My friend told me about an idea she had for some healthcare software. I told her it’s a great idea and that she should get it built. She didn’t do anything with it for a month or two so I said I thought it was a great idea and wanted to get involved. I first said that I wanted to project manage for 10% equity. I find myself doing more than simply project managing and I’ve found a CTO who will take equity and cash. I asked if I could be a cofounder and my friend said fine to that. It seems like the idea is hers but that’s where her contribution stops. The rest of the work is mine and the CTOs. I feel like I want more equity to be more invested and maybe I deserve it. How much equity is fair for me to have?
Here is a resource that was recommended to me to address concerns about splitting equity. Perhaps you and your friend could benefit from checking it out as well

Do this. Start with a fair dynamic equity model, and it will quickly become clear that unless she contributes her share in the company will continually decrease.
