Iterating UI on device and simulator - should I switch to Figma?

I'm working on a hobby app, and even though I'm a software engineer at my day job, I have 0 UI or design experience. I find myself iterating in the simulator and on my test device to try to find my preferred design. I'm wondering if it would just be faster to mock up designs in Figma, find the design I like best, and then implement it.

Any engineers here use Figma? Is it easy to do the basics I need without spending too much time learning another SaaS tool
