary within 0-2% if there is a good satellite signal

Max speed is too high on workout

The max speed shown is too high on my workout details, why is this? The speed is calculated from the track points we collect through the GPS. But since GPS is not 100 % accurate it can pick up track points that are a bit off. This will mean that the GPS thinks you have moved farther than you have, which results in a higher max speed. We try to filter out these track points to get a more accurate route and speed, but this is not always possible. The max speed can look very high sometimes, but the average speed should still be correct as the max speed error is only in accordance with one track point.

Total ascended/descended elevation - calculation method

To calculate the total ascended and descended elevation we sum up all the ascents and descents the GPS picks up while tracking. Ascended and descended elevation is calculated for all sports where we have elevation data. Manually entered workouts will not include elevation data. Due to GPS errors we try to filter out any fast occurring changes that seem unlikely, but this can also result in an underestimation of the elevation ascended/descended. We will continuously work on improving this as GPS devices become more accurate.Altitude from GPS data can be inaccurate by about +/- 25 meters / 80 feet at each track point.
