OpenDisplay vs Orvena

OpenDisplay turns your iPhone or iPad into a second display for your Mac. It's the open-source way to put your spare Apple device to work as a real extended monitor — drag windows onto it, keep chat, notes, or logs in view, and gain screen space anywhere you go. It's not a mirror: it's a genuine additional display your Mac treats like any other monitor. • Real extended display — arrange it in your Mac's Display settings and drag windows across • Connect over USB for the lowest latency, or over Wi-Fi with zero setup • Retina-sharp, pixel-for-pixel rendering • Touch and scroll — tap, drag, and two-finger scroll to control your Mac • Works in portrait or landscape • Private by design — a direct connection between your own devices, with no accounts, no servers, and no tracking IMPORTANT: OpenDisplay requires the companion OpenDisplay app for Mac, running on your computer on the same cable or Wi-Fi network. Get it at opendisplay.app — without it, this app has nothing to connect to. OpenDisplay is open source under the GPL-3.0 license.

Orvena is a complete assistant that runs on your iPhone. Its models run on the device itself, so conversations stay on your phone unless you choose a cloud model. There is no account, no Orvena server, and no analytics. ASK, AND IT GETS DONE Orvena works with the phone you already have: calendar, reminders, alarms and timers, maps and travel times, photos, Apple Health summaries, music, and files. Every action leaves a receipt you can read, and anything consequential asks for your approval before it runs. APPLE INTELLIGENCE, BUILT IN On iOS 27, Orvena can answer with Apple's on-device model, with nothing to download. It uses the same tools, receipts and approvals as Orvena's own model. You can also ask Orvena from Siri, Shortcuts, Spotlight and the Action button, and get the answer right where you asked. PRIVATE BY ARCHITECTURE Privacy pages usually ask for trust. Orvena's is a list: everything the app can ever send is enumerated in a short ledger in the privacy policy. On-device features work without any data leaving the phone, and anything that could ever leave asks first through a named consent step. ONE PURCHASE UNLOCKS THE REST The on-device assistant, every phone tool, web search and reading, and image understanding are free, without limits or a trial clock. A single one-time purchase adds: • Voice conversations, with a natural voice generated on the device • Connections to services you use, like Notion, Linear, GitHub, Home Assistant, and any MCP server, with sign-in built in • Apple's Private Cloud Compute on iOS 27, a larger model on Apple's servers that doesn't keep your data, within a daily limit Apple sets • Cloud models with your own API key, when you want a bigger model • Scheduled tasks, so Orvena can check on things at the right time and report back There is no subscription. REQUIREMENTS Orvena's own model runs on the phone itself, which needs recent hardware: iPhone 15 Pro or newer with 8 GB of memory, on iOS 26. The model, about 3.5 GB, downloads once. On iOS 27, iPhones with Apple Intelligence turned on can start with Apple's model instead, without the download.
