ComputePrep trains your **quant speed**. Deduce is its sister app from the same makers, and it trains the other scored half: **reasoning** — one provably-correct logic puzzle a day, across 27 exam puzzle types. One Pro subscription unlocks both apps, and you can buy the Speed Book right here too — same makers, same account, signed in on both sides. ## Get Pro — one plan, both apps No card for the free week — every new account starts with 7 days of Pro on both apps. Cancel anytime from My Account. Want to try the reasoning daily first? [Solve today's puzzle free](https://deducepuzzles.com/play?src=from_computeprep) — or head back to [computeprep.com](https://computeprep.com). ## A coach on each side ### Saarathi Your reasoning coach. Ask "why is that the answer?" and he walks the deduction step by step, tracks which puzzle types cost you marks, and tells you what to drill next. With Pro: 120 coach turns a day (vs 60 free). ### Ganak Your quant coach on ComputePrep. After a drill he explains the fastest route — the vedic shortcut, where your method lost seconds. Everyone meets him on their first drill; Pro keeps him on every drill after that. ## What Pro includes — on both apps ### On Deduce - Past Puzzles archive - Adaptive practice — unlimited - Saarathi coach — 120 turns/day (vs 60 free) - 3 board hints per daily (vs 1 free) - Streak freeze — bank a spare (2) ### On ComputePrep - Unlimited practice drills (vs 20/day signed in) - Ganak coach on every drill verdict, not just your first - Same daily coach allowance — 120 turns/day Both dailies stay free forever, Pro or not — Deduce's daily puzzle and ComputePrep's three daily drills never go behind the subscription. ## How one subscription covers two apps - **Sign in with the same Google account** on deducepuzzles.com and computeprep.com. That shared sign-in is how the two apps know you're the same person. - **Get Pro on either app** — ₹199/month or ₹1,499/year, here on Deduce or directly on computeprep.com. Same price, same plan. - **The other app unlocks by itself.** Your Pro is recognised there automatically — no code to enter, nothing to link by hand, no second payment. ## Books & combos From ComputePrep ### The Speed Book The full edition of ComputePrep's drill book — every quant and logical-reasoning drill from the free 21-drill sample, plus the rest, with worked solutions and a target time on each one.
