Does anyone have recommendations for educational Go software, akin to the various quasi-gamified chess learning and training platforms emerging lately (PlayMagnus et al)? I'm not sure I have the mental bandwidth right now to work through books independently, but would love an app or other service I could spend a free minute or two on here and there.

I'm aware of Baduk Pop (https://badukpop.com/) but haven't tried it yet; there's also SmartGo (https://www.smartgo.com/) but it's Windows/iOS (with a MacOS version in the works) and I'm mainly using Linux and Android.
