Garmin like Power/HR Graph
I switched from a Edge 540 to the Karoo and while especially Navigation is so much better, graphical representation of most of the values are subpar to say the least.
Since the Karoo is a simple Android device I chose to build the Garmin like graphs myself. I'm not a frontend or android dev but I can code and know my way around in software developement. With some vibe coding, tinkering with the results and debugging, it took me only half a day to get the first working version, another half a day for making it even better that the garmin version, you can switch between 1min/5min/full ride scaling.
Just wanted to say that while the Karoo lacks some Features that e.g. Garmin has (miss the stamina bar) it is great to have such an open device in 2026.
Edit: I will share it at some point, there is still some stuff to do and a few bugs.
