Apple ships the iPhone Duo on October 23. Here is what is known, with sources, and I’ll keep this first post updated as Apple says more.

**What Apple has said.** Pencil support is “coming later this year.” Apple’s page names one model, the Apple Pencil (USB-C), and doesn’t say which display it works on. It is not there at launch. Source: the FAQ on [Apple’s iPhone Duo page](https://www.apple.com/iphone-duo/).

**Which Pencil.** Apple’s page names only the Apple Pencil (USB-C). If you own a Pencil Pro or a Pencil 2, check before you count on it. [Engadget](https://www.engadget.com/2255122/use-apple-pencil-with-iphone-duo/) says only the USB-C model is compatible, and guesses the reason is that the iPhone lacks the magnets to attach and charge a Pencil. Apple has not explained.

**What is only reported.** Apple has not confirmed a version or a month, and these are guesses. Engadget expects the update with iOS 27.2 around November. [iDropNews](https://www.idropnews.com/rumors/iphone-duo-apple-pencil-support-plan-b/268705/) thinks it may wait for iOS 27.3 in December, and relays Bloomberg’s Mark Gurman saying it will be “fairly late in 2026.” [BGR](https://www.bgr.com/2260474/delayed-ios-27-feature-iphone-duo-incomplete-apple-pencil/) calls the date “undetermined.”

**What Penlog is doing.** Version 1.3.0 installs on the Duo as an iPhone app (I’ve checked that on Apple’s simulator, and I’ll check real hardware as soon as I can). Writing on a Duo will come in a later release, once Apple releases Apple Pencil support for the iPhone Duo.

- Are you getting a Duo? Is Pencil support part of why?
- Do you own an Apple Pencil (USB-C), or a Pencil Pro or Pencil 2?
- If you could write on a Duo, what would you want a handwritten journal to do there?
