Everything You Need
Powerful features built for hunters who take their calling seriously.
Sound Library
Import, organize, and manage your entire sound collection in one place. Smart filters let you browse by category, brand, favorites, and recently added. Create custom folders, star your go-to sounds, and always know exactly what you have.
SD Card Management
Plug in your SD card and see everything at a glance. Drag sounds between folders, rename, reorder, and manage your caller's card without touching Finder.
Smart Categories
Automatic categorization by species - Coyote, Fox, Rabbit, Fawn, Bird, and more. Filter by sound producer like Tony Tebbe, Boss Predator Acoustics, or Bustin Fur Audio.
Audio Preview
Preview any sound before copying it to your card. Built-in waveform player with scrubbing so you know exactly what you're loading.
Safe Card Writes
Every file written to your SD card uses hardware-level sync (fsync) to prevent corruption. No more lost sounds from unsafe ejects or interrupted transfers.
Folder Organization
Create, rename, reorder, and organize folders right from the app. Drag-and-drop reordering with save and discard controls makes card setup fast.
