Turn the words you actually encounter into vocabulary you never forget. G2G is a language-learning app built around a simple idea: the best words to learn are the ones you meet in real life. See a word on a sign, in an article, or in a message? Capture it in seconds and let G2G do the rest. CAPTURE ANY WORD, ANYWHERE • Snap a photo — on-device text recognition lets you tap the exact word you want. Your photos never leave your device. • Type it in, or save words straight from your browser with the G2G Chrome extension. INSTANT AI-POWERED CARDS Every word you save is automatically enriched with a clear definition, phonetic pronunciation, and natural example sentences — so you understand not just what a word means, but how it's actually used. REMEMBER IT FOR GOOD G2G schedules your reviews with a proven spaced-repetition algorithm (SM-2). Rate each card Again, Hard, Good, or Easy, and G2G shows it again at exactly the right moment to move it into long-term memory. LEARNING BUILT FROM YOUR OWN WORDS • A fresh daily article, generated around the words you've saved, so you meet them again in context — with audio narration. • A weekly podcast that turns your week's words into a short, natural episode you can listen to on the go. STAY ON TRACK • A home-screen widget shows your next card and how many are due. • Optional daily reminders at the time you choose. Whether you're studying Spanish, French, German, Japanese, or any of the languages G2G supports, it fits the way you already run into new words — and makes sure they stick. Start capturing. Get to great.

Most statistics sound wrong at first. In a room of 23 people, the odds of a shared birthday are already even. On a game show with three doors, switching after the host opens one doubles your chance of winning. A poll of 1,000 strangers can read a whole country. Math Says Yes is a feed of facts like these, each one explained until the surprise turns into something obvious. Open the app and start scrolling. Every fact is short and sourced, built around a single idea from probability or data. Most come with a quick question that catches your gut before it shows the answer, plus a small chart or a slider you can play with to watch the number move. What's inside: - A scrolling feed of counterintuitive statistics, from the birthday paradox to why tiny samples lie - Quick-check questions tuned to the exact intuition people get wrong - A daily challenge of five questions, so you can find out whether you beat your own guessing - Search and topics for digging into probability, sampling, averages, or plain randomness - Saved facts and a "learned" marker to track what has actually stuck - A glossary that explains the jargon in one paragraph instead of one textbook It costs nothing to read and needs no signup to start. Sign in only if you want to sync saved facts and progress across devices or build a streak. Made for the people who liked statistics in theory but never quite trusted it, and for anyone who enjoys being pleasantly wrong about numbers.
