HTTPS Capture is a professional iOS packet-sniffer built for developers and network enthusiasts. No computer, no jailbreak — a single iPhone captures and decrypts all HTTP/HTTPS traffic on the device, down to every request header, response body, timing detail, and WebSocket frame. Whether it's API debugging, protocol reverse engineering, performance analysis, or everyday Mock and rewriting, HTTPS Capture packs a complete debugging toolkit once reserved for the desktop right into your pocket. All traffic is parsed and stored locally on-device. Nothing is ever uploaded to any server — your network data belongs to you alone. One-Tap Capture, Total Visibility • VPN tunnel + local MITM proxy — flip the switch and capture device-wide traffic instantly. No proxy configuration needed. • Real-time dashboard: request count, domain count, upload/download traffic at a glance. • Capture sessions …
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 12 screenshots above are HTTPS Capture Traffic Decrypt's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: HTTPS Capture Traffic Decrypt runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #FCFCFC) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #14B4A4, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
