Litmus

A book log first. A mirror second.

Litmus is a reading tracker that does the ordinary things well — shelves, stats, streaks, and clubs — and one thing nothing else does: it shows you the representation across your reading, quietly and without judgment.

Free to start. Import your library from Goodreads or StoryGraph in minutes.

What it does

Everything you expect, plus a view you can't get anywhere else

Track

Every book, on one shelf

Log what you're reading, what you finished, and what's waiting. Ratings, reviews, dates, and page counts live on a clean shelf that works the same on the web and on your phone. Your data is on your device even before you make an account.

The representation in your reading, made visible

Litmus reads the signals already attached to your books — authors and themes — and shows you the mix across your shelf. It's conservative by design: it never guesses at a person, and it never scolds. A quiet picture of the range of voices you're actually reading, and the ones you're not yet.

Bring it all

Import from the app you're leaving

Moving off Goodreads or StoryGraph? Export your library, drop the file into Litmus, and your shelves, ratings, and reading dates come with you. Currently-reading and did-not-finish states are preserved, not flattened.

Streaks, badges, and book clubs

Reading streaks that survive a busy week, badges worth earning, and clubs where a small group reads together — the parts that make a habit stick, without turning reading into a leaderboard.

habits, not leaderboards
