Santa Biblia Reina Valera 1960 is a full-featured free Bible app. If you're looking for a decent Android app to look up passages of the sacred texts of Christianity, this tool is a fine option for all purposes.
Within this app there's both an Old and New Testament for you to read up on, neatly divided into two different sections so you can read through them by clicking on any of the two categories. At the same time, within each of them, there's a complete list of the books divided up so you can read the Bible any way you want and access specific parts without having to search for it exhaustively through passage after passage of the Holy Word.
One of the advantages of Santa Biblia Reina Valera 1960 is that it also includes the book of psalms, along with a handy night mode feature. So you can opt to change your interface to adapt to night reading. In addition, it's up to you to modify the font size to suit your needs. Enjoy learning from the wisdom of the Bible without any issues for your reading, or undue eye strain.
This tool is handy and allows you to read the entire Bible by sliding your finger to move on to the next chapter. That way you won't have to go out and look for readings every time you want to memorize them, instead you can simply bookmark them and easily go back anytime you need to.
