DroiDrum is a free Android app that lets you play the drums on your mobile device. It is developed by HIROMARU KOBO under the multimedia category and is suitable for music and radio enthusiasts who want to try their hand at playing the drums.

DroiDrum is packed with features that make drumming on your mobile device an enjoyable experience. It supports multi-touch, size and position change, volume adjustment, playing with motion sensors, screen slide, and has animations when playing drums. You can also adjust the L/R audio balance depending on the location of the drum.

It is important to note that DroiDrum is best enjoyed with wired earphones as the Bluetooth earphone sound reproduction is delayed. If you are using "Samsung Galaxy S," it is recommended to update to Android OS 2.3 for improved response. However, if you want more features, you can check out the paid version, "DroiDrum Pro."
