Structured arithmetic drills with measurable progress. 7 problem types, 3 difficulty tiers, Count or Time modes. Score, streak, accuracy and best — all on device.
Math Challenge is a structured mental-arithmetic trainer for users who treat practice as performance work, not entertainment.
Drill structure:
• 2 modes — Count (fixed 10 / 20 / 30 questions) and Time (fixed 30 / 60 / 90 seconds)
• 3 difficulty tiers — Easy / Medium / Hard, each with its own number range and operand cap
• 7 problem types — Add, Subtract, Multiply, Divide, Decimal, Negative, Mixed (default)
• 4 unique multiple-choice answers per question, no duplicates, no missing options
• Each mode binds an independent default difficulty (Count → Easy, Time → Medium); user-overridable
Measurable output:
• Live HUD: score, streak, remaining questions or seconds
• Final summary: score, accuracy %, personal best (per mode), full mistake review list
• Mistakes are kept until the next session for targeted retry
Engineering choices that matter:
• 100% offline. No outbound network at all. Cold start under 1.5 s on iPhone SE (3rd gen).
• English-only UI (CFBundleDevelopmentRegion = en) for clarity in international classrooms.
• iPhone-only build, portrait orientation, no privacy-sensitive APIs, no IAP, no ads, no IDFA.
• Whole-card tap targets for accessibility, dynamic-type-aware text, VoiceOver-friendly buttons.
If you want a no-frills tool that quietly tracks how fast and how accurately you can compute, Math Challenge fits in any morning warm-up, lesson break or commute.
