Fun to play. My only wishlist item would be actual numbers on the tempo setting/tap tempo. ### 4/5 — Nice moods *2022-06-28* Very dreamy and soothing app. ### 4/5 — Strangely fascinating *2021-02-18* Very good for ambient play sessions ### 5/5 — Love it *2020-09-24* Very fun and intuitive. Creatively inclined individuals could do quite a bit with this app. ### 5/5 — Schön und unheimlich einfach *2020-09-22* Coolec ### 5/5 — Please create a VST *2020-06-07* This is an excellent idea and would be wonderful as a VST that can be used in my DAW. ### 4/5 — Bonne surprise *2020-04-03* Amateur et réalisateur de musique électro acoustique (orientée expérimental) j'essaye pas mal de trucs histoire de diversifier ma panoplie. Celle-ci en fait à présent parti. Simple mais le concept est ingénieux et le rendu pour des boucles originales en fade permanent est très intéressant. Je dirais : .... un peu désuet mais avec beaucoup de charme. En gratuit, ya pas a hésiter. ### 4/5 — What Svetlovska said... *2019-09-22* But already a lot of possible uses for this, and as it's for free I feel churlish for taking a star off now :( Take it as gentle encouragement! ### 5/5 — Very fun accessible deep *2019-09-16* Also the synth sounds are wonderful! Deep and well textured. I love loop process and it really makes it easy to get started and even has great easy save for songs ### 4/5 — Simple free midi/wav creator app with a *lot* of potential *2019-06-07* As a fan of Dark Ambient soundscaping, I was intrigued by this free apps ability to create evolving, decaying layers of looped sound, exportable as wav or midi files, and the inbuilt preset synth has enough variation to make the results usable in AUM Fileplayer or other more complex environments as is. However, I would gladly pony up actual cash for all or some of the following: Midi in for proper keyboard triggering (the in app ‘keyboard’ is a bit shonky) Proper real time Midi out with cc control for more interactive control of the generated sequences. Proper tempo indication and syncing to external apps. Beyond that, the opportunities to mess with the created loops whilst running (eg volume, filter, modulation), and to control rates of fade, to ‘freeze’ some loops whilst letting others fade at variable rates etc, would all be immense, and take a niche thing into true usability. Here’s hoping... ### 5/5 — Sound *2019-02-11* Campfire ambient tunes generator love it ### 5/5 — Excellent for Indian raaga composition *2019-02-02* I highly recommend for all Hindustani classical musicians to experiment with this. ### 4/5 — amibence *2018-11-12* Cool for sampling and using for ambient music ### 5/5 — A fantastic musical instrument *2018-08-26* Cycle is a great app for creating drone music. The time lag accumulation feature adds variation that you don’t generally get in drone music apps. ## Most critical reviews (10 lowest-rated) ### 1/5 — Annoying and unintuitive *2020-02-26* The default sound is.. extremely grating, and the UI goes off the side of my screen. Not sure why this app exists ### 1/5 — Sound *2018-11-15* I get no sound ### 1/5 — Na Ja *2018-08-11* Echt ein Spielzeug, mit dem man musikalisch echt nichts anfangen kann, zu nichts Gut, Sorry !! ### 1/5 — Cool idea but too limited *2018-07-10* Wish there was more control over the sound, tempo, everything! **Developer response:** Hi jlancia, I really appreciate you leaving a review; you brought up some really fantastic suggestions. I’d like to invite you to try out the latest version of Cycle, which includes controllable tempo, reverb, and 11 new sound options as well as Audiobus and IAA support. Let me know what you think! 🙂 ### 2/5 — What’s the point? *2020-07-18* I hate to be the one to say this, but it sounds like a demented cow...Awful choice of samples provided. ### 2/5 — Interface is too basic *2018-11-17* It’s an interesting idea but it does not give you enough control to do anything truly interesting. **Developer response:** Hi just.this.guy, Thanks for the review. What other features would you like to see? You mentioned you’d like more control. Control over what? I welcome your suggestions! Drop me a line: daniel@kuntz.io ### 2/5 — Good idea needs AU support *2018-08-31* Shame wish this could work with midi apps instead of generating midi which can then be transported across to other apps ### 2/5 — Not so fun *2018-08-02* Push a circle. **Developer response:** Hi, Thanks for the feedback! Sorry to hear that you didn’t like Cycle. How do you think I can improve it? Drop me a line: daniel@kuntz.io ### 3/5 — Nice, but… Ableton link ? Bpm ? *2023-06-10* It’s beautiful, it sounds nice, but the tempo doesn’t allow to set precise BPM, which is weird. Adding ableton link would change the game. As it is, it’s impossible to use with any synchronized workflow. ### 3/5 — 그저 그렇네요 *2018-08-19* 뭔가 기능이 많이 없어서 반복적인 리듬 만들 때믄 유용함 ## Most praised reviews (10 highest-rated) ### 5/5 — Endless fun *2025-05-23* Interesting fade effect looping ### 5/5 — Genial *2023-09-30* Sehr intuitiv und übersichtlich; ideal um es beispielsweise an ein modulares Synthesizer System anzuschließen und weiter zu bearbeiten 🕺🕺 ### 5/5 — Export to wav and midi + free ! *2023-09-21* omg, so good. This is fantastic and def a new source for Textures and pads. Export midi and wav supported too. banger of an app Z ### 5/5 — This is the most amazing app that has ever existed. *2022-12-11* After downloading and using this app I have now gained super powers that allow me to speak to inanimate objects. I am now taller than I was before. All thanks to this app. ### 5/5 — Excellent *2022-09-13* Interesting instrument, hope the developer adds more function in the future. ### 5/5 — Very cool - still cool in 2022! *2022-07-30* Spend some time with it. Great soundscape material! ### 5/5 — Incredible Sounds *2022-06-25* I am blown away. I definitely recommend this ### 5/5 — Blissful ! *2021-10-12* Oh man ! This app is way cooler then I had anticipated, not only is it fun but it’s also extremely peaceful, after I finished making sounds messing about…I felt kind of refreshed. Cannot recommend this app enough, keep up the great work ! ### 5/5 — Cool *2021-10-12* Great so far..... ### 5/5 — Great app! *2021-08-03* I have been having fun with this for years, but never left a rating. My apologies. There honestly is still not another app quite like it. It is a really nice blend of the generative and user controllable.
