Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GSDSP Quantum Delay
This app offers a vintage-inspired stereo delay effect with advanced modulation, flexible filtering, and precise timing controls. It allows users to sculpt unique echo textures, from warm analog sounds to complex, evolving soundscapes.
- Vintage-inspired stereo delay
- Deep modulation system
- Flexible filtering (LPF, HPF, BPF)
- Precise timing controls (BPM, ms)
- Switchable stereo/dual mono modes
- Advanced modulation sources (LFO, Random, Envelope)

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. Classic Delay, Reinvented Quantum Delay takes the charm of a vintage stereo delay and fuses it with our next-level modulation system. Switch between the warm character of Tape mode and the pristine clarity of Fade mode, lock to BPM (including 5-tuplets) or dial in precise times in milliseconds. Use the Fine control for subtle push-and-pull micro-timing — or modulate your delay lines in ways traditional delays could only dream of. Sculpted Echoes Shape your repeats with switchable lowpass, highpass, and bandpass filters placed directly in the feedback path. Add modulation to create evolving tones, gentle movement, or drifting, frequency-shifting echoes. From warm analog-style rolls to shimmering, swirling textures, it’s all there. Feedback with Precision Control your delay tail behavior using either traditional % feedback or our modern dB-per-second decay system — ideal for predictable, musical decay even when the feedback path becomes complex. Enable Crossfeed for classic ping-pong stereo bounce, or push into Over-Feedback to create dense, self-building echoes that drift toward infinity. Stereo or Dual Mono Every section of Quantum Delay — delay, filter, and feedback — can switch between stereo and dual mono modes. Create tight, controlled stereo images or break them apart for wide, offset, unpredictable spaces. Dual mono modulation unlocks complex stereo interplay and beautifully asymmetric echoes. Modulation Without Limits Quantum Delay integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, stereo controls, and more. Use LFOs, Random Generators, 2D modulators, Envelope Followers, Macros, and even chaotic systems to push your echoes far beyond traditional delay behavior. Or use our parameter randomisation feature to explore the plugin’s sound at random. Quantum Delay is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX). More information here: https://gs-dsp.com/products
Things
This audio effect plugin allows users to creatively combine and manipulate two audio signals. It can be used for subtle sound morphing, rhythmic gating, adding vibrato, or extreme modulation effects.
- Side-chaining signal combination
- Volume and spatial position modulation
- Vibrato effect
- Extreme modulation speeds
- Sound morphing
- Rhythmic gating

Motor is a plugin effect that uses side-chaining to combine signals in new and interesting ways: put in any two signals and they will dance around each other like courting birds drunk on fermented cherries. Use it to gently morph between sounds or rhythmically cut them up, affecting both volume and spatial position. Add life to the plainest signals with vibrato, or destroy them in interesting ways with extreme modulation speeds.

Verdict
The clearest difference is price: Things at $6.99 against GSDSP Quantum Delay's $14.99. Things also leads on rating (5.0 vs 4.8). GSDSP Quantum Delay's advantage is update cadence (every 5 weeks vs every 24 months). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
