I haven't seen Soulver, but it looks very similiar to the one I use on Mac, called Numi. On Android, I use an app called CalcNote which works in a similiar way.

I haven't seen Soulver, but it looks very similiar to the one I use on Mac, called Numi. On Android, I use an app called CalcNote which works in a similiar way. Neither does graphing, but you can do common formulas and functions like cos/sin/rad. I use numi for simple calculations, and find it fantastic when I'm trying to figure out project stuff. A recent use is entering wall dimensions to figure out square footage and compare different building materials. I often leave most of my old calculations in numi like a long-lived numerical memory. https://numi.app/ https://numi.app/ https://play.google.com/store/apps/details?id=com.burton999.notecal.pro https://play.google.com/store/apps/details?id=com.burton999....
