Feature overview

A compact but powerful math environment

HiPER brings many advanced features into a phone-sized interface.

Every calculation is done locally, instantly and with full precision — no AI hallucination, no cloud downtime. (We do use AI only where it is due - for optional image recognition on our secure server.)
