GliderVerb vs ShimmerVerb
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GliderVerb
This app offers a unique reverberation effect that simulates a room changing shape, creating evolving soundscapes. It provides a wide range of sonic possibilities, from smooth resonances to granular disintegration, with extensive control over its parameters.
- Continually modulated reverb algorithm
- Pitch resonator
- Ribbon resonance player
- Built-in stereo sampler
- Control manager LFO
- Audiobus and Inter-App Audio support
- Preset morphing pad

GliderVerb is a “Reverberator with Glissandos” simulating a room gradually changing its shape. It is an expanded version of an algorithm created by James McCartney for his Supercollider 2 programming language. The original algorithm had no user-variable parameters: this device adds a series of parameters to create a wide palette of effects; from evolving reverberations to granular disintegration to smooth resonances. Main Features: - Audiobus and Inter-App Audio support (sender and FX) - Continually Modulated Reverb Algorithm - Pitch Resonator - Ribbon Resonance Player - Pad impulse generator - Built In Stereo Sampler with varispeed - Control Manager LFO for Parameters - Midibus, Virtual Midi and Network: 14 bit NRPN controllers - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad - Post Fx Chain: Low-shelf Filter, High-shelf and Compressor New Version! We removed the "annoying voice" and now you can use all the Gliderverb features, even the Pad and the Ribbon. The only limitation is you can't save new presets; but you still can load the old ones you made, using the two arrows you find on the left and right side of the preset name (top side of the main window). With the in-App purchase you can access the Preset Manager, Control Manager and MIDI enable the Pad.
ShimmerVerb
This app creates massive, lustrous reverbs with parallel pitch shifters for ethereal, shimmering soundscapes. It offers advanced feedback control and performance-oriented features like a "Ribbon" macro and "HotSwitch" for dynamic sound shaping.
- Massive lustrous reverb with parallel pitch shifters
- Infinitely feedbackable signal for cascading reverbs
- Adjustable feedback frequencies via cross-over network
- Playable "Ribbon" performance macro
- Instant parameter switching with "HotSwitch"
- "Freeze" button for smeared textures
- AUv3 plugin and standalone app

ShimmerVerb combines a massively lustrous reverb with parallel pitch shifters to add ethereal layers making any signal, well, "shimmer." Oftentimes, producers would achieve the effect by using Eventide pitch shifting hardware such as the H910, H949, or H3000 or other rack mount units in combination with a reverb. This production technique was popularized by Daniel Lanois and Brian Eno on U2's The Unforgettable Fire. Now, this iconic sound has been refined and extended with a modern, unified interface that is great for adding dreamy ambiance to guitars, keys, synths, samples, and vocals. In typical Eventide fashion, features have been added such as the ability to infinitely feedback the signal, resulting in cascading reverbs that smear into oblivion. Feedback can be further fine-tuned by specifying which frequencies are fed back through the low/mid/high cross-over network. ShimmerVerb shines via its playable, performance-based parameters. "The Ribbon" is an easy to program performance macro allowing users to morph between two settings with one control. Desktop users can plug in a MIDI keyboard and gain tactile command over this function via the modulation wheel. Ribbon mappings are great for Feedback swells, moving the Pitch knobs, or changing the Size for a massive detuning result. ShimmerVerb also boasts a HotSwitch for calling up another state of parameters inside the same preset. Use this for changing octaves, turning off/on the pitch shifters, or simply turning the Mix up or down while crafting your performance. Finally, the Freeze button allows you to make smeared textures out of single voices, full pads, or percussive elements resulting in metallic "shimmers." Features: - Unique reverb plug-in with parallel pitch shifters on the reverb tail. - Easily pitch with perfect fourths, fifths, and octaves. - Micropitch tuning available around perfect intervals. - Four octaves of pitch shifting (from two octaves down to two octaves up). - Delay pitched signals up to one second or sync them to your DAW's tempo. - Feedback determines how much delayed signal is fed back into the input of the reverb. - Low, Mid, and High cross-over network determines which frequencies are fed back. - FREEZE holds the current state of the reverb in a smeared texture. - The RIBBON allows for real-time modification of several parameters at once. - HOTSWITCH allows for instant switching between two sets of parameters within one preset. - Available as an Audio Units AUv3 plug-in and Standalone App.

Verdict
The clearest difference is price: GliderVerb at Free against ShimmerVerb's $14.99. GliderVerb also leads on ratings volume (86 vs 12). ShimmerVerb's advantage is in-app purchases (none vs 2) and update cadence (every 6 weeks vs every 4 months). On rating, review sentiment, ads and device support there is nothing between them.
