Store description excerpt

Turn every mistake into progress. Errly is an AI tutor and error notebook for math, physics, and chemistry. Capture a problem from homework, a worksheet, or a textbook, then work through guided steps that explain the reasoning—not just the result. Save what you missed, review it before it fades, and practice the topics that need more work. CAPTURE AND UNDERSTAND • Scan handwritten or printed problems with your camera • Import images or PDF worksheets, or enter a problem manually • Follow the reasoning one step at a time • Try it yourself first, then use Check Mode to review your work • Ask a follow-up about the exact step where you got stuck • Compare another solution method when one approach does not click BUILD YOUR ERROR NOTEBOOK • Save the problem, source image, explanation, and error cause • Organize mistakes by subject and topic • Review with flashcards and spaced repetition • See the weak topics that deserve your attention PRACTICE FROM YOUR OWN MISTAKES • Generate targeted practice around weak concepts • Choose question types with Ultra • Search your whole error notebook by meaning with Ultra • Build printable worksheets from your saved mistakes with Ultra SEE YOUR PROGRESS • Use weekly, monthly, and exam-countdown reports • Export reports as PDFs to share with a tutor, teacher, or parent • With Pro or Ultra, turn on cloud sync to keep problems, photos, and progress across supported devices PLANS • Basic: no ads, more storage and daily practice, plus PDF export • Pro: unlimited error-notebook storage, watermark-free PDFs, cloud sync, detailed reports, follow-up questions, alternative methods, and more daily practice • Ultra: everything in Pro, plus unlimited practice generation, selectable question types, smart search, and printable worksheets Some features require an auto-renewable Basic, Pro, or Ultra subscription. Before purchase, the app shows the local price, billing period, trial eligibility, renewal terms, and full benefits. You can manage or cancel a subscription in your store account settings. Errly is built for study, not shortcuts: it helps you understand mistakes, organize them, and stop repeating them.
