Daily Bible Study: Protos
Prayer, Devotional & Reading
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Three deep Bible studies a week, every Mon, Wed, and Fri. Plus commentary, sermon notes, and 74 in-depth guides. For the people who teach, lead, or want answers.
Study the Bible with the context most apps leave out.
For Christians who lead small groups, teach Sunday school, prep sermons, or just want a real answer when a friend asks, "What does this verse mean?"
Protos is the Bible study app that gives you trusted commentary, a built-in dictionary, sermon notes, three deep study sessions a week, and a library of 74 in-depth guides covering the doctrines most apps skip. Christology (who Jesus is), soteriology (what salvation means), ecclesiology (what the church is for), and the rest of systematic theology, all explained in plain English.
WHAT MAKES PROTOS DIFFERENT
Most Bible apps give you the text and call it a day. Protos gives you the full picture:
- Verse-by-verse commentary from Tyndale and JFB, scholars Christians have trusted for over a century, not AI-generated answers
- Easton's Bible Dictionary built in. Tap any name, place, or term to see what it means
- Three deep study sessions a week, every Mon, Wed, and Fri. Each one with SOAP (Scripture, Observation, Application, Prayer) plus a deeper Analysis view with context, key insights, original-language meaning, and related verses
- 74 study guides spanning hermeneutics (how to read the Bible), christology (who Jesus is), soteriology (what salvation means), pneumatology (the Holy Spirit), ecclesiology (the church), eschatology (the end times), and biblical theology (how the whole Bible fits together)
- 8 guided reading paths for new readers, small group leaders, anyone working through doubt, sermon prep, and more
- The Berean Standard Bible bundled, plus more translations available to download in-app
- Word study tools that make Greek and Hebrew meanings approachable, no seminary degree required
- Sermon Notes with verse lookup and auto-save, so you can capture the message in real time
- Verse highlights and notes that sync across your devices
- A reading tracker that helps you build a habit that lasts
