Content that doesn't run out
201 flags. 190 vocabulary words. Real spaced repetition. Most brain-training apps repeat their whole library within 4–6 weeks — this one is built to last months.
A monthly reality check
A held-out assessment on tasks you never train, at fixed difficulty, every month — so a change in score means something more than getting used to the test.
No subscription tricks
Simple pricing, easy cancellation, no auto-renew traps.
