Hi everyone! I’m the maker of Principle Keeper, a free Android app for keeping your own trading rules close at hand. You can save short principles, organize them into collections, and have your phone read all your rules or just the ones you select. Choose a repeat interval to listen as you prepare for a session. There’s also a Take a Moment screen with a breathing animation and gentle music. If you want an additional reminder, you can enable rules to appear after unlocking your phone; this optional feature requires Android permissions. The app has no ads and supports English and Korean. A simple place to start: save one rule you want to revisit and play it aloud. If you try it, I’d love to hear what felt useful or confusing, especially when saving and playing your first rule.
