I’ve been using Duolingo to casually learn French. I also used school method (setup classroom with one email id and enrolled using another) to avoid ads, limited hearts, and leaderboards.

However, Duolingo has started showing ads and limiting hearts since last month for me. I checked reddit and seems like they’ve been rolling out these changes since last 3 months or so.

So I’d like to know what are the alternatives available for Duolingo?
