Markup vs eSign PDF
Markup is enough for a permission slip between Apple devices. For a lease, an NDA, or anyone on Windows, flatten it.

Questions people ask
Can I sign a PDF on iPhone without printing?
Yes. Open the PDF from Mail or Files, sign it with your finger, and send it back. No printer, pen, or scanner.
Why doesn't my Markup signature show on Android or Windows?
Apple Markup saves the signature as an annotation layer, and some non-Apple viewers don't show it. Flatten the PDF so the signature becomes part of the page. eSign PDF flattens every export.
Do I need DocuSign if I only sign documents?
No. DocuSign is for sending documents to others to sign (DocuSign Personal: $11/month billed annually ($132/year), 5 envelopes/month). If you received a PDF and just need to sign and return it, you don't need a DocuSign plan.
Do I need an account?
No. There's no sign-up and no login. Open the app and sign.
Does my PDF leave my iPhone?
No. Signing, filling and flattening happen on the device, and the app works offline. Optional iCloud backup goes to your own iCloud.
How much does eSign PDF cost in the US?
$59.99 one-time (US) for lifetime access. Your first export is free, so you can check the result first. Other plans and local prices are shown in the App Store.
How to sign a PDF on iPhone
PDF in Mail → sign → flatten → send back. Free Markup route and when it breaks.
Is Apple Markup enough to sign a PDF, or do I need an app?
When free Markup is enough, when signatures vanish on Windows, and when an app is worth it.
eSign PDF vs DocuSign: are you sending, or signing?
Send for others? DocuSign. Received a PDF to sign? $59.99 once, no account, vs $132/year.
