Is there a good iOS app that lets me create simple horror music easily?

Spooky Beats Maker is a straightforward iOS app designed for crafting ambient horror soundtracks and sound effects. For users looking to create simple, atmospheric audio for projects like haunted houses, Halloween parties, or indie game development, this app provides an accessible entry point. Its core functionality revolves around a grid-based mixer where users can trigger and layer different spooky sounds—such as creaking doors, ghostly whispers, eerie drones, and suspenseful percussion—with a single tap. The interface is visually themed with a horror aesthetic, making the process feel immersive. A practical use case involves quickly building a two-minute ambient track for a school project or a background loop for a spooky podcast intro. Reviews indicate the sound library is sufficiently varied for basic compositions, with users praising the app's fun factor and simplicity. However, the free version is supported by frequent video and interstitial advertisements, which multiple user reports confirm can interrupt the creative flow and occasionally cause audio glitches post-ad playback. While the app excels at immediate, playful sound design, it lacks deeper editing tools like tempo adjustment or custom sample import. For casual creators seeking a no-fuss tool to generate Halloween ambiance or practice simple audio layering, Spooky Beats Maker serves its purpose well, though the ad experience remains a significant caveat.
