The beauty of the Tiltpod Mobile is that it is so simple, but so useful. This little iPhone accessory attaches to your key chain and acts as a mini-tripod to hold your phone up and in place. The base has grip on it so that it can stay stable on both rough and smooth surfaces. The mount piece is made from magnetic material that swivels and pivots on a ball head and is iPhone-safe.
Having something to hold your iPhone up is super useful. The two main uses I see are for taking pictures (especially selfies,) and for watching video, but the possibilities and uses are almost endless. The Tiltpod Mobile is available from Photojojo for just $15.
