Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users

how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About SrutiBox
SrutiBox simulates an Indian harmonium, used as a base tone in Indian music and in spiritual practices of chanting and droning.
SrutiBox 1.4 now works under iOS8, iPhone 4,5,6, and 6+ sizes, has a slightly different look, and fixes a few bugs that you may have encountered.
SrutiBox is a synthesizer, creating drones with various timbres and precise intonations that blur the distinction between tones, timbres and chords. The drone can be fairly static or undergo slow modulation and harmonic change. It now plays in the background under iOS 4.0 like many other music apps!
Pop over to http://www.jhhl.net/iPhone/SrutiBox/ and listen to some examples!
"I wanted you to know that I have made my debut in Vienna a couple of weeks ago as an iPHONEist.
I played two simultaneously - one with sruti box and the other with a variety of apps.
I am enjoying sruti box immensely! Thank you!"
— Dr. Pauline Oliveros
I also have another Droning app, Droneo, which has a similar interface, but more droning options!
SrutiBox uses 12 "reeds" which can be tuned to a great number of scales, randomly detuned, and chorused and modulated. The pitch interval and volume of each "reed" can be set individually, making for a wide variety of drones. The reeds can be set to various timbres suitable for drones, including vocal-like timbres and low frequency-friendly chirps.
A special iPhone feature of SrutiBox is that you can wave the phone in an imitation of pumping the bellows, adding a touch of realism to the simulation.
SrutiBox can also be used as a pitch source for instrument tuning purposes, or as an aid for learning the difference between Just and Equal Tempered intervals.
As with other iPhone/iPod touch audio applications, it'll sound better through headphones, although in a quiet room, it's quite effective! Make sure to use the volume controls on the side of the phone to set the volume level you like.
