Has one button. Hold it down to play an MLG Air Horn. Use the sliders to customize your horn's pitch and duration, even while it's playing.

Tap it a couple times then hold it down for a "Byer-byer-byer-byerrm" effect!

Not ad supported. Not collecting any data. Will never ask you for permissions. Enjoy!

Now adding watch support, which adds a button for Byerrm right on your wrist.

What’s New

Version 1.3

Addressed a crash when switching back to the app under certain circumstances, and changed the control scheme to match the watch version, which felt better! Also, the booming sound of Byerrm should now play through, even when the phone is muted.

Airhorn Throwaway ,

Simple and Byerrm

All I ever wanted was to byerrm all over the place. In my car, at work, and in the comfort of my own home. The simple design hits every one of my wants and needs; it's crisp, and leaves me with a sense of pride every time I hit the beautiful red button.

Have needed this!

Plan to use instead of applause. Kids also love it.

It is great, but if they added a complication to the Apple Watch, it would be awesome!

If they added a complication for the watch, it would be worthy of a 5 star rating.
