If you need a dictionary and translator that works anywhere — with or without internet — Dictionary Translator 30+ is the app to have on your iPhone or iPad. Supporting 30+ languages with offline access, camera translation, and a built-in learning system, it goes far beyond a simple lookup tool.
With a 4.6-star rating on the App Store, it is one of the highest-rated dictionary apps for iOS.
Dictionary Translator 30+ is an offline-first dictionary and translation app for iPhone, iPad, and Mac. It covers everything from instant word lookup and sentence translation to camera-based OCR translation and real-time voice conversation between two people.
What makes it stand out is the combination of a proper offline dictionary — with definitions, synonyms, antonyms, and thesaurus — layered on top of a full language learning system. You are not just looking up words; you are building vocabulary with spaced repetition, streaks, quizzes, and daily prompts.
The core of the app is a full offline dictionary covering 30+ languages — no internet required. Every entry includes definitions, synonyms, antonyms, and thesaurus data so you can understand words deeply, not just translate them superficially.
Supported languages include Arabic, Bangla, Bulgarian, Chinese, Croatian, Czech, Dutch, Filipino, Finnish, French, German, Greek, Gujarati, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Malay, Marathi, Portuguese, Russian, Serbian, Spanish, Swedish, Tamil, Thai, Turkish, Urdu, Vietnamese, and more.
Point your iPhone camera at any text — a restaurant menu, a street sign, a product label — and the app translates it instantly using OCR (optical character recognition). No typing needed. This is especially useful while travelling or reading foreign-language documents.
The app includes a real-time conversation mode where two people can speak in different languages and hear each other's translations aloud. It is the closest thing to a live interpreter in your pocket — ideal for travel, business meetings, or international conversations.
Learning a language requires repetition done at the right time. Dictionary Translator 30+ uses spaced repetition (SRS) to schedule flashcard reviews at optimal intervals — so you review words just before you would forget them. This approach is backed by decades of memory research and dramatically improves long-term retention.
A daily streak system keeps you consistent, and a progress dashboard lets you see exactly how your vocabulary is growing over time. These features turn language learning from a chore into a habit.
Every day the app surfaces a new word and phrase to expand your vocabulary passively. Combined with home screen and lock screen widgets, you can absorb new vocabulary even before you open the app.
Students preparing for standardized English exams will find relevant vocabulary support. The app helps build the kind of academic and professional vocabulary tested in IELTS, TOEFL, and SAT, integrated naturally into your daily learning routine.
Bookmarks and history stay synchronized across your iPhone and iPad via iCloud, so you can pick up exactly where you left off on any device.
The app runs natively on iPhone, iPad, and Mac (Apple Silicon) and also supports Apple Vision Pro — making it one of the most versatile dictionary apps in the App Store.
Whether you are a serious language learner or just need a reliable translator for your next trip, Dictionary Translator 30+ is the most complete offline dictionary and translator available for iPhone and iPad.
