Amazon Creator helps you bring your video content into the living room of millions of Amazon customers who consume video through Fire TV.

Note that apps created using Amazon Creator are required to be free.

Each section or category is automatically listed in the navigation menu in the app. Here's what the Default theme looks like:

Apps you create are available in all regions where Fire TV is available — United States, United Kingdom, Japan, Germany, Austria, and India.

500px x 500px size image for your logo.

Amazon Creator has a 2MB file-size limit on uploads. To upload 1920px x 1080px screenshots, you will likely need to use JPG images (instead of PNG) and maybe some compression.

promote your app in the Fire TV Appstore and the Amazon Appstore website. If your image isn't the right size, the image will be scaled up or down by Amazon Creator to fit the right dimensions. However, note that scaling images up makes them fuzzy, and if the aspect ratio isn't correct, the image will be stretched or squished, so use the correct dimensions.

114 x 114px (small icon)

and

512 x 512px (large icon).

Both are used to represent your app throughout the Amazon Appstore and on Amazon devices, so use high quality images. The small icon can be a simplified version of the large icon's design that looks better in thumbnail size, or both icons can simply be the same design. The icons will be scaled down to a smaller size.

Design Best Practices

DO:

Use original assets. App icons should reflect original graphic assets related to your app.
Use contrast. Contrast will make the app icon distinct even when it is scaled down.
Use balance. Use imagery that has a sufficient amount of white space.
Use fewer subjects. Fewer characters in app icons is preferred.
DO NOT:

Use wrong assets. There should be no marketing slogs or studio badging. Only logos or key art.
Make it illegible. Do not overlap logos on major characters or on a busy background.
Apply wrong styling. Key art should go to the edge of the image. Do not include borders or rounded corners.

Fire TV App Icon
The App Icon appears within a row of other app icons in the Fire TV user interface.

Detail Requirement
Size 1280 x 720px
Format PNG (no transparency)

To ensure your App Icon looks good even with badging (download icons, progress bars, etc.), place your main subject and title art within the content safe area. Artwork that falls outside of the safe area may be covered by badges.

If you don't provide the required Fire TV assets, Fire TV will apply a default creative treatment to the images to scale them to fit the required spaces. For example, if the required image size isn't proportional for the required space, your image will be placed on top of a background image that fills the space correctly.

When users scroll across your app from a browse page, the Background Image appears in the upper-right corner of a mini-detail page.

Detail Requirement
Size 1920 x 1080px (landscape)
Format JPG or 24-bit PNG (no transparency)
The following is an example of a Background Image:

When users click your app icon, the Background Image can also fill the entire background.

Design Best Practices:

DO:

Use cinematic imagery. Use imagery that is engaging and has a pleasing composition.
Use relevant imagery. Use imagery that is relevant to the app experience. Don't show a person using the app, the controller, the TV, or the surrounding room. Just show the app itself.
Use different imagery. When possible, use different imagery than the app icon.
Use character-centric imagery. Use imagery that includes major characters or notable content.
Place subject right. The main subject should be to the right side of the image when possible.
DO NOT:

Place subject left. The main subject should not be on the left side because the UI may obscure it.
Crop heads and faces. Use the safe zones to verify placement of heads and faces.
Embed logos or titles. Logos and titles should not be in the background.
Use busy imagery. Do not use imagery that has too many subjects or fine detail.
Show other platforms. Amazon Appstore offers many apps that also exist on other platforms (smartphones, tablets, competitor devices). Assets should reflect the experience of the app on Fire TV.
App Descriptions Required

Screenshots
Screenshots show images from your app to give users a better sense of what your app offers. Include a minimum of 3 and a maximum of 10 screenshots. For details on taking screenshots, see Taking screenshots on Fire devices.

Specifications:
Detail Requirement
Size 1920 x 1080px (landscape)
Format JPG or 24-bit PNG (no transparency)

App Descriptions Required
A short description of your app that is appropriate for display on a TV or tablet device. The maximum length is 1,200 characters, but consider using a shorter description. (Paragraph breaks get stripped out.) The Fire TV UI displays displays only the first 200 characters, then shows an ellipses to read more. Optimize your short description to include the most important information up front.

Long Description
A lengthier description of your app that is appropriate for use on the Amazon Appstore website. The maximum length is 4,000 characters. The long description appears in the Appstore website only, not on tablet or Fire TV devices. Note that all text input fields (including the short description and other fields) are plain text only. Do not enter HTML markup (it will fail testing and delay your app's publishing).

Product Feature Bullets
Three to five key features of your app, one feature per line. Press Return after each feature. Each line will automatically be converted to a bulleted list item when you press Return.

Keywords
Comma-separated search terms that will help customers find your app in the Amazon Appstore. These keywords can be helpful in surfacing your app when users search Fire TV, either by text or with voice.

Subject Matter
All apps published to the Amazon Appstore must adhere to the Content Guidelines that are described in Amazon Appstore Content Policy Requirements. If Amazon determines that an app contains, facilitates, or promotes content that is prohibited by these guidelines, Amazon will reject the app submission or suspend further distribution of your app and notify you at the email address associated with your developer account.

Warning: Most apps that fail the Appstore review process fail due to content policy violation. You must own the rights to the content in your app. You cannot create apps from YouTube channels that you do not own. If you do not own the content, your app will fail the Appstore evaluation process. Even approved apps can be retroactively suppressed.

Family-Friendly Environment: Always keep in mind that the Amazon Appstore is a family-friendly environment. If your app contains content that would not be considered "family-friendly" and does not have adequate safeguards in place for our young customers, your app will be rejected or suppressed from the Amazon Appstore. See also Restricted Content Policy.
Offensive Content: Use common sense in determining whether your app contains offensive content. Amazon reserves the right to determine the appropriateness of all apps and to accept or reject any app at our discretion. Amazon also has discretion to determine the appropriate content ratings for the apps. See also Restricted Content Policy.
Pornography: We prohibit apps containing pornography or that depict sexual acts or sexually explicit material. This includes nudity contained in your app or marketing materials. We also do not allow content that drives traffic to adult sites. See also Restricted Content Policy.
Illegal Activity: Each app must comply with all applicable laws. We prohibit apps that promote or may lead to the production of an illegal item or illegal activity. Developers are responsible for researching to ensure that each app is in compliance with all local, state, national, and international laws. See also Restricted Content Policy.
User-Generated Content: Apps that include, or link to, user-generated content must include a method for filtering objectionable content, an age verification system, and a mechanism to report and remove offensive content. See also Restricted Content Policy.
Malicious Behavior and Security Violations: Your app cannot include or contain instructions for malicious hacking, such as phishing or Trojans, or contain cracking content in the app or app metadata. This includes but is not limited to rooting a device, circumventing Amazon's or any developer's digital rights management (DRM) software, and illegal torrents, emulators, and downloaders. See also Privacy and Security Policy.
Real-Money Gambling, Gaming and Competitions: Subject to meeting our requirements, we allow certain apps that facilitate or enable gambling, gaming and competitions with real currency (currency with actual monetary value). See also Restricted Content Policy.
Intellectual Property Infringement: Apps that infringe the intellectual property rights of a third party may not be distributed in our Program. See also Intellectual Property, Deceptive Behavior, and Spam Policy.
Privacy/Publicity Infringement: Amazon holds personal privacy in the highest regard. Therefore, Amazon prohibits apps that infringe, or have the potential to infringe, upon an individual's privacy, right of publicity, or that portray an individual in a false light. Celebrity images and/or celebrity names cannot be used for commercial purposes without permission of the celebrity or their management. This includes unauthorized celebrity image collections. See also Intellectual Property, Deceptive Behavior, and Spam Policy.
Country or Region-Specific Restrictions: Some countries or regions in which we sell our apps may have more restrictive standards than other countries or regions for what qualifies as "Offensive Content," "Pornography," or "Illegal Activity." Amazon may restrict any app or IAP item from sale in any country or region where the sale or distribution of that app's content would violate that country or region's laws, cultural norms, or sensitivities.
Amazon does not proactively approve apps prior to you submitting your app. All apps are required to go through the app submission process to be published in the Amazon Appstore.

Amazon reserves the right to make the final determination on what apps are available in the Amazon Appstore, and which integrations are enabled for partners. Factors we consider include compliance with the Amazon Appstore Content Policy, as well as ensuring relevant selection in the Amazon Appstore, bugs which may degrade the customer experience on Fire TV, and risk of abuse or customer harm.
