Judo for iOS and iPadOS is a companion to the Judo Mac app available in the Mac App Store.
Use the mobile app to open your Judo designs created with the Mac app on a real device. Scroll, tap, swipe and navigate to preview the user experience before integrating your design into your own app.
Send Judo files from your Mac to your phone with AirDrop or save your files in iCloud to sync them to your phone automatically.
Just gave this a shot. It's a cool concept but pretty clunky. Navigating the canvas in particular - missing patterns from Photoshop/Figma like holding space bar to get a "hand" tool to move the canvas around. Selecting items from the sidebar doesn't zoom to them. Feels like a 0.5 instead of 2.0 app.
Honestly I'd recommend Xcode previews over this for designers.
Great platform for quickly building native experiences
Judo empowers me as a designer/developer to build native, in-app experiences in a fraction of the time. The Judo app is intuitive and easy to use, and allows me quickly advance from prototypes to production ready experiences.
