I used to love this app, but now with hearts and stuff like that implemented, where if you make five mistakes in thrity lessons you have to wait 10 hours for a full refill, do better, or pay money. It also just throws you out there and expects you to know the words off the bat than a "teaching platform", to where you almost HAVE TO buy the plus version of the app. I got this app because I wanted to actually learn, not get ads for gaming PCs and paying money for family plus. C'mon Duolingo!
