What devices support Friction?
iPad - any iPad running iOS 14 or later.
Mac - any Mac running macOS 10.15 (Catalina) or later.

What do the version numbers mean?
The version numbers use semantic versioning, therefore, it is in the format MAJOR.MINOR.PATCH

In order to maintain compatibility between the mac version and iPad version, ensure that they both use the same MAJOR version. MINOR versions generally refer to small device-specific changes and PATCH versions generally refer to bug fixes and small minor improvements.

What technologies does Friction use?
We use Peertalk to communicate between the iPad and Mac.

Interface-wise we use SwiftUI for most of the it. For the Mac app, there's a little bit of AppKit to manage windows and overlay drawings on top of the screen. For the iPad app we used UIKit for certain UI elements and interactions that were not possible in SwiftUI.

We used PencilKit to create the drawing canvas and get Apple Pencil/finger input.

It's mostly written in Swift with some Objective-C.

Now go and build your own Friction.

No tracking, no ads, none of that.
