Simple Interceptor

Postman + Charles in your pocket. Capture HTTPS traffic, build & replay requests, import cURL — all on your iPhone. No Mac, no laptop, no cable needed.

Simple Interceptor = Postman + Charles, on your iPhone.

Capture, inspect, and replay HTTP/HTTPS traffic — anywhere, anytime, without a desktop. Whether you're debugging an API on the go, reverse-engineering a third-party SDK, or verifying your app's network behavior in the field, Simple Interceptor gives you the power of professional desktop tools in a single mobile app.

— CAPTURE & DECRYPT HTTPS TRAFFIC — • Real-time interception of all HTTP and HTTPS connections • Built-in MITM proxy with automatic CA certificate generation • View full request & response headers, bodies, and timing • Decode gzip, deflate, and Brotli compressed responses automatically • Filter by domain, HTTP method, status code, or full-text search • Domain whitelist/blacklist rules for focused capture sessions

— BUILD & SEND REQUESTS (like Postman) — • Craft custom HTTP requests with any method, headers, and body • Import cURL commands directly — paste from docs, Slack, or terminal • Inspect full responses with syntax-highlighted body preview • Re-send captured traffic to reproduce or modify requests instantly • Request history with iCloud sync across all your devices

— EXPORT & SHARE — • Convert any captured request to a ready-to-run cURL command • Copy headers, bodies, or full responses to clipboard • Share diagnostic logs for team collaboration

— EXTRAS — • NFC tag reading and writing (text, URL, custom MIME) • Apple Sign-In with iCloud profile sync • Unified log viewer with source and severity filtering • Step-by-step certificate installation guide

— WHO IS IT FOR? — • Mobile developers testing APIs without a laptop • QA engineers verifying network behavior on real devices • Security researchers analyzing HTTPS traffic • Backend developers debugging webhooks and callbacks • Anyone who needs Charles or Postman but only has an iPhone

No Mac required. No USB cable. No complicated setup. Just install, tap Capture, and start inspecting.

Privacy first — your traffic data stays on your device unless you choose to sync via iCloud.
