Stand where the problem is.
Name the room, describe the complaint, and capture 30 seconds of the device’s connection and supported network checks.
For conference & event teams
“The Wi-Fi
isn’t working.”
Bring evidence.
Give your engineer more than a complaint. Capture a short view of one device’s connection, make a change, and compare what happened.
A gift to the public. No account. No activation. No license.

Did the change help?
Same device. Same place. 30 seconds each.
| Measured evidence | Before | After |
|---|---|---|
| First response | 3.8 s | 0.8 s |
| DNS response | 620 ms | 34 ms |
| AP changes observed | 2 | 0 |
| Signal · median | −67 dBm | −59 dBm |
A clearer handoff. A better next question.
Example data. Request timing is not full page-load time. Observations alone do not establish cause.

Built around the handoff
From “it’s broken”
to “here’s what we saw.”
When a room full of guests has a problem, event staff and engineers need a common starting point. Snapshot is being built to make that conversation easier.
Try the change. Check again.
Take another snapshot from the same spot. Compare signal, observed AP changes, response timings and the evidence each platform can provide.
Give engineering something useful.
The planned export includes a readable report and AirWitness-compatible snapshot files, so the investigation can continue.
One client’s experience
Useful evidence.
Honest limits.
Snapshot focuses on what this device could observe during this capture. A missing measurement stays missing.
Try the Android, Windows & Mac interface concept →Connection changes over time
Look for observed AP changes and disconnects during the window. A short capture cannot provide a complete roaming history.
Wi-Fi quality, explained
A planned factor breakdown shows how the estimate was calculated and which inputs were unavailable. The Wi-Fi score is separate from connectivity checks.
Timings beside radio observations
Compare supported DNS and request timings with the connection evidence. One timed request is not a browser page-load test.
Free on every platform
Your device.
Your snapshot.
Windows, macOS and Android are the first targets. Public installers will appear here once each build is ready. No registration or license will be required.

A portable view of the guest’s connection.
Public APK in preparationAndroid will be distributed here as a direct APK download while we work toward Google Play. The experimental measurement lab is not a public Snapshot release.
How will I install the Android APK?
Once the public APK is available, download it directly to your Android device. Open the file and, if Android asks, allow that browser or file manager to install this app. That permission can be turned off again afterward. No root access or bootloader changes are needed.
A few useful answers
Small tool.
Clear purpose.
Is Snapshot really free?
Yes. Snapshot is a gift to the public. The planned Windows, macOS and Android versions have no account, activation or license requirement.
Does this replace AirWitness?
No. Snapshot is the focused capture, compare and handoff tool. The full AirWitness application provides a broader troubleshooting workspace. Snapshot v1 is being built to read and write compatible snapshot files in both directions; it may display only part of a richer AirWitness file.
Can one tablet diagnose an entire event?
It records one client’s experience at a particular place and time. It does not measure every guest, access-point load or venue-wide capacity. It gives engineering a concrete piece of evidence to investigate.
Why does Android ask for location permission?
Android requires location permission and enabled location services for certain Wi-Fi observations. Supported measurements vary with Android version, device hardware and permissions. Unavailable information will be labelled accordingly.
Where does the information go?
The planned capture workflow keeps evidence on your device until you choose to export or share it. Connectivity checks make requests to the configured test services, which receive the source IP and ordinary request metadata. This landing page uses no analytics scripts or tracking cookies. See the AirWitness privacy policy for website logging and service information.
What about Linux and iOS?
Linux is planned for a later phase. iOS is not part of the first release; its available Wi-Fi observations differ substantially.
