I'm a sucker for a good Kickstarter project and one I recently backed was just delivered yesterday. The Keyprop attracted me because I regularly purchase cases with kickstand functionality since there are no longer devices made with them integrated into the back. I pledged $25 and ended up with blue, green, and grey/green Kickstarter special Keyprops.
The Keyprop is a simple polycarbonate device with the appearance of a key. The material has an exterior with some texture so it doesn't slide on the table and remains securely in place. The Keyprop is designed to have one of the protrusions fit into either the headphone jack or Lightning port of your smartphone with the other end resting on a table so you can prop up and use your smartphone for various reasons.
I primarily prop up my devices to watch video content, but you can also use it for reading, video calling, and self portraits. They have an iOS application, KeyCam, that acts as a self-timer for your iPhone so you can prop it up with a Keyprop and take your photo.
The Keyprop is a very simple device, yet it works as designed. I tested it with a Nokia Lumia 1020, Moto X, HTC One, Droid Maxx, and BlackBerry Z10. They all prop up securely with the Keyprop. You can rotate your smartphone or use your keys to change the angle of orientation as well. The Integral Design folks state that the Keyprop is designed to support devices that are less than 1/2 inch thick, which includes minimal cases for some smartphones.
The Keyprop is not yet available for sell, but you can visit the Integral Design website and sign up to be notified when they are ready to go. They will be available in lime green, red, blue, grey, and black. The Kickstarter price for a single one was $15 so imagine the retail version may be similarly priced.
