Wotja: Generative Music | Creator, Lab, Mixer & Player

Wotja User Reviews

"Best app for generative music, nothing compares."

"Wotja is unequalled for generative music software. The way the tracks interacts in a way which makes musical sense isn’t found anywhere else. They are the expert in the field, learning from their past, from Koan, Mixtikl, Noatikl... To really get the most out, you have to spend the time learning it, neverless just putting a random “jam” on can sometime sound better than anything else."

"Best Thing Since Eno Picked Up A Casio"

"Sliced bread everywhere, can't talk too busy, things to do."

"Simply the best ambient app ever made!"

"It looks complicated, there is a little learning curve and it does take a little time to learn. Once you know your way around it is very easy to create ambient masterpieces, from single tracks to entire albums. This app produces endless amounts of totally unique ambient music. Amazing!"

"Essential music app"

"This app is vital to my workflow and music creation. Whether I am using it’s generative midi capabilities or micro editing the onboard synths, Wotja has made making music with iOS so enjoyable and productive. I don’t know how I ever made music without it!"

"Koan Lives"

"The first computer program I ever bought was SSEYO Koan because I adored ENO and what the genius Cole Brothers had invented. Now some 25 years later Intermorphic delivers yet another esoteric magic music tool. So glad I found the dark theme and I’ve spent hours and hours in generative music bliss of Wotja since I bought the app"

"Once again a great artistic application"

"I had already purchased the version for the Mac and now I have purchased the version for my new iPhone, the audio rendering is superb and the compatibility with the tracks created with my mac is complete. The developer is a very kind person and always ready for requests for help or clarification, which should not be underestimated in the boundless panorama of applications that sometimes are not even updated. 10 and praise for this software!"

"Fascinating App..."

"Endless possibilities and terrific support!"

"Combination of power and useability"

"It's an incredibly satisfying piece of software to use. I enjoy the pieces I create, and expect to get better at it as I gain familiarity with what the package can do for me. An(d) the price is way cheap, for the use I'm getting out of it."

"Hugely Powerful"

"This is an astonishingly powerful bit of kit... The range of options and control you have over your sounds is immense... Make no mistake; this app is wonderful."

"Brilliant musical playground for creating, inventing and relaxing"

"One of my best app purchases this last 12 months and I’ve bought quite a few."

"A drone and ambient enthusiast loveletter"

"I just love letting it run endlessly savoring the ambient and different arrangements, experiment with it and I feel I even didn't scratched the surface."

"A gem"

"Love this app for relaxing."

"Power to make it your own. "

"We all want to make it our own. This is it. Not that it is easy but it is worth it. Why build on others work and be told later you don't own this. There is great potential in this software"

"Must have for generative music"

"Very deep app for generative music - the best I think. Very good support from it’s developers. Strongly recommended."

"Try it ... your mind will expand!"

"The devs are very responsive and very nice. There is nothing like this out there... and believe me I’ve looked. "

"Refreshing!!!! "

"First of all, the developer(s) are amazingly responsive, helpful, patient, kind, and enthusiastic. Communication is a pleasure. It's an otherworldly environment that helps inspired creativity."

"Wotja is excellent!"

"Best generative music product I own!"

"Very good software"

"I bought this software to create ambient background music for relaxation and meditation. This software is just perfect for my needs and easy to use. Also the export features are great. Thank you guys for this amazing music creation tool."

"Helps you approach creative creation with different work flows "

"This app is fantastic you can quickly begin to generate something inspirational and add hone to find something by exploring. The depths of the app are there to discover and explore at your own speed and need but is not a bar to making and creating with little or no musical or synthesis knowledge. The multiple creative workflows mean that you have many ways to generate projects and don’t fall into one groove. Wonderful and inspiring the app is a piece of art unto itself."

"Instant gratification, infinite possibilities, endless wonders "

"The king of generative apps ... and capable of pretty much anything from classic Enoesque plinking to cavernous Steve Roach dronescapes. Complete non-musicians can produce works of compelling brilliance by just following their ear and taste, while seasoned musoes can turn a vague intuition in their head into endlessly unfolding sonic magic."

Magazine Reviews


"Wotja is really one of a kind in the generative music space, there’s nothing like it at all. It’s really a seriously big bundle of tools, but all in one app, and all with the same purpose. Intermorphic has some serious credentials in this area, having been in the world of generative music for well over a decade now."

User Reviews


"Wotja can be as simple as a visual and auditory experience that mixes written words and generative music... Wotja can also be a very deep modular environment where you can edit every aspect of your music and sound parameters... I don't think I'll ever get to explore all of Wotja's features, but I do learn new things every day with the help of Intermorphic. Anytime I hit a wall, it gets knocked down pretty quick with explanations for those little things that aren’t readily apparent to me."

"Wonderful app"

"I have been purchasing Wotjas with every update for years. It’s the only app I have done that with, ever. I love how I can choose to go as deep as I want into crafting soundscapes while at the same time have the option to just "one click" load beautiful pre-made yet randomized songs."

"mad value for an unlimited creative powerhouse"

"A stunning start-of-year launch price for the single-purchase version of this titan of an app."


"An excellent music-making tool of almost unlimited depth, with strong and sympathetic support."

"Serves Well"

"Great piece of work!!! Thank You."


"As an accomplished musician in my own right, investigating alternative means of generating sound is a longstanding interest of mine. Even after a thirty year career in the arts, this app has completely changed my perception of the concept of music itself! I implore all students of music to explore this software in its entirety- this past week has had me rediscover my love for creation."

"The Most Advanced Generative Music and Sequencing Solution, Period"

" ... Wotja benefits from the long pedigree of related generative music apps, as it comes bundled with plenty of their content. There are lots of little apps that will bring some measure of generative/aleatoric aspects to your music, but none can offer the depth that Wotja delivers. I’ve used it to sequence hardware and iOS synths without issue."

"Great app, complex, deep and unique"

"I'm an engineer, I like tinkering, I like creating stuff, I like music sound and synthesis, I like puzzles ... I love Wotja. Such a cool app, very flexible and deep. It really can be quite addictive, challenging, complex and fun. Ticks all the above."

"Simply the best"

"Probably the best generative music app on iOS. I’d wholeheartedly recommend this to anyone with an interest in music making."

"Superb package for ambient music creation"

"Wotja a complete package for the creation of ambient, generative music. Offering complete and comprehensive control of all parameters, it makes possible gorgeous, ambient music. As someone who has been creating this kind of music for a while, Wotja enables me to achieve my vision in ways no other software can. The monthly subscription model is a total steal; if you need support, it’s fast, technically sophisticated, and patient. The latter is important as I think I have asked every dumb question I can about the software. The support people are unfailingly friendly and very helpful. If you have the ambient gene, this package is for you."

"Exceptional Dimensionality"

"I have been in love with Intermorphic products since the days of KOAN Pro. Wotja 19 adds a whole new dimension to creativity and playback for professional musicians and rank amateurs like myself. This program is awesome!"

"An excellent app!"

"I've used Intermorphics products since Liptikl and Noatikl 2. They've been an indespesible part of my creative flow for a long time. I held off from switching from my trusted Noatikl 3 app for a while, but finally made the switch to Wotja Pro 19 and I couldn't be happier! I've been moving all my old Noatikl files over and am re-programming my scripts for Lua to Javascript. I'm really happy with the improvements since Noatikl!"

"perfect for what it aims for!"

"... this is a dream. I am freaking out at how scary or lovely you can get."

"Amazingly powerful!"

"Sounds great on its own. MIDI & audio export. Top notch support by developers. Hours / days / years of fun!"

"Worth spending the time learning it"

"It’s deep... takes some real effort to go deep, but then you realize the real power of it, from patterns, scripts and all... you can produce some happening stuff with it :-)"

"Love this app!"

"I have been a Wotja user for several years and it’s always a pleasure to to re-purchase whenever they create a major upgrade. There’s SO much in this app. You can really geek out on the smallest of setting and yet it’s also pretty easy for new and not-so-musically-skilled person to get going with."

"The Best"

"I'm really fond of this app. I use it in both simple and advanced ways. The sound quality is excellent. The sounds have a beautiful crystalline, digital quality that is clean, refined, and unique, better what most music apps can do. The obvious strength is endless ambient listening, but there are deep parameters and with a touch of creativity and inspiration one can use the platform as a jumping-off point for fascinating generative composition, especially if you have a mind to export midi into DAW projects. Thanks very much to the developers. A magical app! I hope they keep refining and updating it as they have now for such a long time. Unfortunately this app is one of a kind, and I say unfortunately because when it comes to generative platforms it's one - and probably the best - of only a few options that I’m aware of."

"Wotja think of it now?"

"AirPods and Wotja Flow. Heaven."

"Amazing Stuff!"

"I love the textures I’m getting already. If you’re thinking of purchasing, it’s well worth the price!"

"Fantastic support"

"Wotja is a fantastic generative sound canvas that you can control - or just listen to. It can be as easy as loading one of many included mix albums, to the generation of random mixes, to manual mix editing to actually getting dirty under the hood with the voice editing and the instrument design. It goes pretty deep!"

"Works well"

"This company is fantastic at what it does."

"A vehicle, a journey, a playground"

"All the toys, and far more than the sum of its parts. (Autocorrect had it as "more than the sum of its arts", which is actually more accurate)"

"Generative Music Masterpiece"

"These guys are Ambient legends and now we can all work with their tools. Create your own ambient tracks or use Wotja to create some initial ideas to build upon. I use this to quickly bang out some background music, but mostly it is the starting point for composing. I find having Wotja build a nice little background bed I can compose over; my tracks go places they never used to (in a good way). Wotja can be used as a stand-alone app or as just one element in your songwriting toolkit. I really love Wotja. A lot!! ... When you think of the fact that these guys helped develop ambient music generative technology from its infancy, then supporting them by buying the app only makes sense."

"Fantastic App!!!"

"Get the free version, try out everything for 3 days or just buy the current yearly version. You will not regret it!"

"great compositional tool"

"an indispensable instrument for widening your scope, when it comes to composition. Thank you for your work!"

"Surprisingly good results"

"This app is so much fun and the results are often beautiful and interesting. The cut-up technique lyric generator is worth the price. It's flexible enough so that you can steer the direction of the outcomes and continue to refine until you find something you like. I don't think there's another program like this."


"Loving this application! A great way to explore some amazing sounds and create new music. For all of it’s depth it’s incredibly easy to get started. Tech support is phenomenal. These guys really care about what they build! Highly recommended!"


"... a specialist app for making generative music ... the developer goes to great length to make it as accessible as possible to all (without losing the appeal for more experienced users). I really like it ... Recommended."

"Deep and professional app"

"If you loved Noatikl and Mixtikl then checking out Wotja is almost required. The guys at Intermorphic Ltd have wrapped up all the great stuff from the earlier apps and delivered them here in a beautiful package. I consider it my number one composing tool when I'm working in the Ambient genre."


"Intermorphic continues to produce brilliant apps. The possibilities of Wotja are vast and deep."

"Unique App"

"A unique app, which is getting lots of updates. Very deep, it requires considerable time to delve into it's complexities. It's well worth it though, in my view."

"Best generative music app"

"There is so many possibilities on this app. The creators are super nice people, theres only 2 of them but they do answer very quickly and are not greedy... It really scares me to think that the developers would stop supporting and growing such amazing tools, please don't! Much love"

"Completely changed my mind"

"I recently purchased the "pro" (non-subscription based) version of this. Like any musical instrument, it rewards more practice and play. And the fact that there are so many parameters to tweak, change (or not - you can use templates and leave them alone, but where's the fun in that?), modify, etc, only makes for more surprises and creative experimenting. You can just experiment, as with modular, old-school analog hardware, and see what happens. And quite often, there are very satisfying results. This is very powerful software. These guys are ***THE*** pioneers along with Eno in generative music. They clearly love it and deserve to make a decent living and be supported for their long-term and continuing work. Highly recommended."

"The perfect sleep machine."

"Intermorphic is awesome!! I was a little hesitant to purchase another subscription service, but it all really factors out to only about a dollar per month. Wotja is hands down the best generative software that I have ever used. Extremely musical. Keep up the good work."

"Still the best MIDI composition tool in my toolkit"

"Keep in mind that even though the app is associated with "generative music" and ambient sounds, it is possible to create music in any genre with this - its possible to direct every voice to play note by note OR just tell a voice to improvise OR tell a voice to follow and/or harmonize with other voices. ... nothing gives this much control to a composer on iOS and I've tried almost every sequencer, generator, MIDI tool available. It's very much worth learning, the developers are responsive and there is a great website for support."

"Light years ahead!"

"by far the most sophisticated and powerful generative music application available."

"Every kind of amazing"

"Intermorphic's apps have always been strong on interoperability, but here they've managed to combine what is effectively Noatikl 4, Mixtikl 8, and Tiklbox 2 into a single beautifully-designed all-in-one generative mega-app – putting an end to all the copy-and-paste faffing that used to be involved if you wanted (e.g.) to use Noatikl content in Wotja. ... this is the culmination of everything Intermorphic have done, and an all-in-one machine for the creation of wonders."

"having the time of my life"

"It was amazingly easy to connect to my PC DAW with rtpMIDI so I can use my own sounds but it's hardly necessary, the latest Sound Engine is excellent. I thought I'd just say...excellent job. Thanks."

"Professional grade!"

"Wotja ... is the most powerful and feature rich application for generative music creation."

  • The Wotja iOS versions also includes a TV app and an Apple Watch app.
  • The free apps are updated on a rolling basis meaning they can always get the most recent (OS supporting) update.
  • Pro Feature Set alternative: Get Wotja Pro 20, the paid-for version (see below).

Wotja Pro 21 will be the paid-for version of Wotja 21 in 2021. It will follow the same principles as set out below.

  • Feature Set: The Wotja Pro 20 apps are the Paid-for versions of Wotja Pro and they all have the Pro Feature Set; the iOS version also includes a TV app and an Apple Watch app.
  • Updates: The Wotja Pro 20 apps will get all relevant Wotja V20 updates only during the course of 2020. To be clear, that means there will be no updates for it in 2021 or later. See the FAQ on our Upgrade/Fullgrade model.
    • Tip: Get Wotja Pro 21 if you want further updates in 2021, or Wotja Pro 22 for updates in 2022 etc.
  • Pricing: For all app stores other than Google Play our pricing for all paid-apps is in USD and is a sales tax inclusive price. Google Play does things differently and we have to set a net rice in GBP to which sales taxes are then added. That means the Google Play USD price shown above is just an approximation (hopefully not too far off!).
  • Alternatives (iOS/macOS): Get the Subscription version and take out a Pro Feature Set Subscription (see above).
