Say you’re a 12 year old girl and you want to keep a diary. Not that long ago, you might’ve put pen to paper and kept that little book under a pillow in your room, protected by nothing more than a ceremonial lock. In the iPad age however, it’s far more likely you’re going to go digital, but let’s face it, that tablet isn’t going to stay under your pillow. To keep your private diary private, the iHeart Locket uses a smart pendant as the locking mechanism for its iOS application. This pendant emits a unique audio chirp that both locks and unlocks the app. It’ll work with only one pendant, but if you lose it… you can always enter a 4 digit code to gain access again. Still, the notion that there’s a physical “key” that opens the diary could be appealing to the product’s target market.

The app itself allows you to add photos, illustrations, digital stickers and audio recordings, all scrapbook-style. There’s even “an automatic transcription function (powered by Nuance Communications) for those who are too young to type.” It’s altogether not a bad feature set for $25, and if someone’s birthday is coming up, could make for a decent present.

Or they’ll just think you’re cheesy, old and outdated and never use it. There’s no understanding kids.
