Some people invent new things just because they can. Take for example Scentee: an app from ChatPerf that lets your smartphone emit odors. Yep -- we're about to be bombarded by strangers' phone smells, on top of their cologne.
The app uses a small accessory that you plug into your iPhone or iPad, giving you access to more than 500 different smells, ranging from the delicious (bacon) to the disgusting (durian). It's like augmented reality for your nose; we wouldn't be surprised if certain iPad games start incorporating sense-based "experiences" like this.
The Scentee app will be available in August, and its hardware accessory will retail for $30. Happy smelling!
