Arithmadrill

Strengthen your arithmetic skills through focused, customizable practice. ArithmaDrill generates fresh math exercises for learners of any age. Practice addition, subtraction, multiplication, and exact division while building both accuracy and speed. Choose a quick session, set a fixed question goal, or continue with open-ended practice. START PRACTISING IMMEDIATELY Seven ready-made profiles are built in and free to use — one-digit addition, one-digit subtraction, addition and subtraction within 20, two-digit addition and subtraction, and open practice. Pick one and start; no setup required. CUSTOMIZE YOUR EXERCISES Create exercise profiles that match your current level and learning goals. Adjust how many numbers appear in a question, how long they are, which operators are used, whether results may go below zero, and more. Save your favourite configurations so you can start practising quickly. TRACK REAL PROGRESS Every completed exercise contributes to your personal progress history. Review your score, accuracy, and response time, compare recent sessions, and identify which operators need more attention. Share a summary card of a session you are proud of. FOCUSED, EXPLAINABLE RECOMMENDATIONS ArithmaDrill uses clear, deterministic rules — not AI — to highlight strengths, suggest an operator to practise, and show the evidence behind each recommendation. If you would rather hand the data to an AI yourself, export it to CSV. (If the characters look wrong in Excel, open the file with Google Sheets.) LEARN AT YOUR OWN PACE • Light and dark themes, or follow your device • Freshly generated questions every session • Addition, subtraction, multiplication, and exact integer division • Fixed goals of 5, 10, or 20 questions • Open-ended practice • Seven built-in profiles plus your own saved ones • Session results and progress trends • Detailed exercise history and CSV export • A guided walkthrough in Settings, plus a short video on building your own profile • English and Bahasa Indonesia • Offline-first practice with learning data stored locally on your device FREE AND PREMIUM OPTIONS The free version includes all seven built-in profiles, up to two profiles of your own, questions of up to three numbers and three digits with any two operators, progress statistics, a trend chart, and a focused recommendation. An optional one-time Premium upgrade — not a subscription — raises questions to nine numbers and five digits, unlocks all four operators at once and parentheses, and removes the profile limit. Premium also lets you set the digit length of each number in a question separately, cap how large the numbers may get, and open advanced filters, full analytics, and question-level history. Whether you are reviewing basic arithmetic, improving mental calculation speed, or creating a consistent daily practice routine, ArithmaDrill gives you a structured way to keep improving.
