LocoLarp

iPhone from Windows

Apple does not give third-party iPhone apps a mock-location picker like Android. LocoLarp Desktop is a Windows program that plugs into the same developer location-simulation channel Xcode uses. It is not an IPA and it is not listed on the App Store.

What you need

  1. Windows 10 or 11.
  2. A USB data cable (charge-only cables will not pair).
  3. Apple’s USB stack: install Apple Devices from the Microsoft Store, or iTunes for Windows.
  4. A LocoLarp license key from Buy. The same key unlocks the Android APK and Desktop. Start stays locked without a key.

On the iPhone

  1. Unlock the phone and connect the cable.
  2. Tap Trust This Computer and enter the passcode.
  3. iOS 16 or later: open Settings → Privacy & Security → Developer Mode, turn it on, and let the phone restart.

Prefer a click-through? Use the setup wizard. It downloads Desktop, walks through Trust / Developer Mode, and can check a license key.

In LocoLarp Desktop

  1. Download the Windows installer from the download page, or from this repository run cd desktop, then npm install and npm run pack.
  2. Paste the license key under Session → Settings and save it. The same key unlocks the Android APK.
  3. Search or tap the map, then Start. That one click pairs the phone, opens the iOS 17+ tunnel if needed, and holds the test location. Approve Trust and a Windows administrator prompt if they appear.
  4. Walk and Drive follow OpenStreetMap roads. If a simulation is already running, clicking a new point asks before moving. Restore (or a reboot) returns real GPS.

If the phone never appears

  • Try another cable and a USB port directly on the PC, not a hub.
  • Open Apple Devices / iTunes once so the USB service starts.
  • Unlock the iPhone and keep the screen on while pairing.
  • On iOS 17+, the tunnel must be running before Start will change other apps’ GPS.

Android setup is unchanged. See Android setup for the APK.
