Description
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.
