Doomersion (formerly Doomlingo) lets you watch short videos in your target language that are exactly matched to your level, and then as you scroll they get a little harder so you learn! That way you can learn languages by immersion, which is how people actually learn!
Scanji
Read full descriptionHide full description
Read the Japanese in front of you - and actually remember it. Scanji turns a photo of Japanese text into readings, dictionary definitions, and real study material, entirely on your device. Point your camera at a sign, a menu, a manga panel, or a textbook page, and Scanji reads it - including vertical text, which most tools miss. SCAN & READ • Snap a photo (or pick one from your library) - no live camera gimmicks, just accurate results from one still image. • Handles both horizontal and vertical Japanese text. • Tap any word for its furigana reading and dictionary definition, pulled from a full offline Japanese-English dictionary. • Optical zoom on the capture screen for small print. • Quiet capture mode - no shutter sound, ideal for libraries, trains, and other quiet spaces. • Works completely offline. No internet required to scan or look anything up. SAVE WHAT YOU LEARN • Every scan and every word you look up is saved automatically. • Star favorites to keep them handy. STUDY - TURN READING INTO VOCABULARY Most translation apps hand you an English sentence and move on. Scanji is built for learners: • Spaced-repetition study (SRS) - review right before you'd forget. • Quiz mode (fast, multiple-choice) or Review mode (Anki-style: reveal, then rate yourself). • Study your own scans, shown right over the photo you took. • JLPT kanji decks, N5 through N1. • Built-in vocabulary decks - common verbs, adjectives, nouns, and adverbs, ranked by real-world frequency. • Progress tracking - a study-activity heatmap, retention stats, and JLPT mastery tracking. • Export your saved words as a spreadsheet or an Anki-importable file. PRIVATE BY DESIGN Everything runs on your device. No account, no sign-up, no cloud sync of your scans, no ads, no tracking. Your reading stays on your phone. Free to scan, read, and build your word history - forever. Scanji Pro unlocks the full study suite (SRS, quizzes, review, JLPT & vocab decks, stats, export). Try Pro free for 14 days. Scan. Understand. Remember. That's Scanji. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Doomersion at none against Scanji's 2. Doomersion also leads on update cadence (every 2 weeks vs every 5 weeks) and iOS requirement (15.5 vs 17.0). On price, ads and device support there is nothing between them.
