Pencil brings handwriting, sketching, PDF annotation and watercolor painting to iPad and iPhone. Designed especially for Apple Pencil on iPad, it also works with other compatible styluses and your finger. Take notes in class, mark up a document, plan your week or paint an idea while it is still fresh. • Write and sketch your way. Use Apple Pencil on iPad, or write and draw with a compatible stylus or your finger on iPad and iPhone. Start a PDF note from a paper template, choose your ink colors and add typed text, images and shapes. Use lined or grid backgrounds to give your notes structure. • Make your PDFs useful. Highlight passages, add comments, write in the margins and insert your signature. Search inside a document, bookmark important pages and rearrange, duplicate or rotate pages as your work develops. • Keep the conversation with your notes. Record audio directly in a PDF note and play it back alongside the page. Revisit a lecture, meeting or explanation without separating the recording from your written notes. • Type when words come first. Create formatted Text Notes with fonts, colors, lists, checklists, tables and images. Turn a quick thought into a clear set of notes, a plan or a longer draft, then export it as a PDF to share. • Explore watercolor painting. Open a dedicated painting workspace, choose your paper and experiment with brushes, mixed colors and washes. Paint from a reference photo, try guided practice lessons and export your painting as an image or PDF. • Bring paper into your notebook. Scan documents with the camera, import files through the Files app and add photos to your work. Keep notes, PDFs and paintings organized in folders, ready to return to when you need them. • Get help from AI.

Verdict

The call

The clearest difference is review sentiment: pdf at 68% against Pencil's 25%. pdf also leads on ratings volume (22 vs 4) and iOS requirement (16.0 vs 26.0). Pencil's advantage is rating (4.0 vs 3.3) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. pdf sells 3 one-off in-app purchases and Pencil sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Pencil holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: pdf has 22 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 68% of pdf's written reviews are positive against 25% of Pencil's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

pdf ships an update every 3 weeks, Pencil every 8 days. The most recent releases landed on October 10, 2026 and October 11, 2026 respectively.
