Released in support of Queen's HIV/AIDS awareness charity Mercury Phoenix Trust, the FreddieMeter was released in honor of the band's first-ever performance of "Bohemian Rhapsody" in November 1975.
The app, developed by YouTube, Google Creative Lab and Google Research shows users how closely their voice matches one of the most iconic voices in rock history, based on pitch, melody and timbre on a score of 0 to 100.
The challenge is to sing one of four Queen hits, "Bohemian Rhapsody," "Don't Stop Me Now," "Somebody to Love" or "We Are the Champions," and get a score from the FreddieMeter.
Users can then share their score via Instagram, Facebook, Twitter or YouTube Stories and challenge three friends using the #FreddieChallenge.
The last step is to donate/encourage a donation to the Mercury Phoenix Trust.
The FreddieMeter was calibrated using Freddie's own isolated vocals, compared to people trying to imitate him. It works on desktop computers, plus Apple and Android devices.
Furthermore, the audio is analyzed by the app itself; it doesn't get uploaded to any servers, so it stays private unless shared.
The app continues YouTube's celebration of the "Bohemian Rhapsody" music video breaking 1 billion views this past summer.
