Clear, a simple and incredibly beautiful productivity app for iOS and Mac OS X, has been updated today with the ability to send to-do lists to another user by email.

When TNW’s Matthew Panzarino first looked at Clear on the iPhone back in February last year, he gave it a pretty glowing review. “There are apps that make you re-think the way that you’ve been using apps altogether, breaking the mold and re-forming it with just a few minutes of use,” he said. “Clear is that kind of app.”
We’re still a few years away from the self-opening home front door of the Jetsons. But that’s okay — we’re making progress. A few weeks ago we told you about Unikey and Kwikset’s Kevo, a keyless entry system for your own front door. Now the fine folks at Engadget have had a chance to work with the system hands on, and they seem to be impressed.

The system uses the iPhone’s Bluetooth LE to connect with the smartlock. Simply walk up to your front door with your phone in your pocket, tap the lock, and turn the knob. Users and security are handled via iPhone and desktop apps that allow you to share keys with family and friends as administrative, normal or scheduled users.
Having someone house sit for you? Register their iPhone with the house for the week and never worry about them forgetting to return your key. Having family come into town to visit? No need to worry about having enough house keys to go around. You can even set on-off access in case someone needs to come by, but only once.
