Jangle is the noise coins make when they bang together, especially in a piggy bank.

Jangle is also the first ever free app, which teaches 7-11 year olds how to save money.

Quality marked by experts in financial education, (pfeg), the app allows children to create money pots to save up for things they really want. The child sets a total for the pot and then has to earn money by completing activities.

Each activity has parent notes so they can see how long it will take and what their child will learn. Parents can also create their own activities, like helping them around the house. Every time a child completes an activity they can see their money grow.

Children have their own individual logins and profiles, which they can personalise. They can also use Google search to find pictures of that must have item they’re saving for.

An early decision was taken to initially develop Jangle on the iPad. Research showed that families of young children often shared this device.

Simplicity was key in design. The app uses best in class UX principles to facilitate easy and intuitive navigation - crucial when a lot of parental approval is required. It is visually designed to be engaging for children, with primary colours, animations, personalisation and tactile elements, such as cards with turned corners, which can be easily flipped and rearranged. But care was taken that the design wasn’t too childish. 7-11 years olds don’t want to be seen as babies.

Crucial to any development was the validation by a financial expert. Experian partnered with the Personal Financial Education Group to develop all the activities on the app. Each activity was created with clear financial education goals. Goals were kept simple for children, but parents could access further information.

At launch, Jangle achieved a global reach of 1.5 billion people through PR, being picked up by national publications such as the Financial Times, Sky, and The Daily Mail. Even Lily Allen joined the conversation.

Jangle’s simple, playful design also resulted in impressive engagement figures for its many users.

As a benchmark, eMarketer research suggests the average session duration for an educational app is around 2 minutes 36 seconds. Jangle’s average dwell time is over 3 and a half times the length of this marker, with an average session lasting 10 minutes 14 seconds, with 17.08 screens being browsed per session.

Intuitive design and the logical flow through the app have similarly combined to result in consistently low exit rates (an average of 5.86%).

The app is currently only available on the iPad, but such impressive results have led to Experian now looking to invest in Android and multi device options
