About Tolerence
Half of Tolerence answers one question: is this device actually working the way it should? The screen, keyboard, mic and mouse testers show you the raw numbers your browser reports, so you can judge the hardware rather than guess.
The other half is classroom equipment — grading scales, GPA math, spaced-repetition flashcards, seating charts and printable graph paper — plus two calculators for internet speed and download time. Every page runs locally and keeps what you enter on your machine.
