Spotify will be announcing news about changes in its mobile app at an event next week, according to an invite the company sent out. The event will feature presentations from chief R&D officer Gustav Söderström, vice president of product development Babar Zafar, and global head of creator services Troy Carter.

Rumors have swirled around the April 24th event since the initial invitation went out a couple weeks ago. At the time, it only instructed recipients to save the date for a news announcement, leading to guesses that it could have to do with updates to the app, or the company’s potential hardware pursuits.

Now that the new flyer confirms the event will be about the mobile app, there are a couple of options with what could be debuted. Spotify has been testing voice control with select iOS accounts, letting users more quickly navigate the app experience. Additionally, according to a Bloomberg report, the company has been working on several changes to the free subscription that will make the service easier to use, especially for those accessing it on mobile devices.
