Where should I start?
Save a few questions, select them in the practice-set workspace, choose writing space, and generate a PDF. Follow the first-sheet tutorial.
Can it automatically remove handwritten answers?
The current app provides a manual white brush, not automatic handwriting recognition or answer removal. Undo or restore before saving, and check that the question and diagrams remain intact.
Why is capture, import, or printing unavailable?
Import uses the system photo picker. Camera access is needed when you choose to take a photo. Check system permissions, or import an existing image when the camera is unavailable. Printing is handled by the system print service; check the printer connection and paper settings, or save the PDF and print it later.
Will I lose my material when the trial ends?
Trial expiry does not delete your material. You can still add, organize, and edit questions, and open, share, or print existing PDFs. Creating new practice PDFs requires the one-time Pro purchase. There is no cross-device app sync; export material you need before uninstalling.
How do I restore a purchase?
On iOS, use the App Store account used for the original purchase. On Android, use the original Google Play account. Choose Restore Purchases in the app’s settings or upgrade screen. Check your account and connection before attempting another purchase.
Why has an old PDF not changed?
A generated PDF preserves its original content. Editing a question or its status does not re-layout an existing file. Create a new sheet for updated content. Deleting an original question does not automatically remove its image from historical PDFs.
