About

MyDeepNotes

Features
Read full description

MyDeepNotes is a PDF and handwriting notebook built for private tutors and the students they teach. WRITE ON YOUR PDFs Bring in question banks, worksheets and notes, then write straight onto them. Pen, pencil and marker; solid, dashed and dotted strokes; lasso selection and three kinds of eraser. Lines and shapes straighten themselves if you want them to. TEACH TOGETHER, LIVE Work on the same document as your student, at the same time. You send a link, they tap it, and you both write on the same page. Pen strokes appear on the other device as they happen. Your student needs no account and pays nothing. ASSIGN AND FOLLOW ALONG Assign a document as homework and see which pages your student has worked on. Only whether a page has ink — never what was written. KEEP REFERENCES WITHIN REACH Park a formula booklet, a periodic table, or any PDF you check often as a side panel. One tap opens it beside your work, one tap puts it away. MAKE NOTEBOOKS Grid, ruled or blank paper; pick a cover, set the page count. Notebooks stay organised in folders. ALSO • Links inside PDFs work — jump from a table of contents to the page • Type a page number and go straight there • Add, duplicate, rotate and clear pages • Paste images onto a page, then move and resize them • Open documents stay as tabs across the top • Your documents back up to iCloud No account needed. No ads. No tracking.
