Aptly

Read full description

Practice for aptitude and psychometric tests with questions you can trust. Aptly covers numerical, verbal, logical, abstract, spatial, mechanical and diagrammatic reasoning, data interpretation and situational judgment, and every question comes with a step-by-step explanation and a time-saving shortcut. Timed mock tests, weak-area analytics and a daily habit, all working offline with no account. EVERY ANSWER EXPLAINED Each question has a worked solution that shows the method, not just the answer, plus a shortcut for doing it faster under time pressure and a formula card where one helps. Every question in the bank has been re-solved by hand and checked against its answer key. If anything still looks wrong to you, report it from the question in one tap. TIMED MOCK TESTS THAT FEEL LIKE THE REAL THING Choose an exam-style preset (Graduate CCAT-style, SHL-style, ASVAB / ADF-style military, Bank / Placement or Civil Service-style) or build your own with the sections, question count, time limit and negative marking you want. After every mock you get your score, an estimated percentile, a section-by-section breakdown and a full review with explanations. Then retry only the questions you missed. PRACTICE THAT FINDS YOUR WEAK SPOTS Untimed practice with instant feedback, by category and sub-topic. Accuracy by topic, your score trend, a weak-area heatmap and mastery badges show where to focus, and "Focus weak areas" builds a set from exactly what you keep getting wrong. Mistakes are collected automatically, and you can bookmark any question to come back to. A DAILY HABIT BEFORE TEST DAY A fresh Daily Challenge and streak, an optional reminder, a countdown to your test date and a readiness score that climbs as you improve. PRIVATE AND OFFLINE No account, no sign-up and no internet needed to practice. Your progress stays on your device. There are no ads on a question screen and none during a timed test. FREE TO USE, WITH AN OPTIONAL UPGRADE All 92 questions, every mock test, every explanation and all the analytics are free. Ads support the app. Aptly Pro is a one-time purchase that removes ads and the daily hint limit. It does not add or unlock questions, because nothing is locked. WHAT'S INSIDE - 92 hand-checked questions across 10 categories, including India-style reasoning: blood relations, coding-decoding, direction sense, seating arrangement, Venn diagrams, clocks and calendars and data sufficiency - Step-by-step explanations, shortcuts and 42 offline formula and tips cards - Hints that reveal the shortcut before you answer - Timed mocks with score, estimated percentile and full review - CCAT-, SHL-, ASVAB / ADF-, placement- and civil-service-style presets - Useful practice for cognitive ability tests such as the CCAT and Wonderlic - Weak-area analytics, score trend and mastery badges - Bookmarks, a mistakes log and retry-wrong sets - Daily Challenge, streaks, reminders and a test-date countdown - Calculator toggle, negative marking, light and dark themes Aptly is not affiliated with or endorsed by SHL, Criteria Corp (CCAT), Wonderlic, the US Department of Defense (ASVAB), the Australian Defence Force or any other test provider. Its questions are original, written in the formats these tests use.

About

Callback AI

Features
Read full description

Callback is finance interview prep for investment banking, private equity and venture capital — built the way a desk actually tests you. Free to start, and the free tier is a real one: you get questions in every one of the fourteen technical areas, not three areas and a wall. Every question carries a key takeaway, a full explanation, and a note on what the interviewer is really testing. Nothing is locked behind grinding through the basics — if you already know accounting, you can start on LBO on day one. WHAT MAKES IT DIFFERENT Numeric drills, not just flashcards. A purpose-built keypad, because in a real interview you are asked to compute, not to recognise. Frequency first. Every question is tagged with how often it actually comes up, and the ones you cannot avoid come first. A plan keyed to your interview date. Four phases from first pass to final polish, adapting as your mastery moves. Mock interviews you answer out loud. Pick one interviewer or sit a full superday — junior to senior, no break. Each seat has its own areas, pace and difficulty. Spoken answers are transcribed on your iPhone, and on an Apple Intelligence iPhone they are marked there too. Feedback is held to the end, like the real thing. Level calibration. Tell us where you stand and we believe you — then quietly verify with easier probes mixed into your day. Nothing is ever locked behind progress. An AI tutor that knows the syllabus. Ask a follow-up on any card and have it worked through rather than looked up. The tutor is answered by Callback, so every iPhone gets the same one — it is part of Pro, and the single part of the app that needs a sign-in and a connection. Live markets. The rates you get asked to quote, straight from the ECB, the Bundesbank, the US Treasury and the New York Fed — cached, so they still show on a plane. THE FOURTEEN AREAS Accounting · EV & Equity Value · Valuation · DCF · M&A · LBO · Fit & Story · Brainteasers · Markets & Products · Debt Capital Markets · Equity Capital Markets · Restructuring · Private Equity · Venture Capital FREE AND PRO Free gives you a genuine sample of every area, aptitude practice, and a daily plan built from it. Callback Pro opens the rest: every question in every area, the AI tutor, timed aptitude tests with a scored report, mock interview rounds, and the full plan through to your interview date. The split is by depth, never by grinding. WHO IT IS FOR Students and analysts preparing for summer analyst, off-cycle and full-time recruiting at investment banks, private equity funds and venture funds — and anyone sitting a technical finance interview who would rather be asked to compute than to recite. PRIVACY What you study stays on your iPhone. Your questions, answers, scores, plan and mock transcripts are never uploaded, and audio from a spoken answer is never stored — what survives an answer is text, on your device. The one exception is the AI tutor. What you ask it and what it answers are handled on Callback's server, and kept so a conversation has a history, which is why that feature — and only that feature — asks you to sign in. SUBSCRIPTION Callback Pro is an optional subscription, offered weekly, monthly or quarterly. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple Account settings. Terms of use: https://www.nocteventures.com/callback/terms/ Privacy policy: https://www.nocteventures.com/callback/privacy/ Every question in Callback was written from scratch for this app.
