HyperJar is a money management app and prepaid debit card that aims to simplify saving and spending. The app allows users to split their budget into different "Jars" and spend directly from them. It also offers joint accounts and shared spending options through Shared Jars. In addition, users can access discounts on popular brands through the app's Shops tab. HyperJar is compatible with Apple and Google Pay, making it convenient for users to make payments. The app also offers a Kids Card, which is free and allows parents to monitor their children's spending, set limits, and block specific shops or services.

HyperJar provides additional tools to help users organize their finances effectively. Users can schedule payments into their Jars and link specific shops to their Jars, ensuring that money is automatically deducted from the appropriate Jar when making purchases. The app also allows users to create "Only and Never lists" for each Jar, enabling them to control where their money can be spent. HyperJar offers a secure platform, with features such as the ability to freeze the card, check the PIN within the app, and bank-grade encryption to protect user data and money.

The app has received positive reviews from customers, with many praising its user-friendly interface, lack of hidden fees, and excellent customer service. Users have found HyperJar to be a great alternative to other similar apps, such as GoHenry, and have appreciated its ability to help them budget and track their spending. HyperJar has been recognized with awards, including Personal Finance Tech of the Year at the UK FinTech Awards and Money Management App of the Year at the Payments Awards. The app can be linked to various banking apps, allowing users to deposit money into their HyperJar Wallet from a range of banks, including Barclays, HSBC, Revolut, and Monzo.
