SRS-based review scheduling
The app uses spaced repetition to schedule vocabulary reviews, recording each word’s learning stage, next review date, and last update time.
Mainichi
Mainichi is a Japanese vocabulary app for iOS and Android with spaced repetition flashcards, short study sessions, and gamified progress tracking.
What Mainichi is
Mainichi is a Japanese vocabulary learning app built around spaced repetition flashcards. It is available on iOS and Android, and its core workflow combines vocabulary study, scheduled reviews, and lightweight game-like progression.
The product page says the app teaches real Japanese vocabulary in short sessions that are designed to take under five minutes a day. It tracks learning progress, uses a level system, and presents learning as a path of unlocking Japan’s prefectures while building vocabulary knowledge.
Core features
Large vocabulary set with session tracking
Mainichi supports over 20,000 Japanese words and organizes learning into short discovery and practice sessions.
Prefecture-based progression
The home page describes a progression model where you unlock all 47 prefectures of Japan while learning vocabulary.
Gamified learning mechanics
The interface includes gamified elements such as points, a leaderboard, dice rolls, and boss fights, all tied to learning activity.
Account and profile support
Users can create accounts with email and password or sign in with Google or Discord, and the app stores a display name and avatar for leaderboard use.
Tiered access controls
Paid plans remove the main daily activity caps and add avatar customization, while the free tier keeps limited daily usage.
Ways people use Mainichi
Daily Japanese study
Learners can use Mainichi for daily vocabulary practice when they want a short study habit instead of long textbook sessions. The app is designed around quick review blocks and lightweight progress tracking.
Spaced-repetition review
Because the app records SRS state and next review dates, it works well for learners who want to revisit words on a schedule instead of randomly re-reading lists.
Motivation through progression
The gamified elements—points, leaderboards, dice rolls, and boss fights—support users who prefer visible progress and small achievement loops while studying.
Mobile-first learning
Users who want to study on mobile can use the app on iOS or Android and sign in with email, Google, or Discord.
Evaluating the app before upgrade
Learners on the free tier can test the app with daily limits before deciding whether the unlimited paid plans are worth upgrading to.
