RetroNotes
Local Notes and Paper Disk
RetroNotes Markdown is a local-file-based app for text, voice, visual, drawing, file transfer, and paper archive workflows. Record ideas naturally while keeping the original content as readable Markdown and TXT files.
Voice Note + Recall
Hold the Voice Note button, speak, then release. RetroNotes adds the transcription to today’s Voice Note. Original audio is not kept. Use Recall to ask questions about Voice Notes and return to the original supporting records when sufficient information is available.
Text Note
Write in a focused three-column workspace. Search titles and content to find Text Notes again quickly.
Vision Note
Import up to nine photos or screenshots. RetroNotes extracts visible text while preserving the relative position and size of each recognised text region.
Draw Note
Long-press the new-note button to open Draw Note. Draw freely on A, B, envelope, and US paper sizes without automatic shape correction. Export drawings as SVG, PDF, PNG, or editable PPTX. Visually closed drawings can be filled with colour in PowerPoint while retaining their hand-drawn outlines.
RetroDisk
Transfer files from Mac to iPhone or iPad through the Mac screen and the receiving device’s camera. RetroDisk does not require Bluetooth, AirDrop, a local network, a cable, an account, or an account-based cloud service.
Paper Disk
Turn a small important file into an encrypted printable A4 PDF archive. Each Paper Disk page stores about 10KB. To restore the file, scan every printed page with the device camera. The file restores automatically when all pages are complete.
Paper Disk is designed for reliable personal paper recovery of small essential files, such as Markdown files, TXT files, recovery notes, and key documents.
RetroNotes is available on the App Store as RetroNotes Markdown. It is a paid app with no ads, no account, no subscription, and no in-app purchases.

Recall uses a locally rebuildable index. Markdown and TXT files remain the primary data.
Privacy by Design
RetroNotes does not require an account and does not include ads, analytics, tracking services, subscriptions, or in-app purchases.
RetroNotes does not upload notes to a developer-operated server. Apple system keyboard, speech recognition, text recognition, camera, or iCloud Photos may require permission or network access.
