Santa - AI TOEIC APK 4.13.4

5 stars: I enjoy this app everyday. No ads, many tests with elaborate explainations, evaluated by AI are some special features. But it will be better if u can change background color of answer, I find it's so difficult to read the white on the blue background.
5 stars: I really like the clear page and the analysis for our level, the courses for personally is very nice, hope not to have in-app purchase at the future... love it and perfect whatever.
4 stars: It's a pretty useful app and it improves my test grade. However, recently the app kept telling me that I don't have the authority to use it unless I purchase the class vouchers. And I was frustrated bc I couldn't find any links to buy it. Please fix it.
4 stars: the pictures on the listening part is monotone so its rather hard to see the correct point of the test but im just not sure if the real exam is using the same type of pictures or the application somehow chooses to use monotone picture
3 stars: I cant buy courses yet.
2 stars: I can't change the language of the app!!! Yes, I can read Korean but I wanted to use it in English as it is easier but there is no option to change language! Plus the app keeps lagging and showing me blank screens when I try to click things!
2 stars: How to re-turn on the LC option for the test? I have turned it off at my first test,but I wan to turn it back. I tried to look around in the app setting or reinstall the app. None of those helps.
