As long as I get energy back from watching ads but am not bombarded with other ads, I think the free version remains worthwhile. Sometimes I am getting bombarded with ads with no energy return, and that isn't nearly as good a user experience. Still wish we had discussion boards back, those were as valuable as the lessons themselves. I'd probably pay if those were part of the premium version.

Gets worse and worse, saying this is free is false advertising. I have been with the app for 5+ years, and now the "charges" instead of hearts are terrible. Doesn't matter if you make no mistakes you still have to watch ads or you will run out of "charges". You used to be able to just practice for hearts. Then it was ads, for hearts. Now it's these "charges" that run out after 1 lesson if you don't watch adds. Will be looking into other free language apps now. Been going downhill for awhile.

I like the app overall, but the new energy system is weak. you run out of energy even while being correct. I can't study as much as I could with the heart system. and now the whiteout survival ad doesn't have any way to close it at all, you have to quit the app and reopen it. destroying the app like crazy this month. dropping my rating to 2 stars. now another ad can't close no matter what. I guess I can't rate any lower than 1 star. my next step is uninstall and try airlearn.
