Point your camera at a study guide. Your iPhone becomes a smart red study sheet. Hide red answers quickly and make memorization smoother. Check what you truly remember right where you study. SmartRedFilter is a memorization study app that uses your iPhone camera to hide answer text such as red writing while you look at your learning materials. A key benefit is that it can automatically recognize red text and hide the answers without turning the whole screen red. Black text and the rest of the page stay easy to read, so you can focus on the answers you want to recall. No need to carry a physical red sheet. With just your iPhone, you can review whenever you want. Point the camera at study guides, workbooks, vocabulary books, exam materials, and more to cover answers and keep your study rhythm moving. It is useful beyond printed books too. You can also hide text you wrote yourself with a pen or similar writing tool. Write answers into notes or worksheets and turn your own materials into custom memorization practice. "Recall before you reveal." That small step matters when you want knowledge to stick. With SmartRedFilter, you can hide answers as you study and turn passive reading into active recall. ■ Great for - Hiding red answers in study guides - Exam prep, school tests, and certification study - Memorizing vocabulary, terms, dates, and formulas - Reworking problem sets without seeing the answers first - Reviewing notes or worksheets with your own written answers hidden - Quick red-sheet style review away from your desk ■ Features - Study directly through the camera - Hide red text while keeping the page readable instead of tinting the whole screen red - Cover answers with a red-sheet style workflow - Use printed books, handwritten notes, and your own study materials - Reveal and hide answers quickly for checking - Adjust the view to fit different materials and lighting - Start memorization practice with the iPhone you already carry ■ Made for - Students preparing for entrance exams - Learners working through certification and license exams - Anyone who wants to review during commutes or short breaks - People who like red-sheet memorization - Learners who write answers themselves to remember them better - Anyone who wants to get more value from the study materials they already use Studying is easier to continue when it is quick to start. Make your usual books and notes into a more convenient memorization tool with SmartRedFilter.
