Apps for AI Note 2 /WPD demo

Hi! This is my first e-ink device. My usage scenario: is office notes, editing, organizer, and transcription.

Question: what apps should I install? Which apps are best for this e-ink device? At a minimum, it can read and minimally edit docx, xlsx, pptx, and pdf files.

I see WPSoffice pre-installed and locked, I can't uninstall it. It's as if you're forcing me to buy the Pro version, since without it, WPS is just advertising garbage.

The stock features are great for taking notes and recording conversations. What's better for office files? Just no subscriptions, please! 🤣
