You’ll be hard-pressed to find a physical button on most Android devices, but that doesn’t mean there aren’t a legion of tactile-obsessed customers longing for one. Well, with the Dimple, you can add four of them! You simply stick it anywhere on your phone, and assign each of the buttons to a different function. It connects to your phone via NFC, and doesn’t require a battery at all. Usage scenarios could include: speed-dialing a loved one with one press of a button, launching your non-life-wasting Candy Crushing endeavour in less than 2 seconds, capturing a photo before it’s too late, etc. It’s quite useful, even if it may make your phone look just a little bit weird. And you can own one (as long as their crowdfunding goes well) for a small $27 pledge.
