Hello! Welcome to the Community!
Unfortunately, Infinite Flight is not on the supported list of apps for Navigraph Simlink - it only works with MSFS, Prepar3D and XPlane. Simlink also cannot be downloaded for iOS or Android, it’s only available on Mac/Windows. The only link we have with a Navigraph product is with Simbrief - their flight planner, which we have direct integration with. See below for more information:
If you are wanting something similar to what Simlink provides, Infinite Flight has links with both ForeFlight and Garmin Pilot.
