I don't know how I came up with this app's name, but I know I really needed this app when I was scrolling Twitter and TikTok and kept running into words that took me 15 minutes to decode. Now you can discover new words too and collect them like cards in this beautiful and sensational app that we've built with my friend together. Add GGG widget.  A new word drops on your home screen every day.  Ask any word in app.  Save the ones you like as a card, skip the ones you don't. It's your collection. That's it. No ads, no tracking. Just words. GGG runs on a small annual subscription only — but you get a 3-day free trial to vibe with it first. Payment kicks in after the trial ends and renews automatically unless you cancel at least 24 hours before.
