We've seen a few Android-based image flashing tools in the past. These tools, such as XDA Elite Recognized Developer Chainfire's Mobile Odin (thread), allow us to sidestep the traditional inconvenience of having to take our device offline in order to perform certain flashing tasks. Instead, they allow us to flash from within the Android UI itself. Chainfire's offering, in particular, is rather interesting because you can inject MobileOdin and Superuser, as well as flash entire firmware packages, radios, and more from within the app's UI.

It's always good to see other options pop up, and one such option comes from XDA Recognized Developer frapeti. The app doesn't flash entire ROM packages or radios. In fact, it only flashes kernels. However, it has a very streamlined user interface and gives extensive feedback throughout the entire process, including preventing you from flashing an incorrect kernel and a readout on the to-be-flashed image's MD5sum so that you can verify that the image is uncorrupted.

Similar to the aforementioned complete firmware package flashing tool Mobile Odin, Universal Kernel Flash Tool does not increase your flash counter. Currently there are four officially supported devices, but many more devices will inevitably work. However, if you're trying this on an unsupported device, do yourself a favor and make a full Nandroid before proceeding and be ready for the unexpected in case something does go wrong.
