Tuba Fingerings is a free Android app developed by Torkex Apps that provides a comprehensive guide to fingerings for BB, CC, E, and F Tubas. The app includes fingerings for both 3-5 valves, non-compensating and compensating, and represents piston valves or rotary valves. Additionally, the app offers sound clips for each note from F1 to F4, which is best experienced through earphones or loudspeakers as most phone speakers do not project bass sounds well.

The app also includes basic language support for French, German, Italian, Spanish, Portuguese, Korean, Japanese, Russian, Turkish, and Simplified Chinese. Furthermore, note names are available in English, Northern Europe, and Neo Latin.

Overall, Tuba Fingerings is a simple and user-friendly app that provides a useful guide for Tuba players.
