A no-nonsense Binaural Beat and Isochronic Tones Builder.

Do you ever have trouble concentrating or relaxing. Use this app to create a binaural beat or Isochronic tones session to tune your brain to the mood you desire.

The theory behind binaural beats is that if you apply slightly different frequency sine waves to each ear, a beating affect is created in the brain itself, due to the brain's internal wiring. If, in the presence of these tones, you relax and let your mind go, your mind will naturally synchronize with the beat frequency. In this way it is possible to tune the frequency of your brain waves to particular frequencies that you have selected, using of the four bands: Delta: deep sleep, Theta: dreaming and intuitive stuff, Alpha: awake, focussed inside, and Beta: awake, focussed outside.

It is also possible to produce mixtures of brain waves of different frequencies by mixing binaural tones, and in this way, with practice and experimentation, it is reportedly possible to achieve rather unusual states, such as out-of-body stuff, and more. See the books by Ken Eagle Feather, and the Monroe Institute site for more details. The Monroe Institute have apparently put 40 years of research into these techniques.

This program enables you to create your own Binaural Beat sequences by layering multiple voices and background sounds on top of each other. Each session consists of one or more voices and backgrounds. Each voice can have a different start and end carrier frequency, beat frequency and volume. This means you can 'slide' up or downto a certain MindState. Each voice and background can have starting time greater than zero. This enables you to layer different tracks onto each other (see caffeine for example).

This brainwave entrainment app Comes with 20 pre-programmed sessions. But you can create as many sessions as you like.

- realtime audio synthesis, no pre-recorded sessions
- create and store as many sessions as you like
- layer as many voices as you like (as many as your hardware can handle)
- layer as many backgrounds as you like
- set different start- and stop values on a voice for volume, carrier- and beat-frequency
- session keeps playing when screen locks or using other apps
- session mixes with sound of other apps like iTunes
- export and import your Sessions with iTunes Sharing
- export and import your Sessions by email
- crashing waves background option

MindState is not Hemi-Sync ®

Hemi-Sync (short for Hemispheric Synchronization) is a trademarked brand name for a patented process used to create audio patterns containing binaural beats, which are commercialised in the form of audio CDs often accompanied by a guiding voice.

I am disappointed that the techniques used in Hemi-Sync are not accessible to everybody. It is heavily protected and patented.

With MindState you can freely experiment with Binaural Beats. Please share your experience and knowledge with the rest of us.

Look no further. Quintessential binaural beats app

This is the most clean, least buggy, most simple yet customizable binaural beats app on the App Store. Customer service response was very quick too. It is well worth the modest price; I have different Apple accounts for work and personal use, and I gladly bought this app for both Apple accounts to be able to use it at work from my WiFi-only personal iPad (which I work while listening from) and remotely via my work mobile phone. I suppose I could have bought it for just my work mobile phone, but I want to support this app developer to thank them for their time and attention making the perfect binaural beats app. Most other of these types of apps are silly, with added ambient noise, woo-woo music, and very little options—and all of those are overpriced to a laughable degree. This app rules them all.


AUDIOBU$ Worthy !!!!

#2 Attention Discchord Believers-WAKE-UP!!!
& 3 look up the Discoveries ov thee "MONROE INSTITUTE "
Discchord called this a "fart" app ? This is a site to champion a fringe music making process in order to gain its acceptance right ? And teach too ;correct -!
Someone needs to monitor this depraved souls meds' a little closer or at least show him that FACTs' about holding his blood stained devices to children's heads' and what really "F's up brainwaves' " (his words' not mine Apple won't publish how I feel these are facts!!!) and the fact that this is a "Health& ....." & produces Tones in Hertz Doesn't tell you people anything ?
Humans' Are ELECTROMAGNETIC BEING FIRST then chemi-kill!!!!
I actually believed that "discchord"was not Voicing any Political or Religious Views to stay focused on "theMusic" ??yet this fool is Card Carriering WorshipfulMaster ov theCriminalCorporateState !!!!Where Ignorance is Strength !!!!!
If I were this developer I'd sue that depraved degenerate for Hoping to be a Fart but really turned out to be a "MESS" instead !!!!!

Help with carrier vs beat frequency adjustments

For some reason I am unable to connect to your support page. I am wondering if you have published a document that shows how to properly set the carrier/beat frequencies when adding a tone. It would help to know a range that describes expected results, so a cheat sheet would be helpful.
