I used to really love this app, but with each new "improvement/update" it's gotten helpful and more frustrating. I am a broke college student and can no longer pay for the subscription. Now unless I want to spend hours watching videos to get energy or spend a lot of diamonds to buy energy, they only give you enough for one round. I am seriously considering letting my 1175 day streak go and uninstall the app altogether. I will wait to see if they make any changes to fix this issue.

The app has become extremely buggy. I constantly have to close and reopen it to update my progress after finishing a lesson. Sometimes, it will erase two or three full levels of progress. Last night, I needed to pass a test to be permitted to return to where I belonged. It will also say I have 3x XP for 30 minutes, which somehow turns out to be 1.5 XP for 10 minutes. I've submitted multiple bug reports without any reply or, worse, any signs of a fix.

I used to love this app. I've been using it for over a year, but they've disabled "practice to earn more hearts" in the free version. I thought it was a random bug, but it's happened to a couple of my friends with long streaks too. I think it's their way of getting people to do the paid version. We've all sent in bug reports but havent received any responses and theres nothing on the website. It's been a couple months. Without that feature, it's almost impossible to do multiple lessons in a day

I have a 1,364-day streak. I just got switched from the heart to the energy system and it's awful: I can't even complete one "legendary" lesson without running out of energy, usually at the very last question (of course). Obviously a ploy to force learners to subscribe to the paid app. Every recent change has been for the worse (repetitive lessons, no explanations for mistakes, etc.). I was reluctant to let my streak go, but this does it.
