FAQ

How do I troubleshoot in Flowx?

Troubleshoot Process

If you encounter an issue in the app there are a number of steps you can take to eliminate the potential causes and get a fix.

Connection: check your internet connection if the issue is regarding data not loading correctly.

Restart: quit out of the app, click the Overview button (square button on the bottom right side of the phone screen), swipe out Flowx to clear it from the stack, then re-open the app.

Refresh: force a refresh of the app data by clicking "Refresh" two times via the top-right menu.

Clear App Data*: in your phone Android settings, go to Apps and select Flowx, then choose Clear Data from Storage.  

Uninstall* and reinstall the app.

*Important Note: this will clear your Place and Graph settings in the app, hence you may wish to Export these settings beforehand, to allow Import again afterwards - see Settings help page for more detail.

Why is data not showing on the map?

This is usually caused by a downloading issue. Either there is no network connectivity or it's flaky, the data server is down or the downloaded data is corrupted. Here are some steps you can follow to fix the issue:

Check your network is connected.

Exit the app using the back arrow and swipe it out of the list of open apps (via the Overview button: square button on bottom right of the phone screen), then open the app again.

In the top right menu, select "Refresh" and force a complete download if the option dialog is shown.

Clear the app data via the Android Settings > Apps > Flowx screen. (note: this will clear all your Place and Graph settings in the app, hence you may wish to export these settings to enable import again after clearing - see Settings help page)

If the problem persists, please contact us or send a Debug Log (see the Troubleshooting help page).

Why are the temperatures wrong?

Flowx shows the raw data from weather simulations. These global simulations are unable to resolve finer details at ground level, which can lead to a bias error in temperature. This bias is usually corrected using a technique called Model Output Statistics (MOS) and this is what you see in 99% of other weather apps. The disadvantage of MOS is that it is restricted to point locations where weather stations exist (airports, towns and cities), so you lose the spatial view of large weather systems. One day we would like to include MOS results in Flowx.
