Three free remote-access apps for iPhones

The App Store is home to numerous apps that let you connect to a desktop PC from afar. Granted, navigating Windows on a screen as comparatively tiny as the iPhone's is not a lot of fun, but it works better than you'd expect.

TeamViewer brings powerful remote-access features to your iPhone, yet it doesn't cost a dime.

Indeed, I've used remote-access (or "RA") software many times for simple tasks like e-mailing a file, peeking at a document, and even shutting down the PC (when I'm too lazy to walk down a flight of stairs).

My RA app of choice? LogMeIn Ignition, which works even better on the iPad than it does on the iPhone. Just one problem: it costs $29.99. (Ironically, the required desktop counterpart, LogMeIn Free, costs nothing.)

Thankfully, I've found a handful of free RA apps. (There are others, but I'm focusing on the three I know best.)

First up: RDM+ lite, a new, ad-supported version of the $9.99 full version. (For the same price you can buy the iPad version.) RDM+ is noteworthy for supporting both Mac and Windows systems--you just need to download the proper desktop client.

Next, there's JumiMouse, which in its early days merelyturned your iPhone into a touch pad, but has evolved into a more complete remote-access app. The free version is a bit limited in that you can't interact with your PC when you zoom in at all (which is quite necessary for most functions). Thankfully,JumiMouse Plus costs just $1.99. Note that this one's Windows-only.

Finally, my favorite freebie: TeamViewer, a full-featured, Mac/Windows-compatible remote-access app. It has no ads and no limitations to speak of. Plus, it did a better job on my iPad than either of the other two apps--though pixel doubling is just no substitute for an HD version.

Well, those are my three freebies. Have you found another free remote-access app you like better? Or at least one that doesn't cost 30 bucks?
