PenPro is a notebook app for iPad, iPhone and iPhone Duo. Write with Apple Pencil, type, add pictures, tables and recordings, and place everything exactly where you want it on the page. WRITE AND DRAW • Write with Apple Pencil on lined, squared, dotted or blank pages, in A4, A5, US Letter or US Legal. • Draw a line, a circle, a rectangle or a triangle and hold the Pencil still: the shape becomes perfect. • Pens, colors, the eraser, the lasso and the ruler are Apple's own tools. TYPE AND ARRANGE • Text boxes with bold, italic, underline, four sizes, colors and lists. Align the text left, center or right. • Drag a text box by its corner, and its words grow or shrink with it. • Paste code, and PenPro colors it as a code editor does. • Tables you can resize, sort and total. Paste them from Excel, Numbers or a web page. • Pictures from your library, your camera or the clipboard, cropped and turned, with a border if you want one. • Move and resize everything with a finger. Things snap to the middle of the page and to each other. STICKERS • Five sticker packs, free: a red panda, a cat, an owl, a ninja and a penguin, with 44 stickers each. Put them on any page, move them and resize them. RECORD • One tap records a lecture or a meeting while you write. • When you play it back, your notes light up at the moment you wrote them. • Tap a note to hear what was said at that moment. HANDWRITING TO TEXT • Draw a frame around your handwriting, and PenPro turns it into text. Copy it, add it to the page, or put it in place of the ink. In English, French, Spanish, German, Turkish and more. SEARCH • Search the library: PenPro finds notebook names, page titles and the words you typed in text boxes, tables and code, and opens the notebook at that page. • "New notebook" and "Open a notebook" in the Shortcuts app and with Siri. Your notebooks and page titles in the iPhone and iPad search. NOTEBOOKS • Notebooks with sections and pages, in linen covers of sixteen colors. • Put your notebooks on shelves, one shelf for each category. Arrange them by hand, or sort them by name or by date. • Give a page a short title. It shows in the page list and in the table of contents of the PDF. • Lock PenPro, or one notebook, with Face ID or Touch ID, a PIN or a password. • Import a PDF and write on it. • Save any notebook as a PDF, share it or print it. • PenPro speaks English, French, Spanish, German, Estonian and Turkish. PENPRO EXTRAS One-time purchases. Each is yours forever, on every device with your Apple Account. • iCloud sync: your notebooks on every iPad and iPhone. • AI features: transcripts of your recordings, written on your device, and a handwriting font. • PDF notebooks: as many PDF notebooks as you want. One is free. • All three together, for less. IPHONE DUO • PenPro fits both screens of iPhone Duo: the iPhone layout on the outer screen, and on the large inner screen the page list beside the page. Its toolbars stay clear of the fold. PRIVATE No account, no ads, no tracking. Your notes stay on your device, or in your own iCloud. Recordings are written out and handwriting is read on your device.

Verdict
The clearest difference is ads: PenPro at none against AI Notebook's shown. AI Notebook's advantage is device support (5 vs 2) and iOS requirement (15.0 vs 26.0). On price, update cadence and in-app purchases there is nothing between them.
