I have been using Duolingo for a couple years to learn some Mandarin. Its resources are pretty good, if a bit dodgy here and there (some occasional weird pronunciations or translations).

I'm really excited about a Cantonese resource though. I have a few Cantonese-speaking friends and I would love to learn some myself!

Thank you :). Definitely feel free to use, download and share 粵卷 for your learning. I'll be continuing to make improvements to it over time. This is a life long project of mine so expect more improvements as my Cantonese develops.

I've seen weird tones, but IMHO the biggest limitation of Duolingo Mandarin is the lack of a traditional character option.
