Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app

Text from the App Store listing.

SlowRead is the book tracker with a bookshelf you will want to show off. Every book you read stands on your own shelf, with its real spine and cover.
Keep your TBR, your reading journal and your reading log in one place, and share your bookshelf on BookTok and Instagram.

YOUR BOOKSHELF

  • Every book stands on the shelf as a spine or as a cover.
  • Photograph your own copy to show its real spine, cover and sprayed edges, or use a photo another reader already shared.
  • Arrange your books by hand, lay them flat in piles and keep a series together.
  • Decorate with plants, candles, lights and more, and pick a theme for the wall and the wood.
  • Share a picture of your bookcase to your Stories on TikTok or Instagram.
  • Get a public profile at slowreadapp.com/@you with the bookcases you choose to show.

BOOK CLUBS

  • Create a club or join one and read the same book together.
  • Talk in a channel for each part of the book, so nobody spoils what comes next.
  • Hide the parts of a message that are spoilers.
  • Vote on the club's next book.

YOUR READING YEAR

  • Monthly and yearly wrap ups: cards to swipe through and share.
  • Your reader type, worked out from the books you finish.
  • A yearly reading challenge, and your year next to the last one.
  • Stats for pages, time and books, your reading speed and your top genres.
  • A reading streak, with past days you can fill in by hand.

TRACKING WITHOUT EFFORT

  • Search millions of books or scan the barcode to add one in seconds.
  • Import your library from Goodreads, The StoryGraph, Bookmory, Fable or Libib.
  • Paperback, ebook and audiobook, even for the same book.
  • Track library loans with the due date and a reminder the day before.
  • Series grouped together, with your progress through each one.
  • Notes, quotes scanned from the page with your camera, and characters with a portrait and their relationships.
  • Half star ratings, rereads and did not finish.

WIDGETS

  • Your bookshelf, what you are reading, your streak, your challenge and a daily quote on your Home Screen and Lock Screen.

READING SESSIONS

  • Start a timed session from any book and log the page where you stop.
  • If you want, block the apps that distract you while you read, with Screen Time.

All features described above require a subscription. A free trial is included, so you can try everything before paying.
