Lock Learn: Passive Learning!

Lock Learn puts a vocabulary word on your lock screen and swaps it out every 10 minutes, all day. You're checking your phone constantly anyway, so you might as well pick something up in the meantime. There are no study sessions, no streaks to maintain, and no extra time required.

How it works:
Add the Lock Learn widget to your lock screen. From that point on, every time you glance at your phone you'll see a different word from your list along with its definition and grammar type. The widget refreshes in the background every 10 minutes without you doing anything.

Build your own word lists:
Lock Learn isn't tied to a preset word bank. You create topics for whatever you're working on: a language you're studying, industry terminology, SAT prep words, culinary terms, anything you want. Every entry includes a definition and a grammar label so you understand how to actually use the word, not just what it means.

Tap to go deeper:
Spot a word you want to explore? Tap the widget and Lock Learn opens directly to that word's topic so you can review, edit, or add related words.

Free to start:
You get up to 20 vocabulary words completely free, with no trial period and no expiration date. If you want more, a small one-time purchase unlocks unlimited words and there's no subscription.
