Read the book or listen to it. Switch from where you left off. Ask the AI questions about what you're reading. Have it generate images. This isn't a store and it isn't a subscription. If you already own the ebook and the audiobook, however you got them, TomoTomo just works with the files you have. No new library to buy into, no locking your books behind another app's account, no paying Amazon a second time for something you already paid for once. What it does: Reads your own EPUB and PDF files, full screen, nothing in your way Plays your own M4B and MP3 folder audiobooks, with real lock screen controls Pairs books to their audiobooks automatically, or manually if it guesses wrong Highlights the narrated sentence as you read, with word highlighting and a reading window if you want them Finds a passage in the text and jumps your spot to it Lets you highlight and keep notes as you read Asks an AI companion about your book, with spoiler-aware catch-ups Generates illustrations from passages, and custom covers Adjustable font, spacing, and five themes, including true black Playback speed and a sleep timer, because obviously Browses free public-domain books and audiobooks Keeps your files on your device. Reading, listening, page scanning and audio alignment all work without a connection Syncs your position, highlights and stats across your devices using an anonymous account. No email needed unless you choose to sign in No ads, no analytics, no tracking There's also an optional AI companion. Ask questions about the book you're reading, get caught up on the chapters so far, or talk through what just happened. You choose how much of the book it can see: just nearby text, everything up to where you are, or the whole book. Imagine turns a passage you're reading into an illustration, and you can generate a custom cover for any book or audiobook. Nothing is sent until you use one of these, and the app shows you what it will send first. Generated images stay on your device. That's it. No gamification, no login wall, no upsell before you've even started reading, no renting access to books you've already bought. Just your books, staying in sync.

Verdict
The clearest difference is rating: TomoTomo at 5.0 against Leafmark's 4.0. TomoTomo also leads on review sentiment (100% vs 67%) and monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. TomoTomo sells 5 one-off in-app purchases and Leafmark sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
TomoTomo holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: TomoTomo has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of TomoTomo's written reviews are positive against 67% of Leafmark's.
TomoTomo ships an update every 6 days, Leafmark every 5 days. Both last shipped on November 5, 2026.
