Red Sheet Support

You can fix it in Edit. Draw a box with Box around what you want hidden, and use Eraser to show what was hidden by mistake. You can also hide words by drawing a line over them with Marker. Pressing and holding an answer lets you choose Always Show or Hide, and Colors on This Page turns a color off. When you take the photo, use bright, even light, keep the page flat and filling the frame, and keep shadows off it. Settings › Accuracy & Limits explains what the app handles and its limits; for example, blue ballpoint may leave faint dots under the Blue Sheet.

Under the Red Sheet, red, orange and pink pen disappears, and words under a green marker turn dark and are hidden (a pink marker’s color clears). Under the Green Sheet, words under a pink marker turn dark and are hidden, and a green marker’s color clears (pen reads dark). Under the Blue Sheet, blue check pen disappears (blue ballpoint may leave faint dots). Choose the sheet, Full Page, Horizontal or Vertical, and Density in Sheet settings: tap the button at the top right of a page.

In Settings › Backup, tap Export Backup and save the file somewhere the new device can open, such as iCloud Drive in the Files app. On the new device, go to Settings › Backup, tap Restore from Backup and pick the file. You can also turn on iCloud Sync on both devices.

Turn it on in Settings › iCloud Sync on each device. Both devices must be signed in to the same Apple Account, with iCloud turned on.

Every feature is free. There is no in-app purchase, no subscription and no ads, and no page limit.

In the Settings app on your iPhone or iPad, go to Apps › Red Sheet and turn on Camera. On iOS 17, scroll down in Settings, open Red Sheet and turn on Camera.

Deleting the app removes everything it stored on your device. If iCloud Sync was on, delete the copy in your iCloud in the Settings app: Settings › [your name] › iCloud › Manage Storage. Backups you exported are your own files, so delete them where you saved them. More in the privacy policy.

iPhone and iPad, with iOS or iPadOS 17 or later. The app is in Japanese and English.
