Well, my all time favorite vertical shmup is Shogun: Rise of the Renegade.
After that, it's Bug Princess by Cave.
My second favorite Cave game is Espgaluda II.
If you want something a bit more casual but very fun check out Zombie Bunnies. It's actually the only horizontal shmup (with relative touch) that I can get into on iOS.
I'd also highly recommend Beat Hazard Ultra. It's probably the most popular casual shmup on iOS. It's the one where music controls the gameplay. Don't worry about not having music either because there's Internet radio on it.
The last two I'd really recommend are Space Tripper (horizontal w/ tilt controls) and Bug Panic.
