Our task was to develop an app on which you can tune an electric guitar, an acoustic guitar, a bass guitar and a ukulele. The app is suitable for both professionals and amateurs. The tuner works smoothly, accurately and without jerking which most apps have. The application can be seen from a distance because it has a contrast interface. There is an opportunity to apply different tunes in each tool. There is a tuning fork for setting the instrument by ear.
