My distance/speed isn't RIGHT

Our app does not have its own GPS system but uses the GPS in your smartphone. The app receives distance and speed from your phone. GPS chips (especially in smartphones) are not 100% accurate.

A SMALL DEVIATION?

Depending on your running conditions (between trees or buildings, next to a watercourse, your smartphone in your pocket, …) you will see that your smartphone does not follow your run path exactly, shows outliers or short periods without signal. This also causes deviations in the calculation of your speed and distance.

There is also a difference between devices, your GPS simply does not tell the exact truth. Even with a 'perfect' signal, deviations in distance and therefore also in speed are normal. So do not be too critical of your GPS reception.

BIG ERRORS?

In case of large deviations, where your distance remains much too high or much too low, you can dig deeper into the settings of your device. It can sometimes take some searching.

• Always turn off battery saver
• Turn off WiFi while running, or try it with WiFi
• Turn on your data… or off
• Turn off your device completely for a few minutes and restart it fresh

TIPS FOR SPECIFIC BRANDS

Smartphone manufacturers focus on battery life. That is why they often turn down the GPS reception or even turn it off when your screen goes off. You may be able to fix a few things using these tips. Settings under ‘Samsung’ can often be found on other Android devices. Still having problems? Contact the manufacturer via their customer service. They are often very happy to help you.
