## What is WiFi HealthCheck?

WiFi Health Check is an on-device WiFi and LAN diagnostic tool for iPhone. It helps you quickly understand whether your current network is reachable and stable, and which WiFi access point your phone is connected to.

No account is required, and it does not rely on the cloud. Diagnostic records are saved locally by default. You can perform a quick network check at home, in the office, in a server room, at a store, or at a customer site, and generate a shareable diagnostic report.

Key Features:

One‑Tap Network Diagnosis
Checks public website connectivity, DNS resolution, gateway information, device IP address, current WiFi name (SSID), BSSID, WiFi security type, and more.

LAN TCP Continuous Test
Performs continuous TCP tests against routers, NAS devices, printers, Proxmox hosts, servers, AP management addresses, or other LAN devices. Monitor latency, timeouts, and stability.

WiFi Roaming Test
Records the currently connected SSID/BSSID as you move around, helping you determine whether your phone has switched from one WiFi access point to another.

LAN Scan Report
Runs a lightweight local scan within the current subnet and lists discoverable LAN devices along with open ports, assisting in network environment troubleshooting.

Local History & Share Reports
Results of diagnostics, continuous tests, roaming tests, and LAN scans are saved locally by default. You can view them anytime and share them as text reports.

Language Interface
Supports switching between Chinese and English. Your language preference is stored locally.

Privacy Notice:
WiFi Health Check requires no account, does not upload diagnostic history, and does not read your WiFi password. Location permission is used solely to allow the app to read the current WiFi name and BSSID on iOS. Reports are distributed only through the method you choose when you actively share them.

## Version history (last 3 releases)

### 1.2 — 2026-08-18

1. Added WiFi roaming quality testing.
2. Quick roaming test now works without entering an IP address or port, using a public HTTPS target to observe  application-layer continuity while walking.
3. Added Advanced roaming test with a custom LAN TCP target for more focused AP transition checks.
4.  Improved BSSID Only mode so it only tracks WiFi node changes without mixing in TCP timeout or packet-loss wording.
5. Improved LAN Scan discovery across more common service ports without requiring 80/443 to be open.
6. Improved subnet calculation using the real netmask with safer limits for large networks.
7. Added better captive portal detection to avoid treating sign-in portals as normal internet success.
8. Added privacy manifest support while keeping diagnostics local, account-free, and user-controlled.

### 1.1 — 2026-08-01

1. Improved One-Tap Diagnostic results. DNS Lookup now shows the DNS server, IP address, and domain used for the test.
2. Improved public website connectivity results by showing the actual website target used during the test.
3. Enhanced LAN Scan to identify more common local device service ports, including NAS, Proxmox, printers, file sharing, and web management services.
4. Refined LAN Scan behavior and descriptions. Scans are limited to the current Wi‑Fi LAN, and results stay on the device by default.

### 1.0 — 2026-07-23

No release notes.
