Wi-Fi 3D

Find a better spot for Wi-Fi or mobile data. Follow a colored 3D trail and compare connection quality as you walk.

Find the places where your connection works better. Walk around with your iPhone and compare Wi-Fi or mobile connectivity along a colored 3D trail in the camera view. The color changes continuously as measurements update. Pause whenever you need to; the recorded trail stays until you clear it or change networks.

For Wi-Fi, the app checks replies from the local router: latency, unanswered requests and jitter. For mobile data, it combines the iOS connection-quality estimate, when available, with small internet probes to Cloudflare, approximately once per second. You can choose Auto, Wi-Fi or Mobile network.

Internet latency is not radio signal strength. The app does not measure download speed, locate a router or cell tower, or measure your distance to one. Gray sections mean there is no recent measurement. A router may block ping, so unanswered requests alone do not prove weak reception.

Free, with no ads, in-app purchases or account. Camera images and the room map are processed on your iPhone; the app does not record photos or video or send room data to the developer. In mobile mode, Cloudflare receives your source IP address through the probes.

Camera and local-network access are required. Location permission is optional and only used to show the Wi-Fi name. Requires an ARKit-compatible iPhone with iOS 17 or later.
