The one app I cant live without

Ive had this app for 6 years now (!) and its the one app that I cant live without. The translated reference sources are varied, insightful and clear, and provide variety of perspectives. The sources range from modern interpretation (with multi language support) to classical versions in Chinese (character and phonetic systems). The UI is clear and highly functional, and is well maintained by the developer with regular updates. This one app has gradually replaced every single book I had on the subject. Highly recommended.
