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!"

"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.

Pure Oneness

As a music maker and sound Healer this is the only app I have found and I’ve spent hours and hours trawling to find something that has the precision and variety using intervals that is so important. I use this in my compositions and in my mantra classes I teach. It’s so good it almost makes me not want to tell anyone about it lol. Bless you for creating this simple but brilliant application. I look forward to seeing and hoping you’ll continue to take this concept further. I hope with the rubbish that’s out there nobody dares give this a bad review, and completely worth the money.

Elliot lazy the morning ,

For money amazing. Great chorus!!

The good stuff first. It’s instant, you can see what key you’re in, which you can change. Just add volume to each note or tone and you’re off. There are a selection of timbres or osc to choose from and up to 8 notes simultaneously and I can add a beautiful chorus effect. There is an option to oscillate between 16 notes by replacing the chorus option which allows another sound bank of 8)
Fine tuning for me is where the magic happens. the vibration or pulse of each note against one another lifts up the overall experience.
The lack of being able to change individual osc shapes is short sited, this could be a good in app purchase. ?
At present I can only change osc types in banks of 8 at time which leaves out a bunch of individual tweaking, Droneo 2 perhaps? The main alteration To sound is made via screen 2 by moving blobs round a spiral . The larger ones are higher up in the mix.
I’ve yet to discover what speed and depth notes blend into one another but they do on some presets all by themselves it seems.
Anyway it’s lovely, peaceful, serene, moody and time consuming. Have fun.
I hope this developer comes out with more stuff

Hi Elliott!
The "consort" timbres and the "Custom" timbre all can assign a "real" timbre to each "reed" - Custom allows for LOTS of tweaking. Check out the collection of web based voices (triple tap on a voice name or long press on it). Or you can also get them by going to
Droneo is pretty ancient (2009), but I'm working on a new app with fresh take on a lot of the ideas.
You - and others reading this - can always drop me a line at with questions about Droneo and my other apps!

Lovely app

Lovely app, doubly so since it's been updated: apologies to the developer for not updating my previous review complaining it was out of date.
Produces fantastic slowly shifting sonic textures.

Developer Response ,

It was updated, and with 1.5.5, it's working with AB3 and IAA. So you should be able to update nicely!
