Naves Topical Bible contains 11,600 of the most frequent but however most difficult to find terms, expressions and idioms used in the Bible with clearly understandable definitions, everywhere off-line, without internet connection.
This app is very user-friendly, as it offers an easy search function, a list of all contents from A to Z and a random-feature, which can be useful for students of Christian theology, to run through randomized terms during some spare minutes.
The screen is visually clear and offers a detailed but still understandable explanation.
You can determine some terms as your favourites and collect them seperately. This feature can be managed easily.
If there are terms, expressions or idioms which you would like to add, you can create new categories and add this term in the respective category, so that you can look it up, whenever you want.
Thanks to the unlimited ability of adding new words, you can create and customize your own little sub-dictionary (by various subjects, etc).
