Lupa is a reader's lens. Point your camera at a page, tap any word, and see the definition in under two seconds. No typing. No switching apps. No losing your place. Built for people who read on paper — and want to stay there. KEY FEATURES • Tap-to-define: tap any word on a physical page, get the definition instantly. • Pinch to zoom: get closer to small print without lifting the book. • Works on anything you read: paper books, Kindle, magazines, your laptop screen, even another phone — Lupa just needs a camera and a word. • Drag to select: select a whole phrase and get a nuanced AI-powered reading. • Voice selection: hold the screen, say a word, and Lupa picks it out of the page for you. • Voice Search widget: tap on the Lock Screen, the app opens listening (Premium). • Today's Word widget: a word from your Glossary on your Home Screen each morning, with definition and a tap-to-launch camera shortcut. • Word pronunciation: hear how any word sounds. • History & favorites: every word you look up is saved. Star the ones worth remembering. • 2-second access: open Lupa instantly from the Action Button, Control Center, Lock Screen, or Home Screen widget. • Cloud sync: favorites and history follow you across devices when you sign in. DESIGNED FOR READING Lupa is built around a simple idea: reading flow is fragile, and looking up a word shouldn't break it. The camera-to-definition path is engineered to be faster than reaching for a physical dictionary or switching to a translation app. You keep your book in your hands. You keep your place. You keep going. PREMIUM Unlimited AI translations, voice selection, pronunciation, unlimited favorites and history, and the ability to save a snapshot of the page with each lookup. • 7-day free trial for new subscribers • $4.99 / month or $34.99 / year • Cancel anytime PRIVACY Your lookups live on your device by default. When you sign in, they sync across your devices through our own servers — never sold, never shared, never used to train third-party models. Voice audio is transcribed and discarded immediately. Lupa works best in good light, on flat pages, with the camera pointed straight down. The built-in help covers everything you need to know to get the sharpest possible results. Made with care by a small team in Europe. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
