Math homework starts with a question. Make the next step easier to understand with TwinSolve. Photograph a math problem, choose an image from your library or type the question. By default, two AI models work on the same problem separately, and their answers appear with steps side by side. Read both approaches, compare the working and ask about the part that still needs explaining. PHOTO TO STEP-BY-STEP HELP Use a clear photo of a worksheet, textbook, handwritten exercise or diagram. For a short equation or word problem, type directly instead. Recognition depends on image quality: keep the relevant question and its labels visible, and check the recognized text before relying on the answer. COMPARE THE WORKING An answer alone does not explain how to get there. TwinSolve displays the selected models' steps with short titles and mathematical expressions, so you can follow the transformations and compare different approaches. When the answers differ, a comparison check may identify a possible error and flag a step to review. These are AI suggestions, not proof that a particular answer is right or wrong. Matching answers can also contain mistakes. Use the comparison to decide what to check in your own working. ASK ANOTHER QUESTION Ask a follow-up about the selected solution, such as why a formula applies, how an expression was simplified or what a step means. With Pro, you can request a third model's solution for another perspective on a disagreement. MATH AND SCIENCE PRACTICE Explore algebra, equations, fractions, percentages, ratios, geometry, trigonometry, calculus, statistics and probability. TwinSolve can also help work through physics and chemistry questions. It is useful when reviewing homework, revisiting a worked example or discussing a difficult question with a parent or study partner. Practice at your own pace: attempt a problem first, compare the explanations, then work through it again without looking at the result. LISTEN IN YOUR CHOSEN LANGUAGE Read-aloud playback follows the solution step by step. Choose from 12 explanation languages: English, Simplified Chinese, Japanese, Spanish, German, French, Korean, Portuguese, Russian, Hindi, Vietnamese and Arabic. Your selection sets the language for new AI explanations and the playback voice; it does not automatically translate earlier saved answers. The interface has five languages: English, Simplified Chinese, Japanese, Spanish and Korean. Interface and explanation languages can be selected separately. KEEP YOUR STUDY NOTES Reopen saved questions and solutions in the history on your device, share solution text and mark the explanation you prefer. Votes record your personal preference. No account registration is required, and there are no ads. AI recognition and solving need an internet connection and send the question and relevant content to external AI services. See the privacy policy for details. FREE ACCESS AND PRO A daily free allowance is included; the current limit is shown in the app. Free access includes the default models and English, Chinese and Japanese explanation choices. Pro removes the daily solve limit and unlocks the additional model and all explanation languages. Available plans, local prices and any eligible trial are displayed before purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the period ends; renewal is charged within the final 24 hours. Manage or cancel subscriptions in your Apple Account settings. Deleting the app does not cancel a subscription. AI can make mistakes. Check answers and follow your school's rules for AI assistance.
