Read full description

Turn reading into a daily habit you can see. BookWorm tracks every book, ebook and audiobook, counts pages and listening time toward one daily goal, and keeps your streak alive. Every feature is free. BookWorm is a warm, hand built reading tracker for people who love books and want to actually finish them. No feed, no noise, no ads. Just your library, your progress, and a friendly bookworm cheering you on. WHY READERS FINISH MORE BOOKS • Track any format. Physical books and ebooks by page, audiobooks by hours and minutes. • One daily goal for all of it. Pages and listening time count toward the same target. • Reading streaks, so there is a reason to open a book today. • A calendar that fills in as you read, until your year tells a story. • Real stats: books finished, pages read, hours listened, days read, and your best streak ever. • Your most read genres and a format breakdown, so you learn how you actually read. EFFORTLESS BY DESIGN • Add a book in seconds. Search by title, or scan its barcode with your camera. • Covers, page counts and audiobook length estimates are filled in for you. • Home Screen and Lock Screen widgets show what you are reading at a glance. • iCloud sync keeps your library on every iPhone you own, in your own private iCloud. • Nine languages, switchable instantly with no restart. • Re-read a favourite and BookWorm keeps the earlier read in your history. • Finished a book months ago? Add it with its dates and your calendar fills in behind you. IT FEELS LIKE SOMETHING Saving your progress turns a page. Buttons click, switches flip, and finishing a book has a small celebration you can feel in your hand. And because so many readers here are listening rather than turning pages, BookWorm's sounds can never duck or interrupt your audiobook. Sound and haptics each have their own switch. MAKE IT YOURS Four looks, one tap apart. System follows your phone. Light is warm and creamy. Dark is easy on the eyes at night. And Retro dresses the whole app in a 70s sunset palette of teal, mustard and burnt orange, with chunky outlines and monospaced type. Add your own genres, set the goal that suits your week, and pick the look you like. YOURS, AND PRIVATE Your library lives on your device and in your own iCloud, where the developer cannot read it. There is no account, no sign up, no email address. BookWorm collects a small amount of pseudonymous usage data to fix problems and decide what to build next, never your book titles, your name, or what you type into search. FREE, WITH A TIP JAR IF YOU LIKE IT Every feature is free. No paywall, no locked screens, no subscription, no ads. If BookWorm earns its place on your Home Screen, an optional tip supports one independent developer. That is the whole business model. Start your next chapter today.
