iPhanpy brings everything that Phanpy has, but runs smoother, stays longer in memory, and has a neat Liquid Glass icon! I am not the original developer of Phanpy, so all props go to Chee Aun. I merely adapted the original web app into a version that is installable as a “native” iOS app - it faces way less performance restrictions compared to running on the browser.
