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.
Short answer
LingoDeer teaches full Japanese curriculum through lessons. Inku teaches vocabulary, kana, and phrases through spaced flashcards.
Intro
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 Inku is 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 native voice acting. Inku's audio is actor-recorded. LingoDeer uses TTS for most content.
- You want a calmer interface. LingoDeer has animations, XP, and streak mechanics. Inku has none.
When LingoDeer is 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.
