Do you think the smartphone is a source of undue stress? Try this app created by three students at the University of California-Berkeley that claims to make them a source of goodness.
The "Happyness" app is marketed as a tool to help you focus on what truly matters in life.
By tracking your moods throughout the day, the app - available now for iOS devices - can help you extract the best parts of your day, month and life.
"The app lets you rate your current level of happiness and add a journal entry to keep track of when and where you felt the best," claims the developer on their website.
After collecting the data, the app will create visualisations of your happiness ratings over time.
This cheerful piece of technology follows in the footsteps of another popular app - Happify.
Unlike Happyness (which costs just $0.99), Happify offers goals and concrete ideas to improve your mood.
Happify comes with a price tag of $69.99 for a year's subscription.
