Corvyn is an offline trainer for abstract reasoning: the matrix puzzles built from progressions, rotations and logical rules. It needs no account, shows no ads and collects no analytics. Practice works fully in airplane mode and your history stays on your device. Only two things ever leave it: a puzzle you flag as wrong (the puzzle and your answer, nothing about you), and with Gold, your synced history and leaderboard runs, kept under your subscription rather than your name. FREE, FOREVER — NOT A TRIAL • Practice at any difficulty you choose: easy, medium or hard, unlimited • All six rule types and all six shape arrangements — the whole puzzle pool • Every answer is corrected on the spot, with the name of the rule that produces it • Unlimited timed Challenge runs, with a score and a full item-by-item review • An ability rank from Novice to Elite, per-rule mastery, badges and a daily streak BRONZE — ONE PAYMENT, YOURS PERMANENTLY • Adaptive practice: instead of you picking a difficulty, Corvyn chooses each item to target your weakest rule SILVER — SUBSCRIPTION • Worked explanations: which features are held constant, and so why each wrong option is wrong • Drill one rule type at a time • Deeper analysis: trajectory, per-rule heatmap, calibration and retention • Challenge band placement: where each run puts you on Corvyn's ability scale • Run-over-run comparison: each Challenge run set against the one before, your recent average and your best GOLD — SUBSCRIPTION • Cloud sync: your history on every phone you use, and back with your purchase on a new one • Weekly leaderboard: your best Challenge run of the week placed among every Gold player's, with your percentile and the points to the next bracket, if you choose to join Prices are shown in the app, in your local currency, before you buy. Corvyn is an independent practice tool. It is not an official intelligence test and does not give a clinical or certified score.
