iTrumpet
$0.99 from idvance LLC 
We at idvance LLC are proud to introduce version 2.1 of iTrumpet. iTrumpet is for people who play “real world” trumpets, not for the casual gamer:
A. iTrumpet does not require you to blow into the iPhone microphone! You blow a real trumpet using a range of mouth positions. We have deliberately chosen not to require confusing alternate behavior for your lips and tongue - we see blowing into the iPhone microphone as an awkward gimmick, not as a practical design point.
B. iTrumpet does not require contrary fingering! You play iTrumpet like a real trumpet, using your right fingers to press keys. To control embouchure, and to get open notes, you use your left thumb - which is idle when playing a real trumpet.
C. iTrumpet simulates a B flat (transposing) trumpet with a full three octave range - and with respectable sound quality for a simulator.
We design and test iTrumpet with experienced trumpet players. We believe that if you are a student or a professional musician, you will find our solution most compatible with how you play your real world instrument. If you are in a marching band or a jazz ensemble, give iTrumpet a try. Then email us at info@idvance.com, and let us know what we can do next to make it even less of a crude alternative when your primary instrument isn’t handy…
