Device ID Check Tool vs HTTPGlass

A lightweight tool for easily checking and sharing your Identifier for Advertisers (IDFA). Perfect for mobile marketers and app developers, IDFA Checker lets you copy your device's identifier with a single tap. Monitor your tracking status simultaneously to help debug and analyze marketing campaigns. Designed with privacy in mind, all data is processed locally on your device without external transmission. This essential tool supports iOS 14+ advertising identifier management requirements for today's privacy-conscious mobile ecosystem.

See every request your apps make — from your iPhone, with no Mac and no cable. HTTPGlass is a full HTTP(S) debugging proxy that runs entirely on-device. It installs a local VPN profile and its own root certificate, then captures and decrypts traffic from the apps on your phone the way a desktop proxy would. Nothing is relayed through a server and there is no account to create. CAPTURE • Every request and response, with status, method, host, timing and size • HTTPS decryption through an on-device root CA you install and trust yourself • HTTP/1.1 and HTTP/2, gzip, deflate, Brotli and chunked bodies decoded for you • Full-text search across URLs, headers and bodies • Sessions: browse, scope, rename, share and delete each capture run READ • Body viewers: pretty JSON, tree, field list, raw and hex • GraphQL inspector — operations and variables, not a wall of escaped text • WebSocket frame viewer • Image and form-body previews • Export to HAR, or generate a cURL / Swift / Python / JavaScript / Kotlin snippet CHANGE • Breakpoints — pause a request or a response, edit any header or the body, then send it • Map Local — answer a request with a mocked response, no backend needed • Map Remote — send a request to a different host or path • Rewrite — rules that add, replace or remove headers, query items and body text • Scripting — onRequest and onResponse hooks in JavaScript, run on-device against live traffic • Compose and replay any request • Network Condition — throttle bandwidth and add latency to test on a bad connection CONTROL • Block, Allow and SSL Proxying lists so you only capture what you care about • No-Cache rules • Face ID / Touch ID app lock over captured traffic • iPad split view: the traffic list and the detail side by side PRIVACY Captured traffic never leaves your device. No cloud relay, no account, no advertising identifier. Optional, opt-in usage analytics and crash reports can be turned on or off at any time in Settings, and they never include captured traffic — no hostnames, URLs, headers, bodies or certificates. FREE AND PRO Free includes capture, decryption, every body viewer, search, sessions, export, code generation, one Block pattern, one Allow pattern, one SSL Proxying pattern and one request + one response breakpoint pattern. HTTPGlass Pro unlocks unlimited Block / Allow / SSL Proxying patterns, Decrypt all, No-Cache, Map Local and unlimited breakpoints. $8.99/month or $39.99/year with a 3-day free trial.

Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://httpglass.com/privacy/ Requires iOS 18. HTTPGlass debugs traffic from apps on this device only — it is a developer tool, not a network monitor for other people's devices.
