I can see there's quite a lot of scope to delve into as well. This is definitely one for people who like experimental music, however, it can be used effectively in a subtle way to add a bit of depth or undercurrent to strings, for example. The sound is good and the layout is nice and user friendly . There are music apps that offer much more singing and dancing, but this one goes a bit deeper. Well done! ### 4/5 — Quirky, But Enjoyable Program *2011-02-22* Sadly it seems Mr. Lowengard is focusing on Droneo, but the srutibox is fun and *CAN* sound wonderful, if you're willing to play with the settings. I use a variety of noisemakers at night to help me get to sleep, and the problem with most of them is that they offer only a limited set of preprogrammed sounds. I enjoy the variety and customization that srutibox provides. Although a built-in sleep timer would be wonderful, you can use your ipod/iphone timer instead. Get this if you like drones and aren't afraid to fiddle and knobificate! ### 4/5 — Ugly Box, Sweet Filling *2009-05-15* I bought this after listening to the audio examples on the developer's site; it makes a surprising variety of timbres, and with the Churn feature, you can crossfade between any two for an animated sound. It's a lot deeper and sweeter-sounding than it appears from the drab Formica interface. I'm enjoying exploring alternate tunings and learning how harmonics layer to form chords and textures. I don't like the clicks you hear when changing some settings, and I told the developer an echo effect would make the drones even spacier, but he replied that would detract from the authenticity. (Bonus points for responding at length to my emailed suggestions!) He also said he'll be concentrating on his Droneo app, so I'll probably buy that next. ### 4/5 — Very Cool *2009-02-18* If you know music theory, you can have a ball with this. I was originally looking for something that could emulate a Tanbura. This gets close, with the right scale, but it could use a preset voice for the Tanbura, and something to distort the waveform to get it to sound like a Tanbura drone. I realize that it wasn't intended for that, it is a SrutiBox simulator, but it seems like it wouldn't take much to add the Tanbura, and it would make it much more useful (at least for me). Still, think it is a great app. ### 5/5 — Never thought I'd see something like this on the iPhone! *2009-01-04* Simply brilliant, unlikely to appear on any official "most favourite app" list, but brilliant nonetheless! Great new update with basically all the features I wanted without even telling anyone. The developer must be psychic too! :-) ### 5/5 — Amazing App. *2009-01-01* Thank you so much for Sruti Box. In addition to being able to adjust notes from the harmonic series, it also gives you the ability to play notes in a variety of tunings, as well as create your own! An amazing instrument and learning tool for musicians of any level! -michael Uhler ### 5/5 — I Dig It *2008-11-09* Its fun to have something like this if only to manipulate interval and chord tones against each other on your ipod at your convenience. I think the haters that are whining about the 3 bucks and I should have used logic and all of that are missing the point completely. The sounds are soothing and pleasant enough even if they are not totally authentic, and kind of remind me of some of the non-westernized pedal tone drones used on some of the recordings I have from people such as Ustad Bismillah Khan. ### 5/5 — Dronetastic! *2008-11-02* If any iPhone app is going to make it on to the next Nurse with Wound recording, it'll be this! ;-) SrutiBox is NOT for the fainthearted. Don't buy this app if you like R&B, boy bands, or naff pop Muzak (unless of course, you're on acid!) SrutiBox is like having Ligetti in your pocket, ie a truly weird sound creation app. Therefore SrutiBox comes highly recommended! ### 4/5 — Great App. *2008-10-16* I really love this app. as a sound source, AMAZING to feed into my DAW and further process, essentially using it like an instrument. 1 small improvement - when moving the different pitches/tones sliders on and off there is some small audible glitch like sounds that come out in all of my recordings ### 4/5 — Great app, but I need some help testing something *2008-10-12* Is the new version causing anyone else's iPhone to overheat and stay overheated until the app is uninstalled? I had this installed for a couple days before I tried it. After trying it, I didnt notice anything odd, but a few hours later my iPhone felt really warm. I thought it was a body heat thing, since the phone was kept in an inside coat pocket. But the temp never dropped, even when I kept the device off-charger and near a fan. At some point I recalled that v1.0 of Sruti mentioned slight heating while Scrutibox was played...I guessed that maybe some function in version 1.1 wasn't releasing all of its resources, and this was causing some sort of runaway heating...to test this, I uninstalled Srutibox. I noticed almost instantly that my iPhones temp was normal. Has anyone else experienced this? This is not a knock on the app at all...I really enjoy it and wish I could find a way to port the sound to my Boss BR-600...but I can't play it if it's going to overheat my phone. ### 4/5 — awesome *2008-10-07, version 0* Thank you for this app! Please continue to support it. I love using it at gigs as a backup drone, and I'd love to see added functionality. Maybe a stereo reverb setting to amp up the room wetness? ## Most critical reviews (10 lowest-rated) ### 1/5 — Don’t buy/ doesn’t sound like sruthi box *2022-04-25* This app is useless, doesn’t sound anything like harmonium or sruthi box, doesn’t have intermediate tones like G# and is complete waste of your money. Their website link for information is not working either ### 1/5 — Not a Shruti Box *2021-05-02* Not user-friendly interface and doesn’t sound like Harmonium or Shruti box at all. Don’t buy it. ### 1/5 — Pathetic *2021-03-06* Just won’t play at a acceptable volume level with out external amplifier. Not a mobile solution ### 1/5 — Stupid App!!! Waste of $$$ *2020-11-03* Doesn’t sound at all like a Shruti box. COMPLETE RIP-OFF!! ### 1/5 — Not satisfied with the sound ... *2018-03-10* The sound produced is not similar to a Shruti box. I am disappointed with the purchase. ### 1/5 — Gopal *2013-05-17, version 1.3* I am not sure if the programmer tried once. Most useless I ever bought, minimal criteria for this program is sound, which I don't get it. Apple should remove from its site. ### 1/5 — Dew dew *2011-01-13, version 0* Sounds are very very bad. Waste of money. Should be marketed as a simple multiple sine wave generator. ### 1/5 — Inutilisable, très mauvais, à éviter *2008-12-19* Deux choix, soit vous n'utilisez que les sons sinusoïdaux purs, et alors vous obtenez un son horrible, insupportable au bout de quelques minutes (mais c'est accordé). Soit vous utilisez les quelques outils fournis pour rendre le son plus doux, mais alors là, c'est totalement inutilisable, tellement c'est désaccordé. A éviter absolument si vous voulez faire de la musique ! Au fait, ce n'est pas un harmonium comme certains le disent dans les avis avec beaucoup d'enthousiame... ### 1/5 — Not even close *2008-09-13, version 0* I have a harmonium, and have use a shruti box many times. for those of you thinking you're going to get the deep responant, reedy tones of a shruti with this app.... SORRY! Like on of the other reviewers has said, and I didn't listen. It's a tone generator. ### 2/5 — バックグラウンドでバッテリー浪費 *2023-04-13* 微分音の和音の検討に使用可能。…しかし、なんかバッテリーの減りが早いなと思っていたら、バックグラウンドで謎の処理が継続されていた。マイニングとかに利用されてないだろうな？？使用後はタスクキルが望ましい。 ## Most praised reviews (10 highest-rated) ### 5/5 — 👍👍👍 *2020-10-31* I have been using this app for years. Love it. Dr. Pauline Oliveros?! That’s high praise. ### 5/5 — great app...a must have *2015-04-21, version 1.4.0* this app has been good since 2008 but the 2014 iOS 8 updates rock! the app sounds great, looks great and it worth its weight in bytes. get this app today!! p.s., i gave the app 5 stars despite it missing audiobus support; my stars are freely given, without expectation of audiobus delivery later on. i would, however, pay for audiobus support. ### 5/5 — Beautiful *2014-10-14* Thank you for your huge effort to update this greet app! ### 5/5 — thank you for the update! *2014-10-14* essential app ### 5/5 — Totally cool *2013-07-06, version 1.3* You have to have a little theory & program it, but you can make WONDERFUL SOUNDS with this thing! ### 5/5 — Fantastic! *2012-05-16* I love this simple to use drone device! Great sound! Highly recommended. ### 5/5 — Excellent if you know what it is. *2011-07-10* This is a great app for anyone serious about overtones and intonation. ### 5/5 — Fantastic drone app *2011-04-11, version 1.3* This is a great sounding and feature packed app. I am a just intonation enthusiast and i love the amazing amount of flexibility allowed in specifying intervals and timbres. Very useful and unique. My first app review-- just had to say something about this one. ### 5/5 — Deep, enlightening - and useful! *2010-04-09* I'm a singer and really just wanted a drone box for practicing but although this can do this (in its sleep) it's led me somewhere else! I also sing in a Bulgarian choir and so the subtle dissonance this can create is fascinating. You can sing over the top and it may hint at atonal or quarter-tone possibilities... Still a long way from knowing my way around but if you're into sound and exploring it, I'd recommend it. ### 5/5 — Personalized Hyptonic Drones *2009-04-21, version 0* I love this app! The interface allows you to easily layers different tones, timbres, pitches, and frequencies. If you are a fan of ambient drones, you must get this... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
