It still works, press the button to remind you of South Africa 2010, but I really don't know why they added these horrible features. ### 3/5 — $99.99????!!!!! *2010-11-18, version 0* This has to b a mistake for the full version. Who in their right mind would pay this much for such a lame app??? ### 1/5 — Ight *2010-10-26, version 0* Can't belive they charge 100 bucks for full app hahaha FAIL ### 5/5 — The best Vuvuzela App ever *2010-07-13, version 0* Thanks. ### 1/5 — Eh *2010-07-08, version 0* It makes the same sound the other vuvuzela app makes N with the other one u can change colors of the vuvuzela so it's pretty lame...smh ### 5/5 — Awesome! *2010-07-08, version 0* Just needs to be constant. ### 1/5 — Horrible *2010-07-07, version 0* ^^^^^^^ ## Frequently asked questions about Diabolica ### What is Diabolica?
