Capture

Capture your ideas, notes, and research

The app opens on a text box with a Save button. Type your note, press Save, and the box clears so you can write another one. File the note under a category, a pen name and a book when you have a moment, or skip that and sort it later on your Mac.

  • Type and save, with nothing to set up first
  • File it under a category, pen name and book, or leave it unfiled
  • Share an article from Safari and the link is saved with your note
  • Add a second line of detail under the title, or just leave the title

Quotes

Collect quotes from sources and your own book to share on social media

Save a line from your own book or from something you are reading. If the line is not yours, record who said it. When you share a quote to Instagram, Threads, Bluesky or anywhere else on your phone, Calamus adds your book title and your buy link to the post.

  • Save quotes from your own book, or from a source with attribution
  • Sorted by pen name and by book
  • Share to any app on your phone
  • Calamus adds your book title and buy link to the post

Focus

Pomodoro timer for focused writing sessions

Pick a length from 5 to 90 minutes, in 5-minute steps, and choose a background photo from your phone. The app sounds an alert when your time is up, and you can add the session to your writing log with one tap.

  • 5 to 90 minutes, in 5-minute steps
  • Choose your own background photo instead of a stock image
  • An alert when your time is up
  • Add the session to your writing log with one tap

The writing log

Keep track of your writing habits and streak

Every session is recorded by day: the words added, the words removed, and the streak. A session can be assigned to a pen name and a book, or left unassigned for morning pages and anything else that belongs to no project.

  • Words written and words cut, by day
  • A daily streak
  • Assign a session to a pen name and a book
  • Or leave it unassigned, for writing that belongs to no project

It is yours

Your writing is yours, and exportable at any time

Nothing you write is used to train a model. There is no advertising identifier and no analytics SDK in the app. Everything you capture can be exported, and deleting your account removes it. If a subscription lapses, you keep reading, exporting and deleting what you already wrote; only new writing stops.

Available on the App Store
