Polychord turns your iPad into a chord instrument — a full band at your fingertips. Nine chord circles hold every chord in your key — arranged so the right one is always under your fingers. Tap a circle to hear it, and the ring around it offers the colors: sevenths, sixths, suspensions. Strum across the keys like a harp. You can't hit a wrong note, and you never have to stop and think. Flip on Auto Accompany and a rhythm section falls in behind you: bass and drums that follow every chord change you make, in styles from folk to funk to krautrock. One finger becomes a band. When something good happens, hit record. Loop, layer, and bounce it to audio, or export multi-track MIDI with chords, strum, bass, arpeggiator, and drums on separate tracks, ready for your DAW. In the studio, Polychord comes with you. The AUv3 MIDI-effect plugin puts the chord grid inside DAWs like Logic Pro that support MIDI effects, and MIDI in and out means it can play — or be played by — everything else you own. Whether you've played for twenty years or never learned an instrument, Polychord closes the gap between imagining music and making it. FEATURES • Nine chord circles covering the full harmony of any major or minor key • Chord palettes for folk, jazz, gospel, bossa nova, soul, cinematic, and more • Strum keys with pitch bend • Auto Accompany: bass lines and drum patterns that follow your chords • Arpeggiator with adjustable direction, rate, and octave span • Built-in wavetable synth with ADSR envelopes, filter, delay, and bitcrusher • Record performances and bounce to audio • Multi-track MIDI export: chords, strum, bass, arpeggiator, and drums on separate tracks • MIDI out to any app or hardware; MIDI in to trigger chords from a keyboard • You can even split your MIDI output to trigger multiple instruments at once in DAWs like Logic • AUv3 MIDI-effect plugin: play the chord grid inside your favorite host • AUv3 works in DAWs like Logic Pro that support MIDI effect plug-ins Polychord is a one-time purchase. No subscription, no in-app purchases, no account. Your music stays yours.

Read full description

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 call

The clearest difference is rating: EverSpace at 5.0 against Polychord's 4.4. EverSpace also leads on update cadence (weekly vs every 2 months) and price ($7.99 vs $9.99). Polychord's advantage is ratings volume (39 vs 1). On ads, in-app purchases, monetization model and iOS requirement there is nothing between them.
