This is what Lecturameter tracks for you

Six metrics the app calculates from every session you log. Nothing is made up: if there's no data yet, it doesn't show.

Reading daysHow many days you've been reading this book
Total timeHours and minutes accumulated
Pages readHow much you've read so far
% readHow far into each book
Pages/dayYour real reading pace
Pages/minYour speed with the timer

The timer works beautifully even with the screen off.

Real screenshots. This is the app.

Three pillars: library, timer, and statistics.

Library with shelves

Your books in your private library.

Five shelves to organize your books by status.

  • Search by title, author or ISBN
  • ISBN scanner
  • Full detail: cover, genres, editions
  • Lecturameter remembers the page you left off on so you don't lose your progress
Automatic CSV import. Coming from Goodreads or StoryGraph? Drop your CSV. The app figures out which one it is and does the rest. Any CSV with similar columns (author, publisher, rating, etc.) also imports.

Pick which book you want to read and in which mode: normal or immersive (PRO).

When you end the session, you know how much you've read and at what pace. If the app closes or crashes, the time isn't lost.

  • Normal mode: timer and collapsible minibar
  • Immersive mode: full-screen cover, no distractions
  • Optional ambient sounds (rain, forest, fireplace…)
  • Control from the notification, with the phone locked
  • Both timers are reachable from the counter button at the top
Monthly heatmap

How you read, in detail.

Which month did you read the most? Which day of the month? What time of day do you read most? Lecturameter tells you!

  • Heatmap by hours and by months
  • Month-by-month comparison with charts
  • Yearly wrapped with genres, streaks and authors
  • Complete history of every session with its own stats

Patch notes v3.8

The latest additions to Lecturameter.

New

  • Change the format of a book, comic, manga or audiobook after adding it, without losing sessions, notes or stats.
  • Several notes and quotes when you finish a session, each one separate.
  • If you leave a session without saving, it is kept as a draft and you can recover it the next time you save one.
  • Stats: donut with what you read by format and a format filter to see each type separately.
  • Audiobook challenges (hours listened and audiobooks finished) and Bingo with audiobooks: 1 hour of listening counts as 30 pages.
  • Pagi debuts 7 animated seasonal outfits that work with any theme, 9 new skins (Bard, Night Thief, Vampire Count, Submarine Captain, Ink, Origami, Night Reader, Knight-errant and Retro Astronaut) and its own tap animation with each one. There is also a secret skin hidden in the app: tap around the main screen to find it.
  • Pagi has its own section in Settings: automatic season, seasonal outfits out of season, and skins.
  • App icons for Pro: pick yours in Settings, with Halloween, Christmas and New Year versions. If you turn on automatic seasonal change, the icon changes on its dates and then goes back to yours. It is off by default.
  • On Android, if you tried Pro, you also get one of the Pro icons as a gift.
  • Sync your progress with your e-reader through KOSync (KOReader and compatible ones), with a step by step wizard.
  • The app is now in Arabic, Hebrew, Persian and Urdu, with a right-to-left interface. You can also pick them as the book language when adding one by hand.
  • New Pro timer sounds, with a new category, Cozy.

Fixes

  • Better genre selection for every kind of book.
  • Some stats colors changed to tell each data point apart better.
  • If an e-reader book has no title, a readable name is shown instead of a code, and the wizard warns you if no progress arrives with your user.
  • Bingo is now translated in every language.
  • All languages reviewed: texts that showed up in English or Spanish now appear in your language.
  • Backups saved on your phone no longer end up empty if saving fails.
  • Changing a book's status no longer erases the dates of earlier reads.
  • The monthly recap also counts finished books with no sessions.

Lecturameter on iPhone and Android

The iPhone version has the same main features as Android: library, reading timer, statistics, challenges, bingo, Pagi and the visual themes. These are the differences.

  • Goodreads (CSV): goodreads.com > My Books > Import and export > Export Library.
  • StoryGraph (CSV): app.thestorygraph.com > Manage account > Import/Export > Export STG Library. The CSV arrives by email.

Absolutely. Your data is stored only on your phone. Your library never leaves your device. The app sends anonymous usage statistics and crash reports, which you can turn off in Settings. Also, if a search finds nothing, that text or ISBN is kept, with no identifier, so the missing works can be added. Details in the privacy policy. If you enable Google Drive backup, only you have access to those files.
No. The app is free with an optional one-time Pro purchase.
Almost everything works offline. You only need a connection to search for new books and to upload Google Drive backups.
Yes: you can download it now from the App Store.
Yes. There's a free 7-day trial of Pro features, no card required. On iPhone it is a free App Store in-app purchase, tied to your Apple ID. On Android, at the end of the trial, even if you don't buy Pro, you get a free Pro theme of your choice.
It depends on where you bought it. If you bought it on Google Play and you switch to another Android with the same Google account, install Lecturameter and tap Restore purchase in Settings. If you bought it on the App Store and you switch to another iPhone with the same Apple ID, same thing: install and tap Restore purchase. For now, Pro does not move between Android and iPhone: each purchase stays on its platform. lm-… codes can only be redeemed on Android. More details in How to activate Pro.
Between Android and iPhone, not for now: each purchase stays on its platform. We are looking into whether it can be done somehow. Between two phones on the same platform, yes: use Restore purchase with your Google account or Apple ID.
