* An app that sends you an alert when it’s the perfect day to eat lunch outside. (Version 2.0 could be customizable to your own preferences of temperature, sun and wind speed.)
* An app that periodically reminds you to drink lemonade during the summer. Because it’s delicious and sometimes you forget, especially because it’s not as widely available as, say, pop.
* A GPS-enabled app that tells you to bring a jacket/sweater if you are about to leave the house and the temperature is expected to drop more than 10-15 degrees within three hours of you leaving the house.
Get on this, someone.
