Getting the best scan
- Sign with a dark pen on plain white paper.
- Photograph in even light and avoid shadows across the signature.
- If strokes look thin, raise the Ink strength slider; if specks of background remain, lower Background removal.
- You can always re-take the photo or import a different one from your library.
Signing a document
- Tap Sign a Document and open a PDF from Files, or pick photos of a paper document.
- Use the toolbar to place your signature, initials, text, the date, or a checkmark.
- Drag items into position and use the slider to resize the selected item.
- Tap the share icon to export the signed PDF (requires the one-time unlock; free users can preview the signed document).
Free version and the one-time unlock
The free version lets you scan, draw, or type your signature, save up to 3 signatures or initials, fill and sign documents, and preview everything on your device. Exporting or sharing a signed PDF, and sharing a signature as a PNG, needs the one-time unlock. The unlock also removes the saved-signature limit and adds approval and date stamps and the full cursive font collection. It is a single purchase, not a subscription; the price is shown in the app before you buy.
Purchases and subscriptions
- Bought the unlock on another device or reinstalled the app? Open Settings in the app, tap Upgrade to Premium, then tap Restore Purchases. Use the same Apple ID you bought with.
- If you subscribed to Weekly or Annual Premium in an earlier version, it keeps working. Manage or cancel it any time in your Apple ID settings: How to cancel a subscription.
- Refunds are handled by Apple through reportaproblem.apple.com.
Troubleshooting
- No signature found in the photo: try better lighting, a darker pen, or adjust the sliders.
- Camera not available: the app needs camera permission. Enable it in Settings, Privacy and Security, Camera.
- Signing a paper document: photograph the pages first, then pick up to 10 photos in Sign a Document. Each photo becomes a page of the PDF.
- Can't share or export: exporting needs the one-time unlock. If you already bought it, use Restore Purchases.
- Purchases not recognised: tap Restore Purchases on the Upgrade to Premium screen. Make sure you are signed in with the same Apple ID.
