Todaii is a Japanese reading and listening application for iOS and Android developed by Mobile Learning. It delivers real Japanese-language news articles graded by difficulty from JLPT N5 through N1, with an inline tap-to-look-up dictionary, listening exercises, and a built-in JLPT mock test module.
In-Depth Explanation
Platform: iOS and Android (Google Play: `mobi.eup.jpnews`). 1,000,000+ downloads on Android; 4.3 stars with over 31,000 ratings. Free with premium subscription available. Developed by Mobile Learning; the same Todaii news-reading infrastructure also powers the news section within Mazii.
Todaii’s primary differentiator is its use of authentic Japanese news content rather than purpose-written learner texts. Articles are drawn from real news sources and tagged by JLPT difficulty level, allowing learners to select reading material calibrated to their current proficiency. The inline dictionary enables immediate tap-to-lookup for unknown words without leaving the reading interface.
Graded Reading
Articles span JLPT N5 through N1, making the app usable across a wide proficiency range. N5 and N4 articles use simpler vocabulary and shorter sentences. N2 and N1 content reflects authentic journalistic writing with dense vocabulary and complex grammar structures. Todaii includes 356 labelled JLPT N5–N1 reading practice exercises alongside the live news feed.
Listening and Speaking
Todaii includes listening exercises with native-speaker audio and a speaking practice module using AI-powered pronunciation feedback. 72 conversational dialogue exercises are included for listening comprehension.
JLPT Mock Tests
A built-in mock test module provides JLPT-format practice across vocabulary, grammar, reading, and listening sections, offering exam simulation within the same application used for daily reading practice.
History
Todaii is part of the Language Skills Studio / Mobile Learning family of Japanese-learning apps — the same developer network behind HeyJapan and Migii JLPT. The news-reading platform was originally developed as a standalone resource and has since been integrated into Mazii’s interface as well. Todaii’s graded real-news approach predates the more recent wave of AI-generated graded readers, making it one of the earlier mobile applications to apply authentic news content to JLPT-level scaffolded reading practice.
Common Misconceptions
“Reading graded news articles is enough to pass the JLPT.”
Todaii is strongest as a reading and listening input tool and less comprehensive as a standalone JLPT preparation system. Grammar structure study, vocabulary drilling, and timed full-exam practice from dedicated preparation resources are important complements.
“N5-level articles are written by teachers — they are simplified versions of real news.”
Todaii sources its articles from real Japanese news outlets and applies difficulty tagging rather than rewriting. N5 articles may be shorter or drawn from simpler topic areas, but the underlying language is authentic.
Social Media Sentiment
Todaii is well-regarded on r/LearnJapanese as one of the more practical tools for the intermediate plateau — the period where learners have passed N5–N4 content but are not yet fluent enough for unscaffolded native media. The tap-to-lookup dictionary is consistently cited as the key feature enabling learners to read above their current level. Some users find the ad-supported free tier intrusive and recommend the premium subscription. The listening and speaking modules receive less discussion than the reading features. No significant controversy surrounds the app.

Summary: Primary source for all app-specific details including developer, feature set (graded news reading N5–N1, inline dictionary, 356 reading exercises, 72 conversational exercises, JLPT mock tests, AI speaking practice), and download and rating figures. Verified May 2026.
- Krashen, S. D. (1982). Principles and Practice in Second Language Acquisition. Pergamon Press.
Summary: Articulates the comprehensible input hypothesis — the principle that acquisition occurs when learners are exposed to language slightly above their current level (i+1); Todaii’s graded news articles, combined with inline lookup support, operationalize this principle by making authentic Japanese text accessible across proficiency levels.
- Day, R. R., & Bamford, J. (1998). Extensive Reading in the Second Language Classroom. Cambridge University Press.
Summary: Establishes the research basis for extensive reading as a vocabulary and fluency development strategy; Todaii’s daily news reading model — reading large amounts of comprehensible text for meaning — is a direct application of extensive reading principles in a mobile context.
