The year is ending, and it’s time to crown the best iOS Synthesizer releases of 2025 in one article supported by the Patreon community.
Following the great interest last year in the best iOS synthesizer releases, there will be another edition in 2025. Since iPad and iPhone play a central role in my hybrid live setup, and this topic has fascinated me for over 10 years, I want to share my favorites.
This year again saw a diverse range of new synthesizers, from vintage replicas to completely original, never-before-seen concepts. Every Synthesizer desire was met on iOS this year.
Although the number is slightly lower than in previous years, many exciting additions have been made. To give you an overview, here are Synth Anatomy’s best iOS Synthesizer releases of 2025.
Best iOS Synthesizer Releases 2025
Even as the iOS market continues to grow with new music apps, comprehensive reporting on new releases remained just as difficult in 2025. This is because Apple discontinued its affiliate system in 2018, which was an essential source of revenue
Since then, it’s been a balancing act between my strong interest and a topic that doesn’t interest most people, which has led to fewer clicks. That I continue to write about iOS is thanks to the wonderful Patreon community, who make it possible. Thank you very much.
As with last year, this is a very personal list of synthesizers that I have not only tested extensively but also use live. I have compiled my 10 best iOS synthesizer releases of 2025, all with AUv3 support, for this article. The order in which the synthesizers appeared does not matter.
AudioThing SX1000
AudioThing has been very active on iOS this year, releasing apps like SX1000, June, B00ga, RES-09, and more. Even though the new Juno emulation JUNE is excellent, I opted for the SX1000 app.
First, it’s a vintage analog synth no one else has emulated yet; second, it’s a fun, simple Synthesizer with a feature-reduced setup perfect for jamming.
The AudioThing SX1000 is an authentic emulation of the beautiful, quirky Italian mono-synth, the Jen Electronics SX-1000 Synthetone, with added polyphony, effects, and more.
The SX1000 won’t blow everything out of the analog modeling synth park with its rich or extraordinary sound. However, the app has a strong vintage appeal, a quirky, unique character, and is fun to use.
AudioThing SX1000 is available now for $19,99 (on sale for $ 9,99) on the Apple App Store and runs as a standalone app and an AUv3 plugin on iOS and iPadOS.
Alexander Zolotov Low Poly Synth
There’s always a constant flow of developers coming and going. One developer who was there very early and remains at the forefront is Alexander Zolotov. Most people know the developer from his apps SunVox and VirtualANS.
This year, he expanded his series of Synthesizer apps with Low Poly Synth, which is based on the same fascinating generative concept as the previous apps Relic Waves, Relic Flow, and more.
Each of these apps has a clear focus: Low Poly Synth focuses on melodic ambient sounds. The engine can generate billions of these with little effort. Once generated, the user has a handful of parameters to adjust: volume, stereo, reverb, echo, and an attack-release envelope.
In the vast sea of iOS synthesizers, Low Poly Synth stands out and inspires with unique Lo-Fi poly sounds. And for such a low price, this app is an absolute no-brainer.
Alexander Zolotov Low Poly Synth is available now for $ 1,99 on the Apple App Store and runs as a standalone app and an AUv3 plugin on iOS and macOS.
Unfiltered Audio Battalion
When Unfiltered Audio released the Battalion drum Synthesizer/sampler for desktop in April 2024, many people wondered when the iOS version would arrive. It took more than a year, specifically until June 2025, when Battalion was finally available on iOS.
The wait was worth it. Battalion is an impressive drum Synthesizer/sampler, or better say a groovebox that lets you delve super deep into the world of drum synthesis, sound sculpting, and rhythmic generation.
Hybrid drum sculpting with drum synthesis and sample blending, experimental effects, and a powerful, evolving dual sequencer engine make this app unique in many ways.
Battalion isn’t a super cheap “instant buy” app, but it offers a range of features unmatched by any other drum synth/drum machine on iOS.
At first, you’re overwhelmed by the sheer number of possibilities for sculpting drum sounds and generating rhythms from them. But once you spend some time exploring the app and its depth, you won’t want to be without it.
Unfiltered Audio Battalion is available now for $29,99 on the Apple App Store and runs as a standalone and AUv3 plugin on iPadOS.
Igor Vasiliev NoiseSpace
Loyal readers know that I’m a massive fan of Igor Vasiliev’s apps. This year, the developer released two apps, and both made the list. Neither is a Synthesizer in the classic sense, but both use synthesis extensively.
The first is NoiseSpace, an app that I have used consistently from the beginning, whether at jams or live performances. NoiseSpace is best described as a noise laboratory or playground where it’s allowed to make noise out of anything. Crafting noise in all possible forms is the motto here.
Five fully customizable, colorful noise generators form the foundation. A granular processor processes each one. These elements can be set in motion by internal modulation, unusual sequencers, and more.
NoiseSpace is a truly experimental Synthesizer that lets you generate wonderful noise textures, noise patterns, and more. Whether used as a standalone track, embedded within a composition, or simply as background noise, these noisescapes are highly versatile.
I personally love using the app as a fade-in/fade-out background noise generator layer in my music. NoiseSpace is a 10/10. Love it.
Igor Vasiliev NoiseSpace is available now for $15,99 on the Apple App Store and runs as a standalone and AUv3 plugin on iOS/iPadOS and macOS.
Elastic Instruments Elastic OSC
Elastic OSC by Elastic Instruments is a must-have on my list of the best iOS Synthesizer releases of 2025. It was the first app in a long time that I was able to follow from its beta through to its release.
The intensive testing hasn’t diminished my enthusiasm for the app; in fact, it’s increased it. I’m still using Elastic OSC.
Elastic OSC doesn’t offer any visual fireworks. It’s a very minimalist but cleverly designed Synthesizer app that delivers impressive sound and flexibility with immediate control.
The recipe is simple: 24 algorithms from the open-source MI-Plaits macro oscillator, paired with a highly flexible automation engine, melted into a fun and accessible Synthesizer. More importantly, yes, we have seen them countless times in various hardware and software.
However, Elastic OSC, with its inspiring automation engine, has brought a breath of fresh air to this code like no other Synthesizer. It feels like getting to know the code all over again. The recent update added LFOs, making Elastic OSC even more playful.
Elastic Instruments’ Elastic OSC is available now on the App Store for $12,99 (now on sale for $9,99) and runs as a standalone app and an AUv3 plugin on iOS/iPadOS. Desktop VST and AU plugin versions are coming soon.
AudioKit Synth One J6
As a beginner, you’re overwhelmed by the sheer number of synthesizers for iOS in the App Store. Where do I begin, and what synthesizers are right for my sound? With so many new releases this year, it hasn’t exactly been any easier, or has it?
Matthew Fecher of AudioKit released Synth One J6 this year, a fantastic free Synthesizer app that is not only a great-sounding, instrument with tons of sounds but also a perfect starting point for your iOS synth exploration.
Synth One J6 is a Roland Juno-style synth for everyone. Whether you’re a complete beginner or an experienced sound virtuoso, the J6 is a versatile instrument that’s easy and immediate to tweak and offers a wide range of beautiful, inspiring sounds.
It’s hard not to include this must-have iOS app on the list of the best iOS Synthesizer releases of 2025.
AudioKit Synth One J6 is available now as a free download from the Apple App Store and runs as a standalone app and AUv3 plugin on iOS/iPadOS.
4Pockets SampleScape
4Pockets has released three high-quality apps that would fit into the list: Oscidia wavetable synth, FontStack multi-layer SoundFont player with vector mixing, and SampleScape. I opted for the last one.
I chose SampleScape over the others because of its originality. Yes, SampleScape isn’t a 100% Synthesizer, but the hybrid instrument does possess many synthesis elements.
It’s a highly creative, sequenceable multi-sampler that can bundle up to 12 instruments, each of which can be a sample or even a multi-sample.
Alongside its rich sampler feature set, including granular playback, the highlight for me is its unique sample-step sequencer. It lets you create a sequence of steps, where each step is either an individual sample or a collection of tuned samples.
This, combined with the granular playback mode, can generate super complex, evolved soundscapes. There are also plenty of filters, effects, modulation, and more, making the app an iOS sound designer’s dream.
For beginners, I would still highly recommend the legendary app Samplr. However, those who prefer something more in-depth, fully customizable, yet still easy to use, will find in SampleScape a powerful sample/synthesis playground.
4Pockets SampleScape is available now for $14,99 on the Apple App Store. It runs as a standalone app and AUv3 plugin on iOS/iPadOS and macOS (native Apple Silicon).
Cem Olcay Speaking Of Witch
Cem Olcay released his first Synthesizer apps this year: Nikaya, Testere, and Ova Synth. However, I was particularly captivated by the Speaking of Witch The Sampler app.
At its core, the app is a text-to-speech Synthesizer modeling engine that transforms text into spoken audio. Write something, choose a voice model from the many available, and voilà, you have a sound.
The results range from robotic Kraftwerkesque to highly realistic. If you don’t like the result, you can manipulate the synthesis at any time using a few straightforward tools, such as engine playback speed, pitch, and amp envelopes.
Unlike the many AI voice tools behind monthly paywalls, these sounds are instantly playable on the keyboard like a Synthesizer. Alternatively, you can export them as a traditional sample and use them in other apps.
I like to use Speaking Of With to generate voice sound sources, export to a more advanced sampler like Samplr or SampleScape, and create all-new soundscapes with them.
Cem Olcay’s app certainly isn’t the most perfect voice modeling app out there, but for me, it’s the most direct and fun to use so far, without sacrificing the musical workflow.
Speaking of Witch The Sampler by Cem Olcay is available now for $5,99 on the Apple App Store. It runs as a standalone and AUv3 plugin on iOS/iPadOS and macOS.
Aqueel Aadam Outgrowth
As the year came to a close, we received two app highlights. Besides SampleScape, Aqueel Aadam also released Outgrowth, a gorgeous app made in collaboration with musician BlankFor.ms.
Outgrowth is a synthesis-packed, sample-based instrument that creates entirely new instruments from any sample you load in. It sounds complex at first glance, but it’s incredibly easy and immediate to use.
At its core, it offers classic sample playback functions as well as sophisticated sound design features, such as original takes on granular synthesis and instant sample-to-wavetable or additive-synthesis conversion.
Original one-knob macro-style effects and flexible modulation complement these. Outgrowth is a joy to use thanks to its very streamlined, hands-on features and interface. However, it is by no means limited.
Load a sample, and the various modes will guide you almost blindly to all-new sounds. That’s what makes Outgrowth so special. An app that would rank very high if I were to make a 2025 release ranking.
Aqueel Aadam Outgrowth is available now for $19,99 on the Apple App Store. It runs as a standalone and AUv3 plugin on iOS/iPadOS. A desktop version is also available as a separate purchase.
Igor Vasiliev ExoSphere
Readers of the entire article know that I said Igor Vasiliev released two new apps this year, and both made the list of the best iOS Synthesizer releases of 2025. The second one is called Exosphere, an app that joins the many sample-based generators this year.
Like SampleScape or Outgrowth, it’s not just a synth or a sampler; it’s an exciting mix of both, paired with the experimental DNA of Igor Vasiliev’s apps.
ExoSphere is a multi-layer, sample-based instrument capable of creating endless ambient soundscapes/textures that constantly evolve. The heart of it is the granular synthesis engine that creates dense textures by fragmenting the loaded samples.
Five layers, each with freely adjustable parameters, give the user a great deal of sonic freedom. Thanks to the built-in drifting modulation, the textures never sound monotonous.
Like any Igor Vasiliev app, the workflow takes some getting used to. But once you get the hang of it, it’s incredibly fun and transforms the iPad into an amazing soundscape machine for on-the-go use.
Igor Vasiliev ExoSphere is available now for $14,99 on the Apple App Store. It runs as a standalone and AUv3 plugin on iOS/iPadOS and macOS.
