No matter what service you build on, or who your audience is, Amazon has the tools and services that will empower you to build a great app. By using Amazon's developer portal, you can distribute your mobile apps, digital software and web-based services—to tens of millions of Amazon customers. You can also sell your mobile apps on Amazon devices, like Fire TV or Fire tablets.
Amazon pays developers 70% of the list price for all sales. The programme is free. You pay nothing to create a developer account, use Amazon APIs, and submit apps. And you'll be adding your app to a very active marketplace—the Amazon Appstore now has over 400,000 apps and games, is available in over 230 countries and territories, and on a multitude of devices.
