Homework Eraser - Scan & Reuse

Just photograph the worksheet. The answers written by hand are erased and the sheet comes back blank, ready to be solved again and again.

■ Main features
・Erase handwriting: only what was written in pencil or pen is removed. The printed questions stay untouched (processed on your device; your photos are not sent anywhere)
・Detection strength: Light / Normal / Strong, plus a brush for touching up by hand
・Review Notebook: save a cropped problem you got wrong and solve it again later. The more often you get it right, the longer the gap before it comes back, and only the problems due today are shown
・Redo history: each sheet keeps how many times it has been solved again, and when
・Organise: rename a scan, set its subject, delete a page
・Save, share and print as PDF (AirPrint)
