## What is WiFi Health Check?

WiFi Health Check helps you check your Wi-Fi connection, identify devices on your local network, and understand connectivity problems.

Built for home networks, homelabs, and everyday IT troubleshooting, it brings connection diagnostics, device fingerprints, stability tests, and room comparisons to iPhone and iPad.

WI-FI HEALTH
See how your current connection is performing with clear results and practical guidance.

- Connection experience score and recent check results
- Local gateway, DNS, and internet connectivity checks
- Current Wi-Fi and network information when available
- Explanations of detected issues and suggested next steps

Results reflect the tested connection, rather than Wi-Fi signal strength or channel conditions.

LOCAL NETWORK DISCOVERY
Scan your selected local subnet to discover responding devices and common services.

- Identify computers, phones, tablets, routers, servers, NAS devices, printers, and cameras when sufficient evidence is available
- View device identity, IP address, and available manufacturer information
- Review device counts and categories
- Save devices for later reference
- Compare results with previous scans

DEVICE FINGERPRINTS
Go beyond a single open port. WiFi Health Check combines TCP services, HTTP and HTTPS responses, Bonjour / mDNS, SSH banners, and platform signatures to identify devices.

Supported fingerprints include:
- FortiGate / FortiOS
- Synology DSM
- Proxmox VE and VMware
- MikroTik RouterOS and OpenWrt
- UniFi and TP-Link Omada
- ASUSWRT
- Hikvision and EZVIZ devices
- Docker and Portainer
- Common databases, media platforms, printers, and file services

Identification depends on the evidence a device exposes. Devices without sufficient evidence remain unclassified.

CONNECTION STABILITY
Test a reachable host and port to observe connection performance over time.

- Live TCP response measurements
- Successful connections, failures, and timeouts
- Response-time trends
- Saved targets and test history

WALK TEST & ROOM COMPARISONS
Check connection performance in different areas of your home or workplace.

- Test the same target in each room
- Review response times, failed connections, and slow spikes
- Use PRO to save locations and compare rooms
- Compare measurements before and after network adjustments

Area scores are estimates of connection experience. They do not measure radio signal strength, and public targets can also reflect internet-provider conditions.

WI-FI ROAMING
Observe what happens to your connection as you move between access points.

- Track available Wi-Fi names and BSSID changes
- Review the observed roaming path
- Check TCP continuity and response times during movement

Roaming tests observe connection behavior at the application level. They do not measure exact wireless handoff times. Keep the app in the foreground during testing.

SERVICE INSIGHTS
Understand common services detected on your network, including SSH, HTTPS, SMB, RDP, WinRM, RTSP, databases, media servers, and management interfaces.

Potentially sensitive management services are highlighted for review. A detected service alone does not establish a vulnerability.

HISTORY & TROUBLESHOOTING
Keep useful results available for your next investigation.

- Review diagnostic, stability, roaming, and LAN scan history
- Notice new devices and changes in detected services
- Access troubleshooting guides
- View recent Wi-Fi health results through the Home Screen widget

PRIVACY
Local device discovery and fingerprint analysis run on your device. No account is required for basic network scanning.

Whether you are troubleshooting a connection or checking what is connected to your LAN, WiFi Health Check makes your network easier to understand.

## Frequently asked questions about WiFi Health Check

### What kind of network issues can WiFi HealthCheck diagnose?

WiFi HealthCheck can diagnose common DNS, TCP, HTTPS, IPv4/IPv6, captive portal, and Wi-Fi roaming issues. It inspects your current Wi-Fi and network path, tests connectivity, and checks for captive portals.

### Does WiFi HealthCheck require an account or cloud storage?

No, WiFi HealthCheck does not require an account and does not rely on cloud storage. Diagnostic results and history stay on your device by default and are only shared when you choose to export a report.

### How does the LAN TCP stability testing work in WiFi HealthCheck?

You can configure the IP address and TCP port of a local service (like a router or NAS) and run repeated connection tests. Results include connection success/failure rates, latency, and various error events.

### What information does WiFi HealthCheck provide about my current network?

It displays your current Wi-Fi name (SSID), BSSID, local IP address, estimated gateway, Wi-Fi security type, and access point vendor information, depending on iOS permissions.

### Can WiFi HealthCheck help with Wi-Fi roaming issues?

Yes, the Wi-Fi roaming test allows you to record BSSID samples, TCP continuity, and Wi-Fi node transitions as you move between locations. It provides evidence of your roaming path and latency changes.

### What is the age rating for WiFi HealthCheck?

WiFi HealthCheck has an age rating of 4+, making it suitable for a wide range of users.

### On which devices can I use WiFi HealthCheck?

WiFi HealthCheck is currently supported on iPhone devices.

### How often is WiFi HealthCheck updated?

The latest version, 1.4, was released on September 4, 2026, indicating recent development and updates.
