Inku vs Anki
Inku vs Anki for Japanese
Anki is the open-source SRS warhorse. Inku is the opinionated iPhone flashcard app. Power vs polish.
How does Inku compare to Anki?
Anki is the grandparent of spaced-repetition apps. Learners have leaned on it to study Japanese for close to two decades, some all the way to N1. It is also famously bare, which is a feature or a flaw depending on who you ask. Inku is shaped like Anki's younger, more opinionated sibling.
When is Inku the better pick?
- You don't want to build your own deck. Inku ships with 17 unlocked study bundles with audio support. Anki requires you to find (or build) a deck, vet the content, and hope the TTS is passable.
- You want a calm, beautiful daily session. Inku's review session is designed for the calm, quiet 10 minutes before bed. Anki's UI is utilitarian; the cards are whatever you made them look like.
- You want audio support. Inku bundles audio for the main card library. Anki decks vary because many are made by users.
- You want to start today, not set up for a week. Inku works after a 2-minute onboarding. Anki requires finding a deck, installing add-ons, maybe running a custom scheduler. The setup cost is real.
When is Anki the better pick?
- You want complete control over your cards. Anki lets you customize everything: card templates, scheduler, interval modifier, add-ons. If you like tinkering, Anki wins on depth.
- You need to study non-Japanese material. Inku is Japanese-only. Anki handles medical school, law, chess openings, and any other fact-based domain.
- You already have a large deck built. If you have spent 6 months curating your own Anki deck, switching costs are high. Stick with it.
- You need advanced features (occlusion, cloze, LaTeX). Anki's add-on ecosystem supports image occlusion, cloze deletions, MathJax, and a thousand other niche needs. Inku is flashcard-shaped by design.

Inku's favor · Anki's favor · roughly even
The honest take
Anki is a nuclear reactor. It is incredibly powerful and it will happily let you turn it into a shrine. If you enjoy that, stay. Inku is the opposite: a single-purpose tool that does one thing without asking you to configure it. The choice is mostly about whether you want to build a study system or just use one.
Verdict
Use Anki if: you love customization, need multi-domain SRS, or already have a large personal deck. Use Inku if: you want Japanese flashcards with audio support, ready to use, without a weekend of setup.
Most learners do not need Anki's power. If you want to learn Japanese and you want to start today, Inku is the faster path.

Common questions
Can I import my Anki deck into Inku?+
Not yet. Inku ships with a curated deck and there's no import path. If you have a beloved Anki deck, you can keep Anki for that deck and use Inku as a second app.
Does Inku use the same FSRS algorithm as Anki?+
Yes, the underlying scheduler math is FSRS with parameters tuned for Japanese learning. The difference is that Inku hides the scheduler entirely; Anki exposes every dial.
Is the yearly plan worth it over AnkiMobile's one-time price?+
If you value the audio support, the curated deck, and the calmer UI, yes. If you are a power user who will build your own deck anyway, no.
