Signal: turn your iPhone into an iTunes remote

I like Signal. Have only tried one other and wasn't impressed. Will not mention it's name. The one problem I have have with it has been the battery drain. I've found that if I leave my browser on iPhone but neglect to close the Signal tab I can almost watch my battery drain. I've had my iPhone for a while I was one of the early buyers. Only since I've used Signal have I seen such a drain on my battery although they claim it does nothing of the sort. Anyone else with this problem?

@Jon: In all fairness, Remote Buddy is NOT free. I'd be really disappointed if I headed over there, got hooked on the features (thinking it was freeware), and then ran into their $25 price.

I still think RB is more than worth the $$$, but truth is truth.

... not to forget iRed 2 (http://www.filewell.com/iRed2). Still a preview, but besides remote controlling your Mac, it also uniquely features universal remote capabilities with an optional infrared USB or LAN module.

As several people have mentioned, remote buddy does all of this for free plus much more. Remote buddy also lets you stream media back to your iphone.
Whatever company thought they could charge $25 for this should do a little market research.

If you don't have problems turning on PHP in your OS X install, you can use the free and open-source Vespasian.

I can't believe that the iPhone doesn't do this by default. Sometimes Apple's 'complete system' approach does leave a bit to be desired.

I've got an Airport Express, and I would have expected that an iPhone (or iPod touch!) would have some built-in way to send the audio wirelessly to the Express, or to remote control a Mac over wireless to do the job for it.

Shame on Apple for leaving such a gaping hole.

@Matt: Signal may be "much more slick" than Remote Buddy in your opinion, but there's NOTHING it can do that RB doesn't.

Just wanted to make sure there was a clear understanding of what constitutes "better" in the context of this discussion.

Signal's crazy-confident price point profiles their thinking that the two are similarly-equipped products. They simply are not.

i agree on the telekinesis iphone remote project. the quick way to turn your iphone into an apple remote: http://macrecon.com/five-steps-to-an-iremote/

I like Signal a whole lot and have been using it since it first came out. I've used Remote Buddy too, and that is nice for controlling a whole lot of things besides just iTunes, but for straight up controlling your tunes from anywhere, Signal is much more slick. If you have parties and use multiple Airport Express stations to bring the noise, Signal is well worth it. The interface is very much like native iPod (for iPhone/Touch) controls. Because it is a simpler UI than Remote Buddy, it works a little better for you if you've had a few pops- know what I'm saying? A nifty feature that isn't mentioned here is that Signal will retrieve album art for songs streaming over internet radio, which is alarmingly accurate. I have dedicated album art retrieving apps that aren't nearly as good at it.

I have been meaning to try Telekinesis too.

Rather..."anything on the phone that apple didn't put there"...
