Polygloss vs Erudity

Polygloss helps you to learn a language outside the classroom by turning your world into a textbook. Users can point their camera at objects or places and the app will translate it into the desired language. For example, point your camera at your laptop, and the app will tell you how to say it in French (l'ordinateur portable)! Save these translations to build your own personalised glossary of language cards. The app currently supports translations from English to French, Spanish, Italian, German and Portuguese.

Ever said "I've always wanted to learn that" and never got around to it? Type it into Erudity, and a few seconds later it's a course: one you can actually get through, five minutes at a time. Learn anything, actually anything. Free to browse. Open the app and start reading, no account needed. Hundreds of ready-made subjects are waiting on the shelf, from hieroglyphs to emoji, from the physics of espresso to the history of the Silk Road. The things you always meant to learn. Everyone carries a list. How wine tasting really works. Why placebos do anything at all. What the Fed does all day. Starting always felt like a project: find a decent course, commit your evenings, hope the momentum holds. Here, starting is quicker than choosing what to watch tonight, and the first five minutes already count. Made to be finished. Every subject is built from small topics, each one a deck of swipeable cards you can finish in a single sitting. Choose Beginner, Intermediate or Expert and the cards meet you where you are, so you're always discovering something new instead of re-reading what you already know. Every card hides a longer story. When one catches you, tap Deep Dive and read the full explanation behind it: the history, the mechanism, the part most summaries skip. Progress, quietly kept. A free account saves the cards worth remembering, lets you page back through everything you've read, and marks milestones for how far your curiosity has wandered. Make it yours with Premium. Name any subject and get a custom course built for you, at your level. Skip past the topics you already know, and open every Deep Dive in the library. In your language. Erudity speaks English, Spanish, German, French, Portuguese, Russian, Japanese and Simplified Chinese. Pick a subject. See how deep the rabbit hole goes. The world is your syllabus. Erudity is free to browse. A Premium subscription unlocks custom subjects, Deep Dives and topic skipping. For new users, the annual plan starts with a 7-day free trial, which converts to a paid subscription unless cancelled. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel the subscription anytime in your App Store account settings.
