Measure your RQ in 2 minutes, train it in 3 minutes a day. No ads. No subscription traps — lifetime option available.
Kivrak measures how fast and accurately you think under pressure: a 3-minute daily sprint, one RQ score. No ads, no subscription traps, lifetime option available.
WHAT IS RQ?
RQ (Reasoning Quotient) is a single score computed from accuracy, reaction time, and difficulty level. A 2-minute test measures it on first launch and compares you with your age group: "Faster than 72% of your peers."
3 MINUTES A DAY
Each session is 3 games × 60 seconds. Difficulty adapts to your performance. Questions are generated procedurally — the content never runs out, and you never see the same question twice.
5 EXERCISE CATEGORIES
• Quick inference — which one breaks the rule?
• Decision speed — which offer is the better deal?
• Logic chains — does this conclusion follow?
• Mental flexibility — adapt when the rule changes
• Numeric intuition — which is bigger?
PROGRESS, EXPLAINED
We don't just say "you scored 142." Your weekly report speaks plainly: "You're slow but accurate on logic chains — speed training recommended." Your speed/accuracy trade-off is visible on a chart: are you rushing into mistakes, or playing it too safe?
HONEST PRICING
• No ads. No locked-content surprises.
• Try free for 7 days; then a yearly or monthly plan.
• Don't like subscriptions? Lifetime option: pay once, keep it forever.
EVERYTHING ON YOUR DEVICE
Works offline. No account, no sign-up, no personal data collected.
Note: Kivrak doesn't promise to make you smarter. It measures and trains how fast and accurately you think under pressure — and you watch your progress in the data.
