MacUpdater is an application that can scan your Mac and display which of the apps that you have installed are not up-to-date. MacUpdater can also update those outdated apps to their newest versions with a simple click. MacUpdater can silently run in the background and check your apps for updates every day and let you know with notifications once a new update is available.
SMARTReporter is an application that can warn you of some hard disk drive failures before they actually happen! It does so by periodically polling the S.M.A.R.T. status of your hard disk drives. S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a technology built into most modern hard disk drives that acts as an "early warning system" for pending hard disk drive problems.
UninstallPKG is an application that allows you to completely remove/erase/uninstall so called "packages" (file-extension: "pkg") and all their installed contents from your Mac. UninstallPKG can be also used to reclaim precious disk-space by removing unwanted functionality like unused printer drivers or clean-up your Mac by purging apps that you have already partially removed manually.
SSDReporter is an application that checks the health of your internal Solid State Disks ("SSD" aka "Flash Storage"). Since SSDs have a limited life-time determined by the number of write operations it's important to keep an eye on your SSD status. SSDReporter can warn you by e-mail or on-screen when the health of your SSD decreases and displays current status via its icon (Dock or Menubar).
