Servers Ultimate is an Android application available from the Play Store that allows your device to run 15 different types of servers on your phone. The free version allows for up to three fully functional servers running at any one time, while the paid version allows for as many as you want.

Some highlights of the available servers include running your own FTP server serving files off your SD card, a web server that you can take anywhere and update on the phone, or a DLNA server so devices on the local network can connect and watch your videos and listen to your music.

It’s a fairly impressive set of server features, and most people won’t require going to a pro version – but if you do, I’d be interested in hearing what setup you have running that requires that.

Servers Ultimate is not the most end-user friendly product. But then again, if you’re attempting to set up a roaming DLNA server or an FTP server for friends or a mobile web server, chances are user friendliness is not something you need.

Servers Ultimate does not require root, includes a dynamic DNS updater so your device can be found wherever it roams, and generally looks like a dream application if you’re attempting to find something neat to do with your old Android device.

Keep in mind running a server over your provider’s network may be a violation of your terms of service, so check your contract before using this. It would be a sad state of things to get kicked off your network for setting up a web page that, for example, shows the last photo you took.

While not controlled by the author, I will point out that the ad network that the developer has joined has occasionally contained some somewhat not-safe-for-work advertising, so be aware that if you’re fiddling around with the program at work an advertisement for a MMORPG with a scantily-clad elf girl might randomly appear. I don’t understand how that little chain mail is supposed to protect anything.

Servers Ultimate is available for free with advertising from Google Play, or in various forms (unlimited FTP, unlimited web, etc) for about $2, or the whole package for $6.13.
