Ready to take your Japanese reading and listening comprehension to the next level? Welcome to Satori Reader. COMPELLING STORIES Read from a growing library of engrossing stories written by native speakers for intermediate students, across genres such as fantasy, slice-of-life, thrillers, documentaries, news, and more. AUDIO Tap any sentence to hear it read aloud by native voice actors (no robots!). ADAPTIVE KANJI USAGE Crack the chicken-and-egg problem of reading kanji with our unique presentation engine, which adjusts the Japanese text to accommodate your actual knowledge. This allows you to challenge yourself for the kanji you should know without being overwhelmed by what you don't. SMART DEFINITIONS Tap any word for a definition. This is more than just an automated lookup. Satori Reader shows the actual sense of each word as it's being used in the sentence. For example, the particle の has many uses: it can indicate possession; it can turn the preceding verb or phrase into a noun; it can stand in for another word; and more. We show you exactly what is happening in every instance of every word. FRIENDLY ANNOTATIONS Gray underlines indicate longer annotations that break down tricky expressions, provide cultural background, or help you to read between the lines. Our editors work hard to anticipate what might be confusing and proactively help you to make sense of things. Good-bye, confusion. Hello, clarity! SPACED REPETITION SYSTEM (SRS) The built-in spaced repetition review system helps you to build your vocabulary. Create review cards instantly as you read. Each card you create takes along a snapshot of the sentence in which you encountered the word, further helping to cement it in your memory. You can even play back the audio of that sentence while reviewing the word! HUMAN FEEDBACK Still confused about something? Just ask in the discussion section below each episode. Our team of friendly human beings is ready to help. Satori Reader is built by a team that cares. Our goal is to bring satori (enlightenment) into your Japanese reading life.

Ever notice that kana apps always split things in two? Hiragana now. Katakana… someday. (And then you never really learn a few of the katakana.) And why are we learning the stroke order as beginners? Are we going to paint someone a letter? No! We need to know how to type on that cool 12-key Japanese フリック入力 flick keyboard! Cyber Kana makes it fun and easy to learn the kana (hiragana and katakana side by side) and get really fast on the Japanese keyboard. Try it now! Be warned: A snarky Japanese-speaking sensei insults you mercilessly while you learn. がんばって! GAME MODE • Jam out to techno music while you race the clock. • Stuck on a kana? Tap "?" and the keyboard itself shows you exactly which keys to press and which way to flick. • Claim your spot on the Worldwide Leaderboard, ranked by Highest Scores and Longest Streaks!

The clearest difference is update cadence: Japanese Keyboard Trainer at every 5 days against Satori Reader's every 3 months. Japanese Keyboard Trainer also leads on rating (5.0 vs 4.8).
