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 visualizations 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 USD 0.99), Happify offers goals and concrete ideas to improve your mood.

Happify comes with a price tag of USD 69.99 for a year's subscription.
