I want to create a Time and Task Management app where 20 co-workers would get tasks administered by 2 admins. This should be a hybrid app because it should work both on iOS and Android devices.
I personally was thinking about React JS as + Firebase as a solution, however I'm not sure if that would be the best direction to go in. I'd like to get an advice from experienced Web-App Developer, which combination of tools would you use? You can also see some attached MockUp Pictures.
Thank you and with best regards Daniels
