Launched in 2010, Soundtracker by South Ventures USA, is described as an app that allows music to connect people by making it easy to discover and play music in real time with friends and anyone nearby. With Soundtracker you can create stations, chat with other users, listen and comment on their latest stations amongst other features. Available on the Amazon Appstore here as well as other platforms, Soundtracker has over 4 million downloads and 1 million active users worldwide across all platforms.
I had the chance to sit down with Daniele Calabrese, CEO and founder, to discuss their experience bringing Soundtracker into the Amazon Appstore and how they’ve managed to leverage different Amazon Mobile Apps APIs to their advantage.
Even though the app itself is available on various platforms, the reason why Daniele decided to bring the app to Amazon Appstore was simple. The “opportunity with Kindle was too good to pass on since we would be able to create an app for two platforms at once.” Daniele says that early on the team realized that the Android SDK was compatible with Kindle Fire, so they decided to build the apps in tandem. The team found out quickly that “the process in getting Soundtracker into the Amazon Appstore was very easy and the results from it has definitely paid off.”

Besides using Amazon’s In-App Purchasing and Mobile Ads API, Soundtracker also uses Amazon’s Maps API and Device Messaging API as well. For Soundtracker “being able to monetize and engage your users are the most important factor in choosing a platform” says Daniele. The team credits these specific API’s as “the reason why we were able to be so successful in the Amazon Appstore.” By integrating certain APIs you can also qualify for different programs. Daniele says the team is “excited to be admitted into the Appstore Developer Select program,” which provides the team with 500k mobile ad impressions, Amazon Coins rewards to customers, and more.

Since Soundtracker detects where other users are, relative to their current location, notifying other users who are nearby is crucial for engagement. The team decided to use Amazon Device Messaging API and Amazon Maps API to help solve this issue. The device messaging and maps APIs allow users to really engage by integrating interactive maps directly into your app, as well as sending out push notifications from the cloud to the user. When your app relies heavily on social interaction, such as Soundtracker’s feature of commenting or discovering other users’ playlist selections, getting a user’s attention is one of the most important factors. By using these APIs, the team was able to see a consistent lift in engagement.
“Engagement in the Amazon Appstore increased by 400% in the last 6 months. Number of sessions, length of sessions, and number of tracks streamed per user increased on a weekly basis.”- Daniele Calabrese
So how long did it take for the team to integrate all these APIs? Daniele says “the process for development and testing altogether took only a week and the process was very straight forward”.
According to Daniele, “since performance has been successful with their current app on Kindle Fire” the team plans to expand even more into the Amazon ecosystem. The next step for the team is “integrating with Amazon’s music offering and getting their app on Amazon Fire TV.” Since the team has already qualified for Appstore Developer Select, the team can now qualify for the Appstore Developer Select Amazon Fire TV benefits as well by optimizing for the Amazon Fire TV. This includes enhanced on-device merchandising and a 500k Amazon Coins offer per qualifying app.
“I would recommend Amazon Appstore to other developers. Getting our app on Kindle Fire was very easy and it gives developers a great opportunity to distribute and monetize their apps.” – Daniele Calabrese
