Attach the iHere 3.0 to you keychain or pop it in your wallet (it's the size of a large coin), and you'll be able to track its signal with up to a 75-foot radius using the smartphone app. There's even an option to set a separation alert for your phone if you're prone to misplacing it. Best of all for the forgetful, you don't have to remember to charge it often - a single USB charge lasts up to several weeks.
