Look Day Night Auto

Day is a quiet paper-white look for studying. Night is the dark look. Auto follows the iPad's setting.

Learner Child Teen Adult

Changes the words, the depth and the answer policy. Children get hints first and the answer only when they ask or are stuck. Adults get the answer with the reasoning.

Language

Listens Button Name Paper

Button: only while the button is held. Name: say the tutor's name first (“Elsa, ¿cómo hago esto?”); after a reply it keeps listening for a while without the name. Paper: no microphone; the tutor watches the paper and comments when something new is written.

Speech Cloud iPad

Cloud: Whisper, any language, detects the language, uses the daily allowance. iPad: Apple's recognizer, free, needs the language set above. The app switches to the iPad by itself when the allowance is spent.

Names

Button Left Right

Put the button on the side of the hand that is not writing, so it stays off the paper.

Paper

Only the part of the picture with the paper is sent, so the writing is sharp and the table is ignored. Find looks for the bright sheet by itself. Mark lets you tap two corners of the paper in the camera view, useful on a white table.
