Redleaf
Help & frequently asked questions
What the app does
Redleaf is the red-sheet study method on your phone. Many study books print the answers in red or orange so that a
red plastic sheet hides them. Photograph a page, and Redleaf hides those answers under a digital red sheet that you
slide down line by line, or tap to reveal one answer at a time.
Getting started
- Make a notebook for a subject (+ on the notebook list), or tap
Add sample page to try the app with a page written for it.
- Add a page. In the notebook tap +: Scan with camera finds the
page edges and straightens the photo; Choose photos takes pictures you already have.
- Check the hidden answers. Red and orange print is found by its colour and shown with red boxes.
Move the Sensitivity slider if pale ink is missed or stray colour is picked up, then tap
Save.
- Study. The page opens under the red sheet. Drag the handle at the sheet's edge down to uncover
the page line by line, tap a hidden answer to see just that one, or tap Show all. Pinch to zoom.
Questions
Some answers were not found, or the wrong words are hidden
Open the page and tap the highlighter (top right). In Auto, raise the sensitivity for pale or thin
ink, lower it if coloured pictures are picked up, or choose Orange marker for words you highlighted
yourself. With Marker you hide any other word by drawing over it with one finger (two fingers move and
zoom); Eraser removes a hidden answer, and the arrow undoes the last step.
The photo is dark or yellow
Redleaf corrects the colour of the light before it looks for red, so a desk lamp or a window is usually fine. Very
dark photos lose their colour: take the picture in a brighter place, and hold the phone flat above the page.
Does Redleaf read the text?
No. It finds coloured print by colour alone. There is no text recognition and nothing is sent anywhere.
How does the review work?
With Pro, every hidden answer becomes a card. Review in a notebook shows the answers that are due
today, one at a time, zoomed in on their line. Tap Show answer, then Got it or
Not yet. An answer you know comes back after 1, 2, 4, 7 and then 15 days; one you did not know comes
back tomorrow. The number on each notebook is how many answers are due today.
My book prints the answers in green
With Pro, choose the green sheet (or any colour) in Settings, and pick Green or
Blue in the page editor so those inks are found.
Can I import a PDF?
With Pro: in a notebook tap + › Import PDF. Every page of the PDF becomes a study page.
What is free, and what is Pro?
Free: 2 notebooks with up to 20 pages each, automatic red and orange detection, the marker and eraser, and the red
sheet. Pro is a one-time in-app purchase that adds unlimited notebooks and pages, spaced review, the
green sheet and your own sheet colour with green and blue ink detection, drawing with Apple Pencil on iPad, and PDF
import. There are no ads and no subscription.
I paid but it is still locked
Open Settings (the gear) and tap Restore Purchase, signed in with the Apple Account
you bought with.
Can I get a refund?
Refunds are handled by Apple: reportaproblem.apple.com.
What data is collected?
None. There is no account and no ads, and the app does not use the network apart from the App Store for the
purchase. Your page photos stay inside the app on your device; deleting the app deletes them. See the
Privacy Policy.
