We have received feedback from people with ADHD that thanks to Bionic Reading® they immediately understood the content of various texts the first time they read them, which was impossible without Bionic Reading®. COMMENTS AND FEEDBACK. Jessica: “Having ADHD and processing issues means that I read very slow because my brain can’t focus on the words enough to both read them and process what they mean at a decent pace. Using Bionic Reading® has allowed me to feel functional and productive when I’m reading something lengthy – it’s such a GAME CHANGER!” Lisa: “I have not read fiction for 20 years. I read what I have to read. It almost hurts my brain to read regular type. But now I will be reading fiction again! Bionic Reading® works for me and I can read 2–3 times faster! AMAZING! This is a LIFE CHANGER! Thank You!” Patrick: “OK, Bionic Reading® is the real deal. I already read quickly and this doubled it.” Reaction from Daniel: “Holy smokes you’re not kidding!” Carla: “WOW! I could read quickly and fluently using Bionic Reading®. Doing this helped me understand the context of the paragraph much better than when I have to squint and focus on each word, which tires me out and I lose focus. Bionic Reading® is brilliant!” Nestor: “Your tool is gorgeous, It’s helping me a lot. My sight is reduced because one of my transplanted corneas has become opaque and Bionic Reading® is helping me a lot to read easier and comprehend faster.” TYPOGRAPHY. DESIGN. SWITZERLAND.

Reading is better together. BookSync turns any book into a shared experience: start a room, invite people, and read at the same time without losing your own pace. READ TOGETHER, YOUR WAY Create a room for any book in your library and invite friends with a link or QR code. Everyone's progress shows up on one shared bar, so you can see who's a chapter ahead and who's stopped to reread a page. Follow whoever's leading, or read at your own speed, the lead can be handed off mid-session, so no one has to wait on one person. ONE LIBRARY, EVERY FORMAT Bring your own books. BookSync opens PDF, EPUB, MOBI, AZW/AZW3, TXT, and Markdown files, all in one clean library, no conversion required. A READER BUILT FOR LONG SESSIONS - Day, sepia, and night themes that recolor the whole page, not just the background - Adjustable type built on a variable font, so every weight is available, not just a few presets - Highlight passages in named colors, add notes (even in voice), and drop bookmarks - Full-text search within a book - Smooth text selection and a selection toolbar for quick copying and highlighting START IN SECONDS There's no email, password, or account screen. Open the app, pick a name so your group knows who you are, and start reading. Your device already holds a private account behind the scenes, nothing to set up, nothing to remember. YOUR DATA, YOUR CALL Delete your library or your entire account at any time, and watch it actually happen, BookSync shows real erasure progress instead of a spinner and a promise. Lost your device? Recover your identity with a simple code. BookSync is for book clubs, couples reading together, classrooms, or two friends who just started the same novel and want to talk about it as they go.
