## What is Droneo?

Droneo will bathe your ears with rich polyphonic textures!

Droneo is a synthesizer which drones with various timbres and precise intonations that blur the distinction between tones, timbres and chords. Its drone is great for meditation, centering, and calming,  walking and biking, but also can be set up for discordant noise and insect-like buzzing and chirping. 

With Droneo, you can create surprisingly rich, motion filled drones which change over time in a controlled way.
Quietly nested in your earbuds or blasted though your stack of amps, Droneo fills your droning needs! 

Droneo is a relative of one of my other iPhone Apps, SrutiBox.

Droneo works with Audiobus and IAA to expand its droning capabilities.

Best app I have!
"Absolutely love this beautiful app that I use every day. Fantastic concept. Ingeniously implemented. Worth buying an iPhone for!!"
 -- Petey Pete UK

''Brilliant !  Haunting & beautiful.  Inspiring to use in creative music projects for recording or even live performance.  The aching, melancholy voice drones are a perfect, gentle way to relax, meditate, induce calm & even aid sleep.  Henry you have put something wonderful into the world here, not only an engrossing fun app.  Any musicians lucky enough to discover Droneo will find it as cool as I do.  Could be used on a daily basis by those practicing relaxation techniques & is a steal at the price!"
--   JC / ENGLAND'

"Composers delight" 
This is a truly beautiful little app, and should not be missed by any musicians or dabblers into minimalist or drone based composition. It produces a wide variety of mesmerising drone based tones, all customisable by the user. I have been exporting the audio straight into Logic via a midi keyboard and the results are fantastic. The creative possibilities presented by the iPhone continue to astound me! I highly recommend this app.
   -- Australian App Store comment

Droneo is great whether you use it recreationally to relax or meditate, as a utility either to help tune, educationally to better understand harmonic interaction, or creatively with other music equipment. With a little creativity and effects :) you can use it with almost any type of music. For me, it's had a lasting appeal way beyond most other apps in this price range.[...]  Recommended.

The most forward thinking music app I have seen.

This app allows me to deal with ratios in sound. Most other music apps are limited to equal temperament. Thank you Mr. Lowengard for taking a step forward in musical thinking, and giving us the chance to experience music in a new way via your app, Droneo!

Wonderful software. With the evolving voices it's as though I'm being accompanied by a living breathing entity - at the same time combined with precise control over what's played: the tuning, the notes and harmonics.
 -- materialworlds


 The settings for all the intervals can be visualized and manipulated using a special "Tone Spiral" interface.

Droneo is also an excellent way to play with the way chords fuse into timbres. 
You can get a feel for how certain timbres fit "naturally" in certain frequency ranges, and  how tunings and timbres and chords intertwine.

### 5/5 — Fantastic Just Intonation Ear-Training and Improvisation Tool

*2026-07-16*

For me, Droneo is fantastic for ear-training in just intonation. I also enjoy improvising vocally with the drones. 

Thank you for this 
beautiful and useful 
pedagogical and creative tool.  

Please make a version for the iPad or Mac that can alternate more chords and use more consecutive partials/pitches. I would like to expand my improvisation with this tool and create possible foundations for compositions. I would gladly pay $25 or more for such an extended app.

Blessings to you and yours in Jesus Christ,
Mark Lybarger-Monson, Ph.D. in Music Composition from University of California at Santa Barbara (UCSB)

### 1/5 — Distorted sound and no refund option

*2025-04-04*

Sound output quality is terrible with major distortions. When I tried getting a refund a few seconds after trying this and the option is not available.

### 4/5 — Cannot figure out how to access or export recordings

*2024-01-18*

I tried using the audiocopy app but nothing pastes/exports  there from Droneo

### 5/5 — Found This Gem By Accident

*2023-09-28, version 1.5.6*

I found this app through a comment on a YouTube video discussing a eurorack module that makes drones. This is a cheaper option and it is easily accessible for my setup. I plug my iPad or iPhone into my patchbay with my hardware synths and effects and it works perfectly.

I’m also autistic and have a few other mental disabilities and this app allows me to quickly listen to calming drones when I am overstimulated or anxious. 

Thank you for creating this. My only suggestion (and maybe this is because I am still learning the app) would be to implement a way to modulate the tones on the spiral interface automatically. I know there is a chorus and other modulation methods, but maybe some more would be absolutely incredible. Again, I love this app and will probably buy more from the developer.

### 5/5 — Incredible work

*2022-08-02*

This app has been instrumental for me as it does things that I have found no other can , the ability to dial in frequencies no matter how detailed or obscure and create Pythagorean intervals using them. As a sound healer and musician this is gold. I own many apps many synths and none can do this. So …. Please please tell me your working on the follow up to this ? An auv3 capable new version of this wonderful creation. 

I would gladly part with good money for your next version of this. New interface and some added features while keeping all you’ve achieved with this. Many thanks from the Mind Orchestra.

**Developer response:** Thanks! I've been trying to put together a worthy, less confusing successor to Droneo for many years. It may happen! I use it myself a whole lot. I hope you take advantage of the years and years of sound experiments I've put in the Droneo Voices Repository. If you come up with a good one, you can upload it by exporting it and pasting it with the link on this page, and I may add it to the app's presets. https://jhhl.net/iPhone/Droneo/Voices/

### 5/5 — Excellent, unique and deep

*2022-03-05*

I have had Droneo for a number of years and still feel it is revealing it’s depth. Creates an astonishing range of sounds. Respect to Lowengard for such a great app.

### 5/5 — Amazing app

*2020-12-19*

Even if you don’t know anything about music and you just want to meditate this is a must app. And if you want to make music this one of the first apps you have to get. Killer app. Please Auv3, I’ll buy it again if you make it Auv3

### 5/5 — Awesomest app ever... but iOS 14 broke it!

*2020-09-28*

A tragedy! I hope this is fixed soon...

Edit: Thanks, developer! Works now. Yay, this the best drone synth for the platform by far.

**Developer response:** Hi GravyTop! It's working for me on my iOS 14 iPad & iPhone - maybe delete it and try again?

### 3/5 — Droneo

*2019-11-21*

Enjoying this app and have used it once or twice within Inter App Audio in AUM, as well as standalone. However it loses stars (plural) for refusing to close and being a battery drain; it remains a drain on battery even after swiping to dismiss it. Only a full restart of the phone or iPad actually stops it.

### 5/5 — Fantastic app.

*2019-05-27*

It just does one thing but it does it beautifully. Props also due for the formidable manual as well. All apps should have a manual as good as this one.
