Apple likes to change its infrastructure a lot, so if you like running my apps on older devices, you may have to save the version you have now in case I update it to a version that cannot run on an old device. Here is a little tutorial on how to do that.
  1. You can hear a few demos and examples of various musical apps on SoundCloud
  2. Here's an interview, by Warren Burt, mostly about AUMI and Polyharp, published in SoundBytes Magazine, September 2020 edition
    Music for Tablets — Interview with Henry Lowengard, App Developer
  3. Here's a nice interview with me by Mark Hurst on WFMU's "Techtonic". There are lots of links in the playlist! (WFMU archives)
    Radio Interview by Mark Hurst, "Techtonic" April 9, 2018, WFMU-FM.
  4. Here's a lecture I gave at the Hudson Valley Tech Meetup in July, 2017. It automatically skips ahead 15 minutes to ge to my part. (Facebook video)
    HV Tech Meetup
  5. Listen to me talk about some of my apps on this old radio show with host Peter Wetzler on WGXC. (February 2011, but still pretty good).
links and performances
Here are links, performances, recordings, and videos by people using my apps! Thanks, folks, keep the music coming!
Here are App Reviews and Responses to them!

great app...a must have *****
by oneillrb - Version - 1.4.0 - Apr 21, 2015
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.


Utterly Brilliant
by Jogging jim April 24, 2019
This app is a real gem. Simple to use but producing ver[y] sophisticated results. I use it to act as a fool[tool] to improvise against with sing and guitar. Highly recommended!

Pure Oneness
by soulwizardary May 12,2018
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.

Beautiful inventive drones
by Keywiz - Jul 24, 2016
Meditation, creation, inspiration all within this wondrous app. Best Droner Gets much needed update!

King of the drones!
by Nkersov - Jul 22, 2016
Nice work, Henry. Out of the blue an update that restores AudioBus and IAA functionality, plus iPad interface. For drone sounds, this is brilliant.

Droneo is the drone master tool/instrument!
by miulew - Aug 1, 2016
Searching for freely adjustable drones of all kinds? The search might be over... Not only equal tempered drones but also just intuned and Partch intuned and more and more. The possibilities are endless. As well as for personal drone usage it is a powerful tool for education of music theory and sound cognitions, put into practical hands-on. Also great for "just" listening and meditations. I am highly recommending Droneo for all who seeks drone solutions!

Useful but complicated ***
by lilbix - Version - 1.3.51 - Mar 4, 2015

I find Droneo useful for practicing trumpet. The steady drone gives me a reference for intonation and allows me to improvise freely. Unfortunately the interface is extremely complicated and lacks the most useful feature: an on-off toggle. I hope the developer will include this feature at some point.

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. Anyone musicians lucky enough to discover Droneo will find it as cool as I do. Could be used on a daily by those practising relaxation techniques & is a steal at the price.

Bout time!!!!!
by Hashiki - Version 1.3.44 - Dec 30, 2012
Henry's apps are all top notch essentials and ive been waiting for this one my whole life even though i had no idea it ever would exist!
by Calroy
Super well designed app, beautiful UI, delicious drones. The tone spiral is brilliant. Using this app for intonation practice as well as live performing.

[synthicity itself]

Seriously UnderRated !!!!

I could not give this cat enough stars ... THE LEVEL OF IGNORANCE OF THE MAJORITY OF pEOpLE/consumerS IN THIS BARELY SOVEREIGN COUNTRY IS APPALLINGLY MORE OBVIOUS TO ME THAN EVER;SHAMEFULLY SO LOW A LEVEL SEEMS TO ASSUMED BY ALL ...NOT THIS GUY THOUGH I LOVE HIM .The only developer who's app I get after just reading their name!!! BEWARE HE THINKS & if you use his stuff yoU might T?

and here's another one:
Synthicity is like no other!

by Sparkly Hippo on June 4, 2012

A very musically advanced and fun instrument! The new tones are great and very usable, whether in recording or instantly expressive play. Lowengard apps are some of the coolest in the store. Dig?


So much better than what you think it is.

by Wet Food June 27, 2020
Simply brilliant and deep
