Is there any app costing 47p or less?

Yes, there are apps available for 47p or less, particularly in app stores like Apple’s App Store or google Play Store. Many developers offer promotions or discounts, and there are often apps in the categories of games, utilities, or productivity that can be priced at or below that threshold. However, pricing can vary by region and over time, so it's best to check the app store directly for current offerings.
