Coming from RIF (is fun), I find voyager and jerboa to work well on android.

I’ll add on as someone that works with trans folks preparing for hormones/surgery, FFS is usually less common compared to other procedures, and is itself a cluster of surgeries that people may choose to do any combination of. Some of those surgeries are less drastic some are pretty intense (graphic warning: basically peeling back a portion of your face from your skull, changing bone and slapping that face back on). The more intense options are understandably not for everyone. FFS (and most other surgeries) usually comes into play after people give hormones a few years to do their thing and see where things end up. Let the canvas stabilize before working on it.
