Finger Shruti — Play the Shruti Box with Your Fingertips Finger Shruti is a musical instrument app that brings the mechanism and playing feel of the Indian shruti box to your iPhone. A shruti box is a traditional drone instrument that produces sustained tones by opening the reeds of the desired notes and sending air through the instrument with bellows. It is often used in Indian music, vocal practice, meditation, yoga, and sound bath settings to provide a continuous tonal foundation. With Finger Shruti, you can select the notes you want to sound and play by swiping up and down on the screen. Swiping changes the AIR value, allowing you to control the sound in a way that feels similar to operating a real shruti box. You can also select multiple notes at the same time to create richer drones and harmonies. The app supports switching between A = 440 Hz and A = 432 Hz, so you can choose the tuning that best suits your preference and practice. Finger Shruti includes a 3-minute free trial. During the trial, you can use all performance features. If you would like to continue playing after that, you can unlock the full version with a one-time in-app purchase. Whether you use it for singing, meditation, yoga, sound exploration, or simply enjoying sustained tones, Finger Shruti offers a simple and tactile way to experience this unique instrument.
