Only download RangeFlux from this page. The app checks your license online, and keeps working offline for 24 hours after the last check — how license checks work

Setup

Up and solving in three steps.

  1. Get a Local Solver license

    Buy a Local Solver license on Pricing; the key arrives by email right after checkout. Already purchased? Sign in to the app and use Restore purchase in Settings → Account.

  2. Open the app

    RangeFlux is not code-signed yet, so your OS warns on first launch.

    macOS 15+
    Open once, then System Settings → Privacy & Security → Open Anyway
    macOS 11–14
    Right-click the app → Open
    Windows
    SmartScreen: More info → Run anyway

    Still stuck? See Installing.
