About

OdaViewer

Features
Read full description

The companion for Oda on the Mac. OdaViewer brings your Oda archive to iPhone and iPad. Browse your folders, search across everything, and preview your documents โ€” the same structure you keep on your Mac. And now it writes back. Notes aren't read-only anymore: write them, edit them, tick things off, in the same editor you have on the Mac. Same format bar, same headings, same checklists. Tap into a note to write, swipe the keyboard down to read it as a clean page. Dictation works inside lists โ€” dictate an item, say return, dictate the next one. It's the same note on both machines. It also captures. Scan a document, pick a photo, grab a file, write a note, or share a PDF straight from another app. OdaViewer holds it until your phone and Mac meet on your local network, then sends it over โ€” where it's waiting on your Mac for you to file. What you capture stays visible under Captured until it's filed. A capture you can't lose. Everything syncs over your local Wi-Fi with Bonjour. No cloud, no account โ€” your documents stay between your own devices. โ€” Write and edit notes, on the device โ€” Browse, search, and preview your whole archive โ€” Capture: Scan, Note, Photos, Files, and share from other apps โ€” Library, Tags, Stickies, and Binders, matching your Mac โ€” Local sync over Bonjour โ€” no cloud involved Requires Oda for Mac. Sync needs both devices on the same local network.
