TheoPad is the specialized, local notes app for Jehovah's Witnesses—designed to provide optimal support for your personal Bible study, meetings, and preaching work. The focus is on what matters most: writing without constantly switching between apps. Here's what TheoPad offers: Automatic Bible Integration (NWT) Simply type Bible verses into your text (e.g., "Matthew 24:14" or "Psalm 23:1-4"). TheoPad automatically recognizes them, links them, and displays the New World Translation verse directly in a preview window. This helps you stay in the flow of writing while studying or preparing for the preaching work. Convention Program Import You can directly import programs for regional or circuit conventions (as RTF or ZIP files). TheoPad automatically creates a structured outline, so you can immediately record your notes for each talk in the right place. Networked Study & Structure - Note Linking: Link your notes together. Ideal for creating cross-references between different study projects or lectures. - Focus Editor: A clear editor with formatting options (bold, italics, lists) for your thoughts, lectures, or comments. Organization Your Way Organize your notes in folders or use tags to quickly find topics. Pin important notes for ministry or meetings for quick access. If you accidentally delete something, the trash keeps your data safe. Your Data Belongs to You (Privacy First) TheoPad stores everything locally on your device. - No Registration, No Tracking: We don't collect any data. - Backup Option: Use manual backup or the encrypted system backup (Google Drive / iCloud) to take your data with you when switching devices. Customizable Design Use dark mode for relaxed reading during meetings or customize the app's accent color to suit your personal taste. IMPORTANT: Setup After Installation For copyright reasons, TheoPad does not include pre-installed Bible texts. To enable automatic detection, you must import the Bible file from jw.org once. This is explained simply in the app and can be done in just a few steps. Once the import is complete, TheoPad works completely offline. Legal Notice: TheoPad is a private project by a single developer and is not officially affiliated with jw.org or the Watch Tower Bible and Tract Society.
