Riv File Viewer
Test and debug Rive animations on real iPhones and iPads. No Xcode required.
Open and debug .riv files on your device
The Riv File Viewer is a free iOS and iPadOS app for testing Rive animations where they will actually run. Load a .riv from a link or from your device, then drive its state machines, edit data binding live, and inspect the fonts, images, and audio inside the file. Everything stays on your device. There is no account, and nothing is uploaded.
