Which reading tracker has which features?

The matrix

How do you read the stamps?

• On record: the app's own listing, website or help pages describe the feature.
• Not offered: those pages say the app does not have it, or the listing makes clear it is absent.
• Not in our sources: we did not find it on the pages we read. The app may still have it.

The method page explains each row and where the facts come from.

Why is there no total or score?

Because a column of stamps does not say which features matter to you. A club reader and an audiobook listener can look at the same matrix and want different apps. Counting stamps would rank apps by how much they publish, not by how well they fit you. The tracker finder uses your answers to order apps instead.

How is this different from the side-by-side table?

The side-by-side table shows each app's full card text, prices and sources, and lets you choose which apps to compare. This matrix shows only the stamps, so you can scan every app and every row at once.

Which rows separate the apps most?

Reading the matrix by row is more useful than reading it by app. On our cards, a few rows split the nine apps sharply:

• Picking a book back up: only Magic Bookmark is on record.
• Clubs and shared reads: on record for Fable, Goodreads, Literal and The StoryGraph; not offered by several others.
• Privacy label: split between apps that list no data used to track you and apps that list identifiers used to track you.
• Android: most are on Android; BookBuddy is Apple only, Literal lists Android as coming soon and Magic Bookmark has it on its roadmap.

Rows where nearly every app is on record, such as goals and stats, rarely decide anything.

What are the limits of a matrix?

A stamp says whether an app's own pages describe a feature, not how well it works. Two apps with "on record" for audiobooks may handle them very differently: a timer in one, a separate listening goal in another. Use the matrix to make a shortlist, then read the notes on each library card. The cards also show the date each fact was read.

How was the matrix last checked?

Every stamp comes from the app's own App Store listing, website or help pages, with the date we read it on the library card. The cards were refreshed in full on 2026-10-11; Magic Bookmark was re-checked on 27 October, 3 November and 4 November 2026, and Bookly's pricing note on 4 November 2026. If an app has changed since, the matrix will lag until the next quarterly refresh. The contact page takes corrections, with a link to the source.

Which rows matter for which reader?

Most readers need two or three rows, not all eight:

Ignore the rest until you have a shortlist of two or three apps; the other rows then break ties.

How do you check a stamp yourself?

Open the app's library card from the side-by-side table, find the row and follow its source link. Each stamp names the page we read and the date we read it. If the app's page now says something different, the app has changed since our check, and the contact page explains how corrections work.

What should you do with it?

Find the two or three rows that matter to you, read across them, and shortlist the apps with those stamps on record. Then read the shortlisted apps' profiles, which include their limits.
