SpeedTest is a comprehensive network diagnostic tool for iOS that addresses common needs like verifying internet speeds and assessing WiFi health. It offers real-time testing for download and upload speeds across WiFi, 4G, and 5G networks, which is crucial for activities such as streaming, video conferencing, or online gaming. The app includes a WiFi analyzer feature that visually maps signal strength, helping users identify weak spots in homes or offices. For example, someone dealing with intermittent connectivity can use the heatmap to reposition their router effectively. Reviews indicate that users appreciate the one-tap speed tests for their consistency and speed, often comparing results to ISP claims. However, the free version contains advertisements that some find distracting, and advanced features like detailed packet loss reports may require a subscription. In practical scenarios, travelers can rely on it to evaluate hotel WiFi, while remote workers might track historical data to spot performance trends. Despite occasional interface sluggishness on older iPhones, the app remains a reliable choice for everyday network diagnostics, balancing ease of use with functional depth.

I was constantly frustrated with my slow internet until I used SpeedTest. The signal map revealed a dead zone in my living room, and after moving the router, my streaming issues vanished completely. It's become my go-to for any network problem.
