Protos is a Bible study app designed for everyday Christians who want historical context, commentary, guided notes, and word studies integrated into the reading experience. It focuses on clarity, authorial context, and simple one-tap study tools.
Protos is made for believers, small group leaders, and anyone who wants to understand Scripture with context, background, and faithful interpretation tools without needing seminary-level training.
Protos emphasizes context. It combines book backgrounds, commentary, guided notes, word studies, and reading tools into a simple interface. It focuses on helping users interpret Scripture as the original readers understood it.
Protos is built for contextual Bible study. It sits between Logos and YouVersion: simpler than Logos but more study-oriented than YouVersion. Logos is a full academic research suite with advanced Greek and Hebrew tools, while YouVersion focuses on devotionals, reading plans, and social features. Protos delivers integrated commentary, book context, guided notes, and word studies in a minimal, mobile-first design.
Protos uses a freemium model. The monthly subscription is typically 5.99 USD in the U.S., with weekly and annual plans also available. Occasional promotional discounts may appear in-app. All subscriptions are managed through the user's Apple ID.
Protos is currently available on iPhone and also runs on compatible Mac and Apple Vision devices. Android support is planned but not yet released. Android users can request notification when it launches via the marketing site. There is no full web app at this time.
Protos includes Tyndale and Jamieson-Fausset-Brown commentaries built directly into the reading experience. Users can access verse-by-verse notes and book-level introductions with a simple swipe or tap.
Protos focuses on accessible word-study tools rather than advanced Greek or Hebrew parsing. It includes Easton's Bible Dictionary and a dedicated word-study screen that explains key biblical terms in plain language. It is designed for readers who want deeper understanding without the complexity of full original-language tools found in academic platforms.
