With ColdSpotting, you can:
Visualize the strength of your network across time and space.
Find deadspots where your reception isn't well covered and maximize reception.
Diagnose poor or intermittant network performance.
Perform site surveys to ensure high-reliability.
Test connections using real-world devices.
Compare coverage across manufactures and product lines.

How it works:
We use ARKit, the Augmented Reality framework, provided by Apple, and optimized for their specific iOS hardware. When you tap the screen we take a snapshot of the Wireless Signal Strength at a specific location and draw a virtual box into the scene that is color coded to represent the relative strength of the Wifi in that exact spot(Green is Better, Red is Worse). By moving within a space, you can take samples at different spots to create a map of your network in 3-Dimensional space.

App Instructions:
Simply Tap your screen to test Strength in a specific location. A Box will appear at that location indicating the strength of your Wifi signal by it's color(Green is Better, Red is worse Black is no reply). By moving around and repeatedly placing multiple points in an area, you can diagnose Cold Spots in your coverage.

Data Charges may apply.

Crashes immediately

Does exactly nothing on an X-RAY with latest iOS. Piece of junk, I want a refund.

ColdSpotting crashes immediately on my iPhone X.

I downloaded this app for my iPhone X today. The first time it launched, I was asked for permission to use the camera, which I granted. The app crashes a second after starting to show the live camera display.

After several attempts, I deleted and redownloaded the app. Still it crashes. I powered off and then restarted. Still it crashes. I took the update for iOS 11.2.6. Still it crashes. At this point I have to conclude that this app is a complete waste of my time and money.

Developer Response ,

Version 2.0 addresses this issue with the iPhoneX. I'm sorry you had such a bad user experience. E-mail if this isn't working for you, and I will make it right.

A very practical and elegant implementation of VR: Launch the app, tap “Start Augmented Reality,” and with Auto Drop on, just walk around the area where you want to test Wi-Fi signal strength. Where you point the camera is irrelevant; it’s where you HOLD the camera that determines where the measurements are taken. Walk faster for fewer measurements per unit of distance; walk slowly where you want more.

Turn off Auto Drop and you can control when and where a measurement is taken by tapping the screen. For example, I wanted to measure signal strength at various devices such as my irrigation timer and garage-door opener, so I moved the camera around these devices and tapped every few inches.

When you back away, you will see a square for each measurement, located in three-dimensional space, color-coded to display signal strength.

There’s not much in the way of instructions, because you don’t really need much; it’s pretty intuitive, and very impressive. It does what it says it does, it spots Wi-Fi cold spots.
