I have a hard time remembering all the Bible verses I should be "hiding in my heart." Finally, I've given up on remembering every verse I want to remember, so I wrote a web app to hold them all: 43 Verses.
The app uses the freely available English Standard Version web service API to retrieve the verse and add it to your list. You can also add tags to your verses to help find them later. Tagging also helps you find other verses of similar topic because other people are tagging verses, too.
Anyway, give it a try.
