If your GPS results appear to be inaccurate or if you're not able to get a GPS signal please follow these instructions:
1. Make sure you have installed the latest version of the Runtastic app (Runtastic, Road Bike, Mountain Bike, ...)
2. Restart your smartphone and make sure that you open the app with a visible line to the sky
3. Before you start tracking your next session, be sure to wait until there is a green GPS signal indicator. If not, open Google maps, iOS maps or Nokia / Bing Maps, then open the Runtastic app and let it search for 2-5 minutes for a GPS signal.
4. If none of the above work, it's possible the app did not download to the phone correctly, try deleting/reinstalling the app. Your activity history will be cleared from the device, so make sure that you sync all sessions to Runtastic.com beforehand.
Note: If you do experience a weak GPS signal and your activity tracking appears inaccurate, you can edit your session manually on Runtastic.com afterwards. Also due to the different built-in GPS receivers in each smartphone, we can’t guarantee exact tracking results.
When starting please try to avoid the following areas:
- High buildings
- Deep forests
- Areas where it's very cloudy
- Huge amounts of water like lakes, sea etc.
If you end up in the areas listed above then this can affect your GPS signal during your activity.
Be aware that just because the some map apps like Google Maps, Apple Maps etc. may show your location on the map, this does not mean that the device's GPS is functioning properly or that a GPS fix has been obtained. The data used to show your location on the map may be based on cellular network or wi-fi signals.
Note: Please find more detailed manuals for iOS and Android in each category.
