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.

Verdict
The clearest difference is in-app purchases: G2G at none against CapWords's 7. G2G also leads on rating (5.0 vs 4.7). CapWords's advantage is ratings volume (603 vs 1). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CapWords sells 6 in-app purchases, starting at $4.99 per month. G2G asks for nothing beyond the download.
G2G holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CapWords has 603 ratings behind it against 1, so its average is the more settled of the two.
