Schrödinger’s Box Most apps are designed to absorb time, smooth friction, and reward passivity. They assume you are bored and want to stay that way. Schrödinger’s Box was built as a refusal. Once a day, the app presents a single paradox, ethical dilemma, or thought experiment drawn from philosophy, science, and moral reasoning. You are given limited time. You must choose. There is no neutral option, no skipping, and no undo. When you decide, the question collapses, and the comfort of ambiguity collapses with it. This is not trivia, a quiz, or a game. The decision is the experience. How It Works • Once per day One challenge. No feeds, no binging, no endless scrolling. • Timed You cannot deliberate forever. The clock matters. • Irreversible Once you choose, it’s recorded. Just like real decisions. • Interpretive, not corrective Afterward, you’re shown multiple philosophical perspectives on the choice you made. There is rarely a single “right” answer. What You’ll Encounter Schrödinger’s Box draws from centuries of inquiry into questions that shape how we live: • Identity and persistence over time • Free will and causality • Moral judgment under constraint • Infinity, limits, and paradox • Mind, consciousness, and artificial intelligence These are not abstract puzzles. They are the same questions that quietly structure our assumptions about responsibility, agency, and meaning. Educators have long used dilemmas like these as intellectual icebreakers. They wake people up. They expose hidden intuitions. They reveal disagreement immediately. Schrödinger’s Box brings that experience into a daily, private ritual. What It Is Not • Not self-improvement • Not productivity • Not optimization • Not social media There are no scores, no streak pressure, and no behavioral manipulation. The goal isn’t to make you better. It’s to take thinking seriously. Privacy by Design Your choices are stored only on your device. There are no accounts. No tracking. No data collection. Your philosophical record belongs to you alone. Pro Version A one-time purchase unlocks: • Full access to the archive • Complete choice history • Advanced and harder challenges • Streak and pattern insights No subscriptions. No ads. Lifetime access. Open the box. Face uncertainty. Make a decision.

Tap any word in real Japanese or Chinese — a podcast, a news article, a novel, a website, your own audio file — and get its reading and its meaning instantly, without leaving the page. The dictionaries live inside the app. Every word is worked out on your device, you never have to sign in, and it all works with the plane in the air. Two engines, one Japanese and one Chinese, work out how each word is actually read in the sentence in front of you — furigana and pitch accent for Japanese, pinyin with the real tone changes for Chinese. Traditional and Simplified characters are both first-class. LISTEN Find shows by search, from the trending charts in Japan, Taiwan, and China, or from a hand-picked list for learners. Every episode gets a transcript — either supplied by the show or generated privately on your device — and the whole transcript is tappable while the audio keeps playing, with the current line following along as you listen. Shadowing mode loops a sentence so you can repeat after the speaker, and you can record yourself to compare. READ ANYTHING Browse Japanese and Chinese websites with furigana or pinyin added in place. Paste a link and get the clean article without the clutter. Import your own EPUB, PDF, text, or subtitle files. Scan a printed page with the camera. Books are laid out like books, with proper Japanese and Chinese line-breaking and real chapters. TAP TO UNDERSTAND Two purpose-built engines — one Japanese, one Chinese — work out how each word is actually read in the sentence in front of you, not just what a dictionary lists. Japanese gets furigana, pitch accent, and conjugation breakdowns. Chinese gets pinyin with tone changes applied. Traditional characters are a first-class choice throughout, not an afterthought. LOOK ANYTHING UP Search from Japanese, Chinese, or English. Draw a character you can't type. See stroke-order animations, radical breakdowns, word frequency, and example sentences from real usage. REMEMBER IT Save a word and it keeps the sentence you first met it in, and where it came from, so you can jump straight back. Spaced repetition returns it just before you'd forget. A home-screen and lock-screen widget keeps a word in front of you, and an optional once-a-day reminder tells you when reviews are ready. Export to Anki at any time. ON IPHONE AND IPAD Toku Reader is built for both. On iPad the transcript, the reader, the dictionary and your word list use the full screen rather than a stretched phone layout. OFFLINE, AND NO ACCOUNT The dictionaries ship inside the app and every word is worked out on your device, with no internet connection. You never have to sign in. Your library is copied to your own iCloud so it follows you between your iPhone and iPad, and you can switch that off, and delete the copy, in Settings. The only text that ever leaves your device is the sentence you ask the AI about, and only after you switch that feature on. WHAT'S FREE Listening, reading, browsing, shadowing, and reviewing are free and unlimited. Word lookups are free up to 15 a day. Toku Premium removes that limit, monthly or yearly. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel any time in Settings → Subscriptions.
