One of my favorite things about Crossway, publisher of the English Standard Version of the Bible, is how they make their products readily available for free.
They recently published their ESV iPhone app. It’s awesome. Clean. Fast. Free.
Did I mention free?
They have also made the entire ESV bible available for free on their website.
I contacted Crossway about the app and asked if they are working on one for their Study Bible. Their answer: “coming soon.”
