This tool lets you scan ports on a remote host via it's IP or domain name so you can know which ports are open on the host.

It supports 3G, protocol recognition, and many other features.

If you don't understand how to use it, just send me an email, I'll explain it more precisely.

It tells you whats open but but I feel gives many false positive. Also no services scan. This is so not like nmap or amap. Just one more junk Port scanner app for Android

Not really working, when I scan the well known ports it list about 9-10 opened, but to the 1-10000 port range it says 0 port opened.

Slow on firewalled hosts. You should use Java NIO (take a look at Network Discovery, which is open source)
