Add today's word to your Home Screen or Lock Screen, so a new word is always within reach.

I built Jargon because I wanted to pick up new words in the languages I was learning without opening yet another app with a login screen and a subscription paywall. It's a tiny, private ritual: one word a day, generated just for you, entirely on your device.
