LockScreen Lab is an iPhone app that lets you design custom Lock screens that can include important information like a calendar, contact info, to-do list, and your blood type. This is great for people who have a passcode setup on their iPhone, or if you just want to make it easy for someone to contact you when they find your iPhone.
There are four different types of objects you can add to your design: contact information, to-do list, calendar, and text box. For all objects you can adjust the color and opacity.
For contact information, there are 4 different styles to choose from -- two horizontal ones (one with one line, another with two), one that's a corner banner, and the fourth is actually a way to display your blood type and looks like a red liquid drop.
Text boxes allow you to adjust the font size, alignment and opacity. The todo lists are kind of neat, but you have no control over their size. There are 4 different looks for your lists: check boxes (that can be checked/unchecked), bullets, stars, dashes, and Apple symbols.
Lastly, there a four different calendars to add to your lock screen backdrop: two vertical ones and two horizontal ones.
One thing I noticed about the objects is that you cannot adjust their size. For example, in my Lock screen, I have my email address on the bottom and a calendar on the left. They are both designed to be full length/width, so the banner with my email address overlaps with calendar making it so I can't see one of the days. I'm a little OCD with stuff like this, so the overlap is drying me nuts.
LockScreen Lab is great app for creating custom wallpapers for your Lock screen. I had never considered including information like my blood type and an emergency contact, before, but since I have my iPhone setup with a passcode lock, I'm going to always make sure I include this information from now on. LockScreen lab makes this easy to do.
