I'm in week 8, starting "Problem Set 6: (Mispellings)". I would like to start working on my final project and my idea is to create an Android app that should include a chat, similar to the Tinder app but based in common interests. I have some background in Java/Android (just the basics) and I was wondering if creating such an app is achievable with what we are learning/going to learn in CS50. Is something like that too difficult at this level?
Maybe no, maybe yes, now this is something that depends on your skills and well, it might as well take you some more time, but I think it's fun learning, so I personally highly recommend you learn the stuff. And as for help, I highly recommend you see existing apps and frameworks for help, for example, for using chat, see AirChat which you can probably modify or even recreate in a different way for your app, and do remember, if you use some existing app for inspiration, make sure you credit that to your final project.
