I want to create an Expo app for ios that will say something, and wait for my reply, via headphones. The headphones part is immaterial but it indicates what I want... which is for this to run while my phone is locked and in my pocket. Once I have replied, the app would proceed. I have built Expo apps but I am unsure of whether an app can still interact with me via audio and the microphone in this way while the phone is locked. Also, I don't know if Expo has introduced this sort of capability. I also don't know if React Native (i.e. ejected Expo apps) can do this sort of thing. The lack of apps that truly interact in this way (not via Siri etc) are far and few between so I'm assuming it's a hard problem to solve. I would be just as happy if I could have a browser page running on the device do the same thing, but I'm pretty sure webpages can't play audio and wait for replies when a phone is locked. Is any of this possible at this point?
I did research this online, just to be clear. I wasn't able to find an answer so I came here. I mention this because this whole post does have that 'can you research this for me' vibe. I'm just hoping someone has knowledge of what is possible.
