## Solution
I didn't wanna to install this app, so I just decompiled it with jadx. There are a lot of files with code, but I didn't analyze all of it, I just watched it through in order to find something interesting. And here it is! In FourthActivity if found the following code:
![fourth_activity](./src/fourth_activity.png)
Seems like here your score compares to the best score. And if you scored more, base64 encoded flag will be printed.
Decoding the base:
