Network Doctor: WiFi Check

Speed looks normal, but calls still lag? Network Doctor checks Wi-Fi or cellular connections to help you understand what the measurements show.

Start for free:
• Measure download and upload speed
• Check idle and loaded latency, DNS, and selected services
• See basic measurements and a summary of detected issues
• Keep your checks on your device and revisit basic results
• Add public HTTPS targets you want to check

Complete Diagnosis is an optional, one-time in-app purchase:
• Detailed findings and possible explanations
• Practical steps to try and ways to verify changes
• Full service results and run evidence
• Notes, complete report sharing, and CSV export

One purchase unlocks complete diagnosis for saved and future checks. No subscription or per-report charge. Previous customers keep their existing access and can restore it using the same Apple Account.

Results distinguish measurements from possible causes. Available measurements depend on your connection and the services tested; diagnosis cannot guarantee a fix.

No account, ads, or third-party analytics. Reports stay on your device unless you choose to share them. Delete saved reports at any time.
