Aether Synth is an AUv3 synthesizer, sequencer and sampler for iPhone Duo, iPhone and iPad, built for creating expressive sounds that move. Start with a sound, combine two sounds into something new, introduce motion, build a pattern, capture a sample, or simply play. Aether brings synthesis, sequencing, sampling and performance together in one instrument designed to keep ideas moving. CREATE YOUR OWN SOUND Build rich synth patches for pads, basses, leads, textures, atmospheres and evolving sounds. Aether is designed to make sound creation immediate. Shape a patch directly, explore presets for inspiration, or use Random Sound to discover combinations you might not have reached manually. The result can become a finished sound or the starting point for something completely different. DUAL — TWO SOUNDS BECOME ONE Dual lets you combine two independent sounds into a new composite instrument. Choose a sound for A. Choose another for B. Blend between them and shape the result. The two sides can complement each other, contrast with each other, or create something that neither patch produces alone. Save your favorite Blends and return to them later. MAKE SOUNDS MOVE Aether is built around motion as part of the instrument. Use Motion and Random Motion to animate sound over time and create patches that evolve rather than remain static. Movement can be subtle and organic or become a major rhythmic part of the sound. This makes Aether especially suited to evolving pads, shifting textures, rhythmic sounds and patches that respond like performances rather than snapshots. SEQUENCE IDEAS Turn sounds into patterns with Aether's built-in sequencer. Create melodic and rhythmic phrases, experiment with different rates and musical feels, and develop ideas without leaving the instrument. The arpeggiator provides another immediate way to transform held notes and chords into movement, while tempo synchronization keeps rhythmic material locked to the music. SAMPLING Capture and work with audio directly inside Aether. Use sampling alongside synthesis to bring recorded material into the same creative environment as your patches, patterns and performances. A sample can become part of a larger musical idea instead of living in a separate workflow. PERFORM Aether is designed to be played. Use the keyboard and performance controls to shape sounds in real time, then connect a MIDI controller when you want a more traditional playing experience. Velocity, sustain and expressive controls allow patches to respond dynamically instead of behaving like static presets. DISCOVER INSTEAD OF SEARCHING Sometimes you know exactly what sound you want. Sometimes you don't. Random Sound and Random Motion make exploration part of the workflow. Generate a new direction, keep what works, reshape it, combine it with another sound in Dual, and continue from there. The goal is not randomness for its own sake. It is getting from a blank idea to something musically useful quickly. STANDALONE OR AUV3 Use Aether as a standalone instrument on iPhone and iPad, or load it as an AUv3 instrument inside compatible hosts and DAWs. That means the same sound-design environment can work as an instrument on its own or become part of a larger mobile production setup. BUILT FOR MUSICIANS Aether brings together: • Synthesizer sound design • Dual layered instruments and saved Blends • Motion and evolving sound • Random Sound and Random Motion • Preset exploration • Sequencing • Arpeggiation • Sampling • Performance controls • MIDI • Standalone operation • AUv3 plugin support Whether you're designing an evolving ambient texture, building a bass or lead, creating a rhythmic patch, experimenting with layered sounds, or starting a new musical idea from scratch, Aether is designed to keep the distance between inspiration and sound as short as possible. Create a sound. Make it move. Turn it into music.

EverSpace is an algorithmic reverb designed for creating enormous spaces, evolving ambience and richly modulated echoes. Built upon the CloudSeed engine by Ghost Note Audio, its architecture draws inspiration from the algorithmic studio reverbs of the 1980s, where networks of delays and diffusion were used to create spaces that extended far beyond the limits of the physical world. Rather than attempting to recreate a particular room, hall or vintage hardware unit, EverSpace embraces the more creative possibilities of algorithmic reverb. Dense diffusion, multiple delay stages and extensive modulation allow sounds to bloom into vast, constantly moving environments — from spacious reflections and drifting echoes to seemingly endless atmospheric tails. At more extreme settings, EverSpace becomes much more than a conventional reverb. Simple sounds can be transformed into thick evolving pads, shimmering textures and expansive ambient soundscapes, with subtle variations within the reverb network ensuring that the resulting space remains alive and in motion. EverSpace can be used as a traditional send or insert effect, but it is at its best when treated as a creative sound-design tool where the reverb itself becomes part of the sound. Features ○ CloudSeed algorithmic reverb engine — a sophisticated multi-stage architecture inspired by classic algorithmic studio reverbs. ○ Early reflection and diffusion network — control density, delay, modulation and feedback to shape the initial character of the space. ○ Extensive late-reverb section — create everything from diffuse ambience to enormous, slowly evolving reverb tails. ○ Deep modulation — independently shape the movement of diffusion and delay stages for lush, animated spaces. ○ Multi-tap delay stage — adds rhythmic reflections, echoes and additional complexity before the main reverb network. ○ Integrated equalisation — low and high frequency shaping plus filtering to sculpt the colour and decay of the reverb. ○ Seed controls — regenerate the internal delay and diffusion structures to produce different variations from the same settings. ○ Interpolation modes — alter the behaviour and character of the internal delay network. ○ Real-time visualisation — waveform and frequency displays provide visual feedback as sounds enter and evolve through EverSpace.

Verdict
The clearest difference is review sentiment: EverSpace at 100% against Aether Synth's 63%. EverSpace also leads on rating (5.0 vs 4.7) and iOS requirement (14 vs 17.0). Aether Synth's advantage is price ($2.99 vs $7.99) and ratings volume (10 vs 2). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Aether Synth costs $2.99 and EverSpace $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.
EverSpace holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Aether Synth has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 63% of Aether Synth's written reviews are positive against 100% of EverSpace's.
Aether Synth ships an update every 5 days, EverSpace weekly. The most recent releases landed on November 9, 2026 and November 11, 2026 respectively.
