Connection Check shows you, in plain language, the network path iOS makes available to apps on your device — whether you are online, which interfaces are in use, and whether the network is expensive or in Low Data Mode. It is a focused, privacy-first utility: no account, no ads, no tracking, and nothing leaves your device. AT A GLANCE See an instant Online, Offline, or "Requires connection" status, with a clear explanation of what it means for your apps. INTERFACES Check whether the current path may use Wi-Fi, Cellular, Wired Ethernet, Loopback, or another interface type. Tap any row to learn what it means. NETWORK CONDITIONS Find out if iOS considers your connection "expensive" (such as cellular or Personal Hotspot) or "constrained" by Low Data Mode — the same signals well-behaved apps use to save your data. PLAIN-LANGUAGE EXPLANATIONS Every status, interface, and condition comes with a friendly explanation, plus the underlying technical detail for the curious and for developers. TECHNICAL DETAILS & DIAGNOSTICS Expand the technical section to see raw values (path status, interface availability, DNS / IPv4 / IPv6 support) and copy a clean, plain-text diagnostic summary to share with support. TEST REQUEST Run a single small request and watch how per-request policy toggles — allow cellular, expensive, or constrained access — change the outcome. These settings apply only to this app's own request, never to your whole phone. WHAT THIS APP CANNOT DO Connection Check cannot read your total mobile data usage, your carrier usage, or other apps' data usage. It only shows the network path information iOS makes available to this app. PRIVACY No sign-in. No analytics. No tracking. Nothing is collected or sent anywhere.
