What it does
- Captures HTTP and HTTPS traffic from any app on your iPhone — the requests, responses, headers, bodies, and timing.
- Needs no Mac, no desktop proxy, and no jailbreak. Capture, decryption, and inspection all happen on the phone.
- Decrypts HTTPS with a certificate generated on your device. The key never leaves your iPhone.
- Identifies who each request talks to: the company, the SDK, the cloud provider, and the datacenter behind every connection.
- Plots every connection on a live 3D globe, so you can watch where in the world your data goes.
- Exports any request as a cURL command or a HAR file.
- Stores everything locally. No accounts, no analytics, no tracking — see the privacy policy.
How it works
Tracer opens a local VPN tunnel on your iPhone, so every connection the device makes passes through the app. HTTPS is decrypted with a root certificate that is generated on your device during setup and trusted by you. Nothing is routed through an external server, and nothing you capture leaves the phone.
Setup takes about a minute: setup guide.
FAQ
Do I need a Mac or a computer?
No. Tracer runs entirely on your iPhone. Unlike Charles Proxy or mitmproxy setups, there is no desktop app, no Wi-Fi proxy configuration, and no computer involved.
Does it require a jailbreak?
No. Tracer is a normal App Store app built on standard iOS APIs: a local VPN tunnel to see traffic, and a user-installed certificate to decrypt HTTPS.
How does it decrypt HTTPS?
Tracer generates a root certificate on your iPhone and walks you through installing and trusting it. Traffic is decrypted inside the local tunnel, shown to you, and re-encrypted on its way out. The certificate's private key never leaves your device, so nobody else — including us — can use it to read your traffic.
Is my captured traffic uploaded anywhere?
No. Captures are stored in a local database on your device and nowhere else. No accounts, no analytics, no tracking. Erase everything at any time from the app's settings.
Does it work with every app?
Most apps work normally during a capture and everything they send is decrypted and visible. A small number of apps use certificate pinning: they accept only their own server's certificate, so while a capture is running they may show errors or refuse to load — true with any inspection proxy, Tracer, Charles, and mitmproxy alike. Pinning doesn't hide traffic: requests a pinned app actually sends are still captured and decrypted. It just means the app may stop working until you end the capture.
What does it cost?
Free to download. Some features require a paid subscription, billed through your Apple account.
