Other than that, it’s good. ### 4/5 — Good app *2021-02-27, version 3.31* It’s good but one thing it helps quite a lot ads so maybe if you fix that will be a five star app ### 4/5 — Great fun! *2013-06-18* I enjoy using this app, especially for the magnetometer. However, for me, the y and z values do not affect the pitch that sounds. Only the X value affects pitch, an for some reason, when the X value of the magnetometer is negative, the pitch defaults to its minimum pitch, no matter what. It's lots of fun! ### 4/5 — Not sure it's a theremin... *2013-03-29, version 1.2.2* ...but it's a cool little app which ties the iPad's sensors to a signal generator and makes sounds from movement. If anybody learns to play it like an instrument I'll be very impressed. ### 4/5 — Fantastic *2013-01-24, version 1.2.2* I love this app very annoying sounds! :) ### 5/5 — Nice *2012-12-08, version 0.2* The best free theremin app i found. ## Most critical reviews (10 lowest-rated) ### 1/5 — Camera Sensor Issues *2019-05-24, version 3.31* After the purchase of the Camera Sensor from the store and pressing the “Toggle” button, the app always crashes rendering the user to deem the purchase useless. Hoping you would resolve this matter or return the payment. Thank you very much! ### 1/5 — Doesn't work for me *2017-04-17, version 3.31* Nice visuals but unfortunately no sound, despite a lot of fiddling. ### 1/5 — Need more instructions *2016-10-25, version 3.31* I can't figure out how to use this. I need some ghostly sounds, like the ones that come from a theremin - but this only makes screechy computer sounds that are actually painful. ### 1/5 — Really disappointed *2016-03-06, version 3.31* I could barely make sense of what the various sensor settings were trying to do, and I wanted them to take over various aspects (eg pitch, volume) of the sound generation, not make an additional one. ### 1/5 — Doesn't work *2014-06-25, version 2.0* IPhone 5s running 7.1.1 not a single sound. Broken app. ### 1/5 — No sound *2014-01-18, version 1.2.2* On my new iPhone 5s I was unable to make a single sound. Nothing. Deleted after 5 minutes of frustration. ### 1/5 — No sound also on iPhone 4s iOS 7 *2013-12-20, version 1.2.2* No sound ### 1/5 — No sound iPhone 4S ios 7.0.3 *2013-11-27, version 1.2.2* No audio iPhone 4S ios 7.0.3 ### 2/5 — Sounds absolutely nothing like a theremin *2017-04-11, version 3.31* It works, crash free, but has as much in common with its namesake as a car alarm. ### 2/5 — Ehh it's ok I guess *2012-11-10, version 0.2* You can't stop the sound without going into the settings and its really loud in my headphones ## Most praised reviews (10 highest-rated) ### 5/5 — Great! *2018-09-01, version 3.31* Great app to play around it, plus my 3 year old and 1 year old found it very easy and very fun to use. ### 5/5 — Fantastic. *2015-03-10, version 3.31* This app is simply great and i can't wait to let my 20 month old son get his hands on it as well. ### 5/5 — Cool *2015-01-19, version 3.31* Really like this little app. It's a fun noisemaker and all the customizable options are pretty cool. ### 5/5 — Works Great ! *2014-07-17, version 2.0* ...so easy, a caveman could do it! ### 5/5 — Amazing *2014-04-18, version 2.0* With infrasound and everything in between, Theremin introduces many options for irritating roommates, family members, dogs, or strangers. The user interface is wonderful; I only suggest adding the option to enter a specific number in the min/max frequency selector. (Some devices are incapable of producing infrasound, by the way.) ### 5/5 — Scares my cat! *2013-09-10, version 1.2.2* It would probably scare my dog too it I had one. It would probably scare my girlfriend also if I had one. ### 5/5 — Very Cool! *2013-08-08, version 1.2.2* Thanks for letting me use both my left and right brain to make some really freaky sounds!! ### 5/5 — Auto tune *2013-01-18, version 1.2.2* I like the autotune feature ### 5/5 — Simple & easy *2013-01-16* Nice no-nonsense execution! ### 5/5 — Fun *2013-01-15, version 0.2* Could use more audio channels. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
