Invited to take a hiring assessment? Practice the visual logic formats used in modern recruitment tests — matrices, grids and symbol puzzles — and walk in knowing exactly what to expect. Logic Test Prep teaches you how patterns work instead of asking you to memorize answers. Solve original, procedurally generated logical reasoning questions, read clear explanations, revisit mistakes and track measurable progress over time. FOUR REASONING FORMATS - Code transformation — follow symbols through one or more rule changes. - Spatial deduction — complete 4×4 and harder 5×5 grids, with optional helper shapes. - Abstract reasoning — solve matrices with line cancellation, quadrant progressions, rotating signals, colorful rings and multi-step visual rules. - Inductive reasoning — work out the hidden rule from examples, then find the two grids that follow it. PRACTICE YOUR WAY - Choose focused sets of 5, 10 or 20 questions. - Set 20, 30, 45 or 60 seconds per question, or practice without a timer. - Enable adaptive difficulty to raise or lower the challenge based on sustained performance. - Mix all four formats in a balanced drill. - Bookmark difficult questions and retry saved mistakes. - Mark reviewed questions as understood and filter review by category. - Use optional helper shapes while solving grid puzzles. DIAGNOSTIC AND TIMED ASSESSMENT Start with a complimentary 10-question diagnostic to establish a baseline for your cognitive ability across all four formats. Timed Assessment gives you a fixed section limit, mixed difficulty, no answer feedback until completion and a final score report compared with previous attempts. PROGRESS THAT HELPS YOU DECIDE WHAT TO DO NEXT Review accuracy by category and difficulty, average answer time, improvement over time, strongest and weakest formats, recurring difficult questions and a recommended next drill. Every completed set includes a score, average time, change from your previous attempt, mistakes to review and a suggested next action. FREE AND PREMIUM The free version includes the diagnostic and 20 additional questions. It may show banner ads on the main screens and an ad after a completed set; ads never appear while you are answering questions. Premium is a one-time purchase, not a subscription. It unlocks unlimited practice and removes advertising, and supports Family Sharing. The App Store displays the price for your country or region. Restore Premium on another compatible device using the same Apple Account. PRIVATE BY DESIGN No account is required, and practice works offline.
