She says she's open to it but doesn't find it as intuitive. So there's a chance.
Could always try wefwef - I’ve been using the web app and it’s lovely! You just go to wefwef.app to access it, and there’s a place in settings where it walks you through how to set up a Home Screen icon so it works like a regular app. It’s very similar to Apollo as well :)
Hope you & your partner have fun with Lemmy! I am so far, trying to convince my other half to join up as well, haha 😛
