Windows only: For some, downloading software is a daily habit. Spot, download, install, forget. The problem is, a lot of applications don't have built-in tools for making sure they're updated. Instead of checking each program—manually—to see if it's up-to-date, run RadarSync and let it check all the apps on your system for you.
After installing and running the system scan, RadarSync highlights your installed applications that are out of date and lets you choose which updates you'd like to install. After downloading—from what RadarSync states as the official programs' servers—you can launch the install process directly through the RadarSync interface, or run it later from the saved file.
RadarSync is compatible with both the 32 & 64-bit versions of Windows XP and Vista only. It's also not the only app of its kind that we've mentioned, so if it doesn't quite fit what you're looking for, you may also want to check out previously mentioned alternatives like Update Notifier, or Appupdater.
