Edit: thanks for clarifying support for the Deck

There is “Oscilloscope” which can show frequencies and their intensity

Great, heard good things about OpenTTD! Do you game it directly on Steam Deck Controller or on Desktop with Mouse, Keyboard?

Thanks, I assumed so! :)

Great Game, for now i primarily play it on Android Phone. Easy to begin, but easy to die with one wrong click the game can be lost after hours of trying to get to the amulett!

Great Thanks for your write Up. I would love the idea that Steam Deck comes preinstalled with an Open Source Game like Xonotic!

FitoTrack may be suitable for that.

If the Map is not fitting totally you can even correct it on OpenStreetMap.org by yourself

FitoTrack is a nice open source fitness tracker which shows the path on OpenStreetMap background. It logs position and speed data.

You can create a custom workout which shows you the current speed instead of average.

How to watch YouTube on Steam Deck? Via Desktop Mode?
