How it works

Three steps. Zero manuals.

  1. 01

    Pick a deck

    Areas, fractions, percents — start without an account.

  2. 02

    Tap and flip

    Name and sketch on the front, formula on the back. One card, one idea.

  3. 03

    Rate yourself

    “Got it” or “again” — harder cards come back more often.
