Does the app need an internet connection?
No. Everything is built into the app, so it works fully offline,
including on a plane or in the car.
How do I switch the narration to Mandarin?
Tap the "EN" button in the top-right corner of the home screen. It switches to
"δΈζ", and the app remembers your choice.
Is any account or sign-in required?
No. There's no account system β just open the app and play. See the
Privacy Policy for details on what data is
(and isn't) collected.
