Eynfel is an acronym: Everything You Need For Effective Language Learning. The name is a promise — not a pile of scattered tools, but one place where every part of learning connects to the next. EVERYTHING • Word sets — flashcards with real context sentences, studied through 7 different modes. • Texts — reading at your level, with a translation for every sentence and comprehension questions. • Sentence sets — work through patterns and structures sentence by sentence until they stick. • Grammar — structures grouped by category, with real examples and exercises tied to the topic. • Dictionary — tap any word and every meaning, word type and example opens. • Media — YouTube videos and podcasts to get used to real speech and different accents. YOU Your level, your interests, your goal — and even your taste. • A learning journey with stops built for your level, so you never have to decide where to start. • Three separate language axes: the language you are learning, your native language, and the interface language. • A daily goal you set yourself, tracked by the app. • Themes, your own colour choice, light and dark mode, and readable typefaces. • The same account on web and mobile — continue on your computer where you left off on your phone. NEED We surface what you need today; the rest stays out of your way. • Today — your day is planned automatically: review, new content and practice, balanced. • Continue — everything you left unfinished, in one place. • Smart review — words you struggle with come back more often, the ones you know less often. • One search box for words, texts, grammar, people and groups. FOR Every step connects to the next — a path, not a pile of exercises. • Every study session turns into points, and points into levels. • Streaks count consecutive days — not breaking one is the best motivation there is. • Badges mark milestones; progress history records exactly where every point came from. • Journey stops unlock as you complete them. EFFECTIVE • AI Partner — practise by chatting in the language you are learning, with corrections as you go. • AI voice call — speak in real time and get over the fear of speaking, with nobody watching. • Writing evaluation — have AI assess what you wrote, point out mistakes and suggest more natural alternatives. • AI content generation — build your own word set, sentence set or text on any topic. • Instant feedback — see the right answer and the reason behind it immediately. LANGUAGE LEARNING Not just drills: real people, real conversations and a real creator economy. • The catalogue is stored in its own language but translated into 33 — understand it all in yours. • Groups, friends, one-to-one messaging and voice calls with real users. • Work with a coach, or become one and share content made for your students. • Build your own content and share it free, sell it, or open it to subscribers. GOOD TO KNOW • Eynfel is for adults aged 18 and over. • Some features use AI (Google Gemini). The app asks for your explicit permission before any of your text is sent, and you can withdraw it at any time in Settings. • Credits are one-off in-app purchases. There is no automatic renewal and no subscription trap. • Community features include messaging and voice calls. Reporting and blocking are built in, and AI responses can be reported too. • Prices include VAT and are always shown in full before you buy anything.

Verdict
The clearest difference is ads: Eynfel at none against Sentence Forge's shown. Eynfel also leads on update cadence (every 3 days vs weekly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
