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

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.
I'm actively working on it right now. You can join the waitlist using the form above or by emailing lecturameter.app@gmail.com.
Yes. There's a free 7-day trial of Pro features, no card required. 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 how you activated it. If you bought it on Google Play (regular purchase or a Play promo code) and you switch to another Android with the same Google account, just install Lecturameter and tap Restore purchase in Settings. If you bought it on the App Store (regular purchase or an App Store promo code) and you switch to another iPhone or iPad with the same Apple ID, same thing: install and tap Restore purchase. To move between Android and iPhone in either direction, whatever the source (Play purchase, App Store, promo, or an lm-… code), use a pairing code: on your current phone, in Lecturameter Settings, Pair device, get a temporary code, enter it on the new device and it activates there too. If you sell or lose the old device, you can revoke it from the same screen. More details in How to activate Pro. Available once Lecturameter for iOS launches.
Yes. With a transfer code generated inside the app, you can move your Pro between phones, even switching from Android to iOS or iOS to Android. You can manage your Pro devices and generate transfer codes from Settings. Available once Lecturameter for iOS launches.
