What it is
gStrings is an Android chromatic tuner that measures sound pitch and intensity for instruments and voice. It can tune violin, viola, cello, bass, guitar, piano, wind instruments, and voice, with automatic or manual target tone selection. Built-in and user-defined tunings and temperaments accommodate different setups, and users can create custom instruments. For orchestra tuning, the app can shift or redefine tone frequencies. It also includes a pitch pipe, works offline, and supports alternate tunings and a custom reference pitch. gStrings is offered as a free, ad-supported version and a paid version; the maker says both have the same functionality. The free plan is free. The maker says it does not process personal information for its own purposes, though AdMob may collect information to serve ads and share collected personal information with advertising partners.
