Useful Categories to group Apps on iPhone, iPad?
What would be some useful categories into which I could group the apps I have on my iPhone (or iPad) for example, put all my audio monitoring apps (tuning, sound pressure, equalizers) in one category, but put sound sources (radios, streaming sources) in another, ... etc.??? "Games" is obvious,... what else do you use for arranging your apps?
Am I being mentally lazy? I plead too many apps make s it confusing... the categories seem to overlap. So have you got some useful suggestions?
