Amazon has added the option of charging for HTML5 web apps on Amazon Appstore and HTML5 developers can now take part in Amazon’s Free App of the Day (FAD) promotion.

The Amazon Appstore has accepted HTML5 apps since August 2013. However, until now, if you published a web app to the Amazon Appstore it was automatically set to be free for download. The change means you can set a list price in specific currencies based on the local markets in which you’re publishing your web apps. The change can be applied to existing apps that you’ve already published; all you have to do is to log in to your Developer Account to see an updated “Availability & Pricing” tab with the option to charge for the app.

The change also means HTML5 developers can take part in Amazon’s Free App of the Day (FAD) promotion. If you’re not familiar with this, the way it works is that for one day only your app is publicized as being free to download for that day, gaining greater exposure that could drive significant traffic to your apps.

According to a blog post by Jesse Freeman about the change on the Amazon Developer Console:

“Opting into the FAD promotion and being selected enables us to work directly with the publisher to be featured in some of our most visible marketing placements. This includes placements on mobile devices, Kindle Fire, and the Amazon Gold Box Best Deals page, which are complemented by social media exposure including Facebook and Twitter announcements. These placements and the exposure they provide can drive significant traffic to the featured apps and allow the developers to grow their install base quickly.”
