Principle Keeper

Principle Keeper is a free, ad-free Android app for keeping your own trading rules close at hand. Save short principles, organize them into collections, and review them with repeat text-to-speech playback. Listen to all your principles, a collection, or selected rules.

An optional feature displays your rules after unlocking your phone, with the required Android permission. A separate breathing screen with music provides a place to pause.

I built Principle Keeper to make it easier to revisit the rules I had already written for myself. Start by saving one rule and listening to it. The Android download is available through Google Play on our website.
