What's New in Penlog
1.3.6
November 4, 2026
Penlog now writes on iPhone Duo with Apple Pencil (USB-C). Open the Duo and tap Write. Folded, Penlog stays your phone companion: add tasks by voice or typing and read your pages. Opened, it starts on your tasks, and remembers if you choose the page. No Pencil on your Duo? You can choose to draw with your finger. Fixed a rare case where a stroke written just before switching screens could be lost.

FAQ
How does Penlog sync with Notion?
Penlog offers two-way task synchronization with Notion. Tasks written by hand become real tasks in your Notion database, and completing them in either app updates the status in both. This sync is automatic, eliminating the need for manual export or copy-pasting.
What are the benefits of Penlog Pro?
Penlog Pro unlocks additional destinations for your handwritten entries, including two-way Notion sync, calendar import, and access to the REST API and MCP server. It also removes the daily limit on handwriting reads for free accounts. Pro can be tried free for 14 days.
Can I use Penlog without an Apple Pencil?
While Penlog is optimized for use with an Apple Pencil on an iPad for handwriting, the iPhone app allows you to view today's entries, add and check off tasks, and read pages. However, the core handwriting input feature is best experienced with an Apple Pencil.
Does Penlog have ads?
Penlog does not contain advertisements. The app is free to use for basic journaling and task management, with optional Pro features available via subscription.
How does Penlog handle unfinished tasks?
Penlog features a 'carry-forward' function. If you do not complete a task on a given day, it will automatically be carried over to the next day's page, ensuring that nothing gets lost as you turn the page.
What is the 'Morning Briefing' feature?
The Morning Briefing allows you to connect Penlog with Notion, your calendar, Claude, or ChatGPT. Before you start writing, it places today's events and open tasks on your page. You can edit or hide these items before you begin your journaling session.
Is Penlog suitable for developers?
Yes, Penlog is designed with developers in mind. Every page is accessible via a REST API, and it runs a Model Context Protocol (MCP) server, allowing assistants that support MCP to read and write to your pages.
What is the update frequency of Penlog?
The app was last updated on November 4, 2026, indicating active development. While specific update frequency isn't detailed, the recent update suggests ongoing support and improvements.
