Mobile teleprompters feel broken. Would you use a smarter one?

I’ve been thinking a lot about how most mobile teleprompter apps still feel off. They just scroll at a fixed speed, and you end up adjusting your speech to match the script instead of the other way around. It works, but it never feels natural.

I’ve been building Telea to solve this on desktop, focusing on a more fluid experience that reacts to how you speak. Now I’m considering bringing that same idea to mobile.

Before I do, I’m curious:

Would you actually use a teleprompter like this on your phone?
Do you see mobile as more useful than desktop in your workflow?

And beyond the core experience, what features would make this a no-brainer for you?
