For families
PIN-protected parent dashboard, reward deals, multiple kid profiles on one device.

How a round works
Reviews first, then today's new questions, then bonus practice. Tap an answer, learn why, move on. Stop any time and keep everything you earned. The daily goal is a pace, not a cap: a kid on a roll can keep going as long as they like.
