Inku vs Renshuu
Inku vs Renshuu for Japanese
Renshuu is a powerful, forum-backed Japanese web tool. Inku is a native iPhone app. Flexibility vs polish.
How does Inku compare to Renshuu?
Renshuu is a love letter from a small team of Japanese teachers. It has forums, custom schedules, thousands of user decks, and a depth that only 14 years of iteration can produce. Inku is the opposite: one deck, one opinion, built for the 10-minute phone break.
When is Inku the better pick?
- You want a native iPhone app, not a web app. Inku is SwiftUI native. Renshuu is primarily web-based; the iOS app is lighter than the web.
- You do not want to customize. Renshuu rewards tinkering: custom schedules, custom quiz modes, user decks. Inku gives you one curated deck and one review flow.
- You want audio-supported review. Inku's audio is bundled with each card. Renshuu uses TTS.
When is Renshuu the better pick?
- You want a generous free tier. Renshuu's free tier covers a lot. Inku is subscription-first.
- You like community-built decks. Renshuu has a large library of user-generated Japanese decks.
- You want a forum for questions. Renshuu has an active community. Inku is email-only.

The honest take
Renshuu is the classic power-user Japanese tool. If you want control and community, it is a wonderful and free option. Inku is the opposite: a finished product you just use. The choice is about what you want to do with your 10 minutes a day.
Verdict
Use Renshuu if: you want web-based, free, and customizable. Use Inku if: you want native iPhone with audio support and no setup.
Try Renshuu's free tier first; if the web-first feel doesn't land, Inku is the native alternative.
