Plain Markdown Read your .md files in place. Pick a folder on your iPhone or in iCloud Drive. The app lists every .md file inside — nothing more, nothing less. Tap a file to read it; the markdown is rendered with quiet, weight-driven typography that gets out of the way. The app uses Apple's standard folder picker, so it works with iCloud Drive, On My iPhone, and any third-party Files app provider (Dropbox, Google Drive, Working Copy, etc.). Pick once, and the app remembers — drill into subfolders, come back, switch folders. No accounts. No sync engine. No editor. Just a reader. Ā· Folder picker with iCloud Drive and Files-app provider support Ā· Drill into subfolders — back-button navigation Ā· Inline images (jpg, png, gif, webp, svg, heic, heif, bmp, avif) Ā· GitHub-flavored markdown: tables, blockquotes, code blocks, task lists, strikethrough Ā· Adjustable text size (5 steps) Ā· Light & dark mode Ā· Mono body font option for code-style reading Ā· Local only — your files never leave your device Privacy This app does not collect data, display ads, or communicate with any server. The folder picker is Apple's. Files are read on-device only. There are no analytics, no third-party SDKs, no telemetry. Less, but better.

No folder to pick first. • Notes become plans — write one line, tap "Let Prubi sort this", and the date and time land on your calendar. • Check it, color it, remind me — checklists, 6 colors and reminders. • Your week at a glance — weekly planner, a 24-hour day view and D-day. • "Where did I write that?" — ask, and the AI finds it in your own notes and shows exactly which notes it read. BUILT TO TRUST, BUILT TO LAST • A vault only you can open — passwords, account numbers and ID photos are encrypted on your device before upload; the server keeps only ciphertext. • Write on your phone, continue on PC — same account, same notes on phone, PC and tablet. • 16 languages Ā· no ads Ā· no data selling Ā· your notes are not used to train AI models. • Export notes to Word, PDF or Excel, and delete your account any time.
