WhiteSail: Live Internet Check

WiFi & Cellular: Better Spots

Only for iPhone

$5.99

iPhone

See how Wi-Fi or cellular feels right now. Compare five-second checks at home or outdoors to find better spots for gaming, video, and calls. Not sure whether your bed, desk, or sofa works better for gaming at home? Does cellular feel unstable outdoors or while traveling? Need a better spot for a video call at a café, office, or hotel? WhiteSail helps you compare the network experience at places you test yourself, so you can choose better spots for gaming, video, and calls. On the Live tab, WhiteSail continuously updates experience metrics while the app is active and in the foreground. It focuses on responsiveness, stability, and interruptions rather than measuring Mbps bandwidth. Run a check of about five seconds at each place you use. Saved results are filtered to your current Wi-Fi or cellular connection, so you can compare the places you have tested. WhiteSail does not scan nearby signals or recommend a spot before you test it. PRIVACY No account, no ads, and no tracking SDKs. Location access is used only so iOS can return the current Wi-Fi name; WhiteSail does not request or save your coordinates. Connectivity checks contact external network providers, which may process request metadata such as IP address under their own policies. IMPORTANT LIMITS WhiteSail measures responsiveness, stability, and interruptions rather than Mbps throughput, and it cannot strengthen network coverage. It only helps you choose a better spot from the places you have tested.
