Nest today updated their app for Android, adding support for Rush Hour Rewards and Seasonal Savings 2.0. If you have a Nest (and are downloading this update) you probably know what these are, but for those that don't, here's the short version. Rush Hour Rewards is way to "pre-cool" your home before those times when energy demand will be high (energy "rush hours"), and can save you up to $60 over the course of the summer. Seasonal Savings makes tiny adjustments in your schedule to promote energy saving, and can deliver up to 10-percent lower costs on heating and cooling.
In addition to Rush Hour Reward and Seasonal Saving support, there are improvements to account pairing, bug fixes and better accessibility for visually-impaired users. Grab the update from the Google play link above.
