About this app
Scan TCP ports on any host or IP — and see what’s actually open. Advanced Port Scanner is a fast, clear TCP port scanner for iPhone and iPad. Enter a hostname, domain, or IP address, choose a port range or a custom port list, then watch live results: open or closed, service name, response time. Use it to check a home server, verify a firewall rule, or confirm that SSH, HTTP, HTTPS, FTP, DNS, or Remote Desktop (RDP) is reachable. KEY FEATURES • Fast TCP port scanning Scan any host or IP address. Domain names are resolved automatically. Check TCP ports from 1 to 65535 with concurrent workers so large ranges finish quickly. • Range or custom port list Scan a continuous range such as 1–1024 or 8000–8100, or paste a mixed list like 22,80,443,3306,3389,8000-8010. • Live progress See scanned vs total ports, how many are open, and elapsed time while the scan runs. Stop at any time. • Ope…
App details
What you can learn from Advanced Port Scanner
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 6 screenshots above are Advanced Port Scanner's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Advanced Port Scanner runs a light set with one background colour (#F4F4FC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #445C7C, 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.
