From the e-Sword site: e-Sword is a fast and effective way to study the Holy Bible.
e-Sword is feature rich and user friendly with more capabilities than you would expect in a free Bible study app.
The fact that e-Sword is free is just one of the blessings and does not speak of the quality of the app.
Editor’s Note: The e-Sword Bible app makes searching, citing, editing and copying various translations of the Bible quick and easy. All the other available features are a bonus. My favorite is the Douay-Rheims Catholic Bible.
