When it comes to beautifying your phone, most of the options involve complicated modding procedures, installing sketchy software, or spending entirely too much time shuffling through configuration screens. Sometimes, all we need is a low maintenance option that does the hard work for us. To that end, Sparky Lock Screen is determined to deliver an ultra-fast, incredibly simple lock screen replacement that looks great without making you work for it.
Simplicity is obviously the driving force behind Sparky. There is but one option: which theme you want to use. That's it. No extended configurations, no toggling of checkboxes, no picking through pages of background images. Each theme is designed to play to the strengths of its imagery, so unlocking might be achieved by tearing the bottom of a ticket or sliding a dial to start the messaging app. You can test each lockscreen before choosing, which presents a brief instructional screen to show off the capabilities within the scene. The total lack of extensive configuration options may not appeal to the hardcore theming crowd, but that's not the goal here; it's about having a set-it-and-forget-it experience.
Sparky Lock Screen is currently only supported on phones, but judging by the Play Store description, a jump to the big screen is probably forthcoming. The graphics are crystal clear on my Nexus 4 and HTC One, and everything runs very smoothly. A lite version is available to try out for free with two sample themes: the Donut and Sketchy (1st and 2nd screenshots above). The full version can be had for $1.99 and delivers all 8 scenes. If you feel like a change of pace for your lock screen, this one is definitely worthy trying out.
