Inku vs LingoDeer
Inku vs LingoDeer for Japanese
LingoDeer is a structured curriculum for Asian languages. Inku is a focused flashcard deck for Japanese. Depth vs focus.
How does Inku compare to LingoDeer?
LingoDeer came out of Korean and Japanese teachers who were frustrated with Duolingo's Asian-language handling. It's the app that most seriously covers Japanese grammar in a lesson format. Inku takes a different approach: flashcards and audio, not lessons.
When is Inku the better pick?
- You want to learn at your own pace, not through lessons. LingoDeer is lesson-based. You go A then B then C. Inku lets you dip in for 10 minutes without committing to a lesson.
- You want audio-supported review. Inku's audio is bundled with each card. LingoDeer uses TTS for most content.
- You want a calmer interface. LingoDeer has animations, XP, and streak mechanics. Inku has none.
When is LingoDeer the better pick?
- You want a full curriculum, not just vocab. LingoDeer covers grammar, reading, listening, and speaking in a progressive course. Inku covers vocab, kana, and phrases.
- You want lessons with explanations. LingoDeer includes in-app grammar explanations. Inku does not teach grammar directly.
