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
