Trilinguo
Read full descriptionHide full description
Trilinguo turns any book into a gentle language lesson. Every passage is shown in the original language with translations stacked right beneath it — a sentence or two at a time — so you learn while you read something you actually want to finish. No flashcards. No drills. No streaks to lose. Just a book, in three languages at once. HOW IT WORKS • Bring a book — import your own PDF or EPUB, or open one of a hundred public-domain classics built in. • Read it stacked — the original on top, your practice language beneath, and an optional third language below that. One passage per page, nothing else on screen. • Keep the words — tap any word for an instant lookup and save it to your vocabulary; highlight and annotate as you go. A HUNDRED CLASSICS, READY TO READ Austen, Brontë, Dickens, Conrad, Twain and more — every passage already translated, so the first page opens instantly. Practice languages include Spanish, French, German, Italian, Portuguese, Dutch, Russian, Macedonian, Japanese and Chinese. PRIVATE BY DESIGN No account required. No ads, no analytics, no tracking. Your library, notes and vocabulary stay on your device. Books are sourced from the public domain.

Studying alone is why you stop. Study Tracker turns it into a duel with a friend. TIME IT Start the timer when you sit down. It keeps running if you lock your phone, close the app, or restart it — your session is anchored to a start time, not to the app staying open. A Live Activity keeps the count on your Lock Screen and in the Dynamic Island. Forgot to start it? Add the session manually. DUEL A FRIEND Challenge anyone on your friends list. Each round runs seven days from the day they accept. Win a point for every day you study more than they do, three for winning the week. Your existing sessions count automatically — nothing is logged twice. SEE IT HONESTLY Hours per day, cumulative by hour, where your time actually went by subject. A daily goal, a streak that only counts days you hit it, and a running week total. Overlay a friend's data on your own charts to see the gap. TALK ABOUT IT Comment on each other's sessions. See when a friend is studying right now. Get a notification when they log time or reply to you. MADE FOR REAL COURSEWORK Track subjects separately. Eight accent colours, and the app icon changes to match. EVERYWHERE The web app and the iPhone app are the same account and the same data, live in both. PRIVATE BY DEFAULT You choose whether your progress is private, visible to friends, or public. Report or block anyone. Delete your account and everything in it from inside the app, whenever you want. Free. No ads. No tracking.

Verdict
The clearest difference is in-app purchases: Study Tracker at none against Trilinguo's 2. Study Tracker also leads on update cadence (every 4 days vs every 9 days). On price, ads, device support and iOS requirement there is nothing between them.
