About
FXST turns any sound into a reaction you can send in Messages , no more typing "lol" when a laugh track says it better.
Record or import
Record your own voice, or turn any video from your library into a sound clip. Trim it, add pitch and reverb effects, and it's ready to send.
Send it like a real reaction
FXST sounds show up right in the Messages transcript and play automatically, no extra taps for whoever you send it to, even if they don't have the app yet.
Browse Community
Discover sounds shared by other FXST users, preview them before you save, and check what's Trending. Share your own favorites back.
Make it yours
Give any sound its own cover art. Pick from a set of designs or upload your own photo.
Built for speed
Favorites, recents, tags, and search keep your most-used sounds one tap away, right from the Messages app drawer.
