Hello, hope you're doing well!
I really like the idea of the app that you want to build, it would help me a lot when I was a student! I can create the app in angular, and make it as PWA as I have experience in the field. Mobile responsiveness is not an issue ofc. Just one question, do you have a design for the app already?
I can make the design as well, and I bid the price in a sense that I will make design mock ups as well.
Hope to hear from you soon, and have a good day :)
