About this app
Booktionary lets you look up a word without losing your pace. Hold the phone over the page, put the centre ring on the word, and hold steady for about a second. The definition shows up. Swipe it away and carry on reading. Offline The dictionaries are inside the app, so there's nothing to load and nothing to wait for. No network, no account, no sign-in. English and French Over 1.9 million entries. Inflected forms go to the entry you'd actually look up: "mangeaient" gives "manger", "running" gives "run". You pick the book's language when you open the app, and the back arrow shows which one is active. Recognition Tuned for a book held the way you'd normally hold it, not flat on a table. A green highlight sweeps across the word as it reads, so you can see what it picked up and when it's done. Privacy No analytics, no tracking, no accounts, no network requests. Camera frames are processed on the phone and thrown away. Nothing is saved, nothing is sent. Requirements iOS 17. iPhone only.
Latest release
What’s New
Choosing the book language moved to the opening screen. The camera screen's back arrow now carries the language with it — "‹ EN" or "‹ FR" — so you can always see which dictionary is active, and tapping it takes you where you change it. The EN/FR badge is no longer a hidden switch you could nudge by accident.
