Jisoku — Japanese, made effortless. Hi there! Jisoku is a Japanese dictionary that fits in your pocket and works anywhere: on the train, on a flight, or deep in a basement with zero bars. Whether you're learning your very first hiragana or polishing up for JLPT N1, we're here to make every lookup quick and every word stick. LOOK UP ANYTHING, ANYWHERE Type in English, Japanese, or romaji, and Jisoku figures out what you mean. All 200,000+ words and 13,000+ kanji live right on your device, so you never have to wait for a signal. POINT YOUR CAMERA, READ IT LIVE Aim at a sign, a menu, or a train timetable and watch the meanings appear as you go. Prefer a photo? Snap one and tap any word on it. Everything is read on your device, and your photos never leave your phone. TYPE IT THE WAY YOU HEAR IT 食べて, 行った, 食べました: search the way people actually talk. Jisoku finds the dictionary form for you and tells you which conjugation you typed. SOUND NATURAL Pitch accent graphs show how every word rises and falls, so 箸 (chopsticks) and 橋 (bridge) never trip you up again. FALL IN LOVE WITH KANJI Watch brush-style stroke order animations and step through each stroke at your own pace. Can't type a kanji? Find it by its radicals, or simply draw it. FIND JUST THE RIGHT WORD Word Finder lets you stack filters like part of speech, pitch pattern, and how common a word is, so you can explore the dictionary your way. MAKE IT STICK Turn any word or kanji into a flashcard and review it in short spaced-repetition sessions. Keep your streak going, fill up your stamp book, and enjoy a little celebration every time you finish. Gentle reminders help you keep showing up. MAKE IT YOURS Add your own notes to words and kanji (and search them later), save your favorites, and say hello to the Word & Kanji of the Day widget on your Home Screen. Everything syncs across your Apple devices with iCloud. No accounts. No sign-ups. Just you and Japanese. がんばって!

Every other app lets AI teach your child. AIPrentice flips it: your child teaches the AI. Hatch a clueless dinosaur that can't tell a cat from a dog. Your child is its teacher - drawing examples, naming them, feeding its tiny brain. Then quiz it! Sometimes it answers with hilarious confidence and gets it completely wrong. That's not a bug. That's the lesson. ONE EGG A DAY, FOR YEARS - A new egg hatches every day with one small, clear thing to do - Over 1200 handmade levels on 24 islands - Collect eggshells: every 50 levels hatches a brand new dragon - Miss a day and nothing is lost: skipped eggs wait in the nest - Grown-ups choose the pace: 1, 3 or 5 levels a day, or no limit - After all 1200, the Endless Sea begins, so the levels never run out EVERY LEVEL TEACHES ONE IDEA ABOUT AI - Draw along a pencil, teach the same thing a few times, then quiz it - Tell two look-alikes apart. Teach one drawing and see why one is never enough - Draw it huge, tiny, tilted or upside down and see what it still knows - Find the drawing filed under the wrong name, throw it out, watch it get smarter - Later on, your child decides what to teach. Their ideas never run out MY DRAWING BOOK - Every drawing your child makes is kept - taught, quizzed, traced or redrawn - in a book to flip through - The story of each thing: the cat from the very first drawing to today's - A drawing coach on the cover: what your child drew this week, where they got braver, one idea for next time. Only about progress - Tidy the book: drag drawings into a new order, or throw one away. What the pet remembers is untouched - Draw it again: an old drawing fades in as a hint, then before and after sit side by side MORE TO DO - Talk to it: teach it words out loud; it talks back using only what you taught it - Ask Dr. Dino: a friendly dino teacher answers questions in simple words, on device - Make it a movie: the book becomes a film with piano music, narrated by the pet. Swipe to pick drawings, make long films, keep them in My Movies, up to 4K. Same-thing drawings play as a flipbook, so your child's cats move - Memory Backpack: see every drawing it remembers, and take memories away. The drawing stays in the book - It remembers you: a little diary of things you did together - Pick up English: teach in Chinese and it shows and says the English too WHAT KIDS ACTUALLY LEARN - AI is taught with data - it only knows what YOU show it - Too few examples means silly mistakes. More examples means a smarter pet - AI can be confidently wrong, which is why you should always double-check it - When it guesses, it shows WHICH memory it thought of, and admits what it never learned - Take memories away and it forgets, even shrinks - the data IS the brain - It coaches you back, and warns you the moment two things look too much alike PARENTS CAN RELAX - On device by design. Nothing is uploaded automatically - a picture leaves only if you, the grown-up, share it - Speech is recognized on device. Recordings are never saved or uploaded - Saving films to Photos stays off until a grown-up turns it on once. The app can only add, never read - No ads, no accounts, no data collected, no tracking (Made for Kids). Works offline - Everything leaving the child's flow sits behind a grown-ups-only gate: sharing, backup, camera, history, pace, reset, tip jar - Camera and photos are off until a parent turns them on. Photos become outlines on device; originals are never kept A NOTE ON "ASK DR. DINO" Needs the on-device intelligence of newer iPhone and iPad on the latest iOS; everything else works the same anywhere. Dr. Dino is labeled as an AI that can make mistakes, keeps to child-friendly topics, and if a child raises something serious it always says: talk to a trusted grown-up now. AIPrentice is free. If your family wants to support development, there is a small tip jar in the parents area. It unlocks nothing: everything is free. Raise an AI. Understand the future.
