Help
Something has stopped, and you want it working again. Find the sentence below that sounds like your problem. Every page names the cause first, then the steps, then what to do when the steps did not help — because a fix list that assumes the fix worked is the reason you are reading a second page.
Almost everything that goes wrong here is one of four things, and none of them is GPSLarp: the iPhone and the Mac have not been introduced to each other, iOS is holding a switch closed that it will not open without being asked, macOS wants a password before anything touches a device, or the network the two devices share is not the one you think it is.
01The iPhone side
- GPSLarp can't find my iPhone The connection is up and the device list is empty. The three causes, in the order worth checking, and why the app cannot tell you which one it is.
- My iPhone won't trust this computer The prompt never appears, appears and does nothing, or you tapped Don't Trust. How to get it back, including the reset that clears every pairing on the phone.
- Developer Mode isn't showing on my iPhone Why the switch is missing from Settings until a computer has asked for it, and what to do about the restart and the passcode prompt that follow.
02The Mac side
- GPSLarp is asking for my Mac's administrator password What the prompt is, what it starts, why it is macOS's own dialog rather than ours, and what happens if you dismiss it.
- The installer won't open, or I can't find the app Where the installer puts GPSLarp, what Gatekeeper should and should not say about it, and how to check the download you have is the one we published.
- I can't sign in to GPSLarp The browser opens and nothing comes back, the app keeps asking, or you are offline. What each of those means and what to try.
03Setting a location
- I picked a place and my iPhone's location didn't change Where the chain breaks between the map on your Mac and the map on your phone, which apps read the changed value and which do not, and what this page will not claim.
- How do I put my real location back? Three ways, all of them immediate, none of them requiring a restart. Including the one that still works when your session has lapsed.
04Before you start
05What is not on this page
Two questions get asked constantly in this category and are missing from the list above on purpose.
Whether an app can tell
GPSLarp changes what the phone reports at the system level, so an app reads it the way it reads a real GPS fix. That is a description of the mechanism and not a promise about anyone's detection: some apps run their own checks and enforce their own terms against location spoofing regardless of how it was done. No immunity from another company's policy is offered here, because none can be. Decide what that means for you before relying on this for anything that matters.
Whether the location holds
The best-known complaint in this whole category is that a spoofed location reverts by itself after a minute or two. There is no page here about that, and the reason is that nobody has measured whether GPSLarp does it. Writing a confident page about a defect this product might share, or claiming it is immune, would be inventing an answer — and the person who would pay for the invention is the reader. When it has been measured, it gets a page.
06Still stuck
The home page describes what GPSLarp does, what it needs and what it costs. The terms are the contract, and the privacy policy lists every service the app contacts from your machine. If you have an account, you can export or delete everything held about you from it.
