Frequently asked questions
Didn't find your answer? Reach me through any channel above.
Can't read Wi-Fi data or scan?
Make sure Location permission is granted in system settings (a technical prerequisite for reading Wi-Fi data on Apple platforms) and Wi-Fi is on in Control Center. The app never reads your GPS coordinates.
LAN device tests fail?
Allow Local Network permission, and make sure the test target (gateway, AC, NAS) is on the same LAN with no firewall blocking the relevant ports.
The heatmap doesn't match what I feel on site?
Heatmap quality depends on sample-point density and evenness — re-sample similar locations and regenerate. Measurements are for reference only and not for legally certified use.
Will my projects survive a device switch?
NetGraph uses no cloud sync; projects live only on the device. Export a .Sigs package before switching and import it on the new device.
Where is Restore Purchases?
With the Apple ID you purchased with, use Restore Purchases in the app's Pro/purchase section.
