Smart displays come in a range of screen sizes, and the smaller display on the Lenovo Smart Clock makes it a nice option for a bedside alarm clock. Today Google announced that a new update is making it an even better option to help wake you from sleep.

The new software update for the Lenovo Smart Clock adds an "Impromptu" alarm option. Powered by machine learning tech Google's Magenta open source project, this Impromptu ringtone will be customized to fit your situation based on things like the time of day or the weather. One example is that if your alarm goes off in the early morning and the weather is below 50 degrees, you may hear this ringtone.

A ringtone that can change every day and be tweaked to fit your situation could help you wake up better. Now you'll get an alarm that'll fit the time and weather rather than one that could jolt you awake, meaning your morning and your day could get off to a better start.

Also included with this Lenovo Smart Clock update is better automatic brightness, a music recommendation card that'll help you get to your playlists faster, and more granular controls over how long your alarm lasts, which can now go up to 60 minutes.

If today's update has you interested in a Lenovo Smart Clock, you can now get one for $49.99, which is $30 off its normal price. This sale price is available from Best Buy, Home Depot, Sam's Club, and Lenovo, and it'll run for a limited time.
