Description

From the listing uploaded by “appupdater”.

🎵 Tired of always being out of tune? Your violin doesn’t sound as good as it should? Ultimate Violin Tuner is a free tuner for violin, perfect for beginner violinists. By using your smartphone’s integrated mic you can tune your violin quickly and accurately. Ultimate Violin Tuner also works as a viola tuner, cello tuner or double bass tuner. Ultimate Violin Tuner is free and offers several alternative tunings for fiddle players. Everyone knows a properly tuned violin will sound much nicer. That’s why every violinist need to learn how to tune their favorite instrument. But for a proper tuning nothing can beat the accuracy of an electronic tuner, especially if you’re a beginner violin player. So before any violin lesson or practice session remember to tune your violin to get better results. With this tuning app all you need to do is choose which string you’re gonna tune or just let the automatic string detection figure it out. If you enjoy our violin tuner please feel free to leave us a review or consider buying the ad-free version! Full features ✔️ Accurate electronic tuner : professional accuracy down to less than 1Hz, you’ll never have to worry about being out of tune ✔️ String detection : you don’t have to click on any button, just play any string you want and the tuner will automatically recognize it ✔️ Easy to use interface : no complicated menu, just pick up your violin and tune it ✔️ Tune by ear : listen to any string in any tuning you want with realistic violin sounds ✔️ Sensitivity settings : Adjust the microphone sensitivity to get the best results for your particular smartphone ✔️ Change the reference frequency : if you’re bored with standard 440Hz, you can tune A4 to any frequency between 420 to 460Hz. Perfect to get that 432Hz tuning. Please be careful! If you've never used an electronic tuner before, it's recommended that you watch some tutorials on youtube first (some tutorials will be included in the app in a future release). If used improperly you risk breaking strings on your violin and that would make us feel bad :(
