Sitala's already a pretty popular drum sampler on the desktop, and we've just released a version of it for iOS that's $4.99 until the end of June (after which it'll go up to $9.99).
The primary use is as an AudioUnit plugin in GarageBand, Cubasis, AUM, AudioBus, etc., but it can also be used for finger drumming, or with an external MIDI controller.
The thing people keep getting really excited about is the sample browser, which lets you browse and preview samples without importing them into the app.
You can grab it in the App Store here.
