My two cents: you have too many requirements that will cause paralysis. For example, don't worry about the Android or iOS idea yet. You are going to have trouble just getting the basic app done. Do that first and then you will need to throw it away once you understand what you need to build. If it were me, I would use svelte. Much better than react and satisfies your need for typescript. Use storybook for UI testing, just shift your thinking about that idea...
