ShockWave is a monophonic Synthesizer designed to bring modular style workflow to the world of iOS & AUv3 plugins. Built around the concept of Phase Distortion (PD) Synthesis, Shockwave includes a pair of PD Oscillators each capable of creating everything from pure Sine Waves over smooth Sawtooth and Square Waves to Resonance & Sync sweeps, filtered Noise and more. In addition to the Synth Voice, ShockWave includes a dedicated control section housing a pair of 8 step sequencers, a sample & hold module as well modules for trigger divisions, logic comparisons and controlled randomness. A pair of Low Frequency Oscillators and 2 Attack/Sustain/Release (ASR) Envelopes serve as main modulation sources and can be used in a number of ways. Envelopes can be triggered from a number of internal sources including other modules such as trigger divider, logic or chance module but can also be connected to each other allowing for a wide range of patches usually only possible in large modular systems. LFOs are individually tempo sync-able and capable of producing total of 5 different waveforms each. The two sequencers can run independently or combine to one 16 step sequence where rate and length can be controlled independently for each of the two. In true modular nature almost any control within ShockWave can be modulated with up to 11 sources - simultaneously. Modulations are setup simply by holding a control and dialling in the desired amount in a list of all available sources. A special X-Ray mode adds a realtime display of all currently active modulations right at their corresponding control making it easy to understand what's happening inside the synthesizer at any given time. Synth Voice and Control Section are accompanied by built-in Delay and Reverb sections placed on send busses with all of their controls including the send levels being available as mod destinations. Last but not least, ShockWave features a solid MIDI implementation including support for, aftertouch, velocity, wheels, custom CC mappings and up to 4 dimensions of expression when using MPE compatible controllers, such as the Roli Seaboard, Linnstrument, Geoshred, KB-1 and others. MIDI Output is supported as well and includes Note and Control Change output generated from various internal sources including Sequencers, Envelopes and LFOs making it possible to control external MIDI gear or chain multiple plugin instances for advanced, self driving patches.

WoodSynth is a synthesizer with 4 independent layers. Each layer is in fact a synthesizer on its own. Each layer has 3 VCO’s plus a samples or wavetable based source, coming from a file or from recording the audio track. Up to 16 voices can be set per layer. Layers can be used in parallel, assigned to a region of the keyboard or used in a sequential mode where the first note(s) on are played by layer 1 and the next note(s) by layer 2 and so on. This last mode allows to have a different sound per note played (and independent from a keyboard region). WoodSynth has a polyphonic pitch-bending touch bar which also displays notes received from a keyboard. Each layer has its own filter and envelope with ADSR per voice, a pitch shifting envelope per VCO, a delay, a basic reverb, a modulator LFO per VCO, 2 general LFO’s and a 16 steps sequencer. Key tracking can be applied on the ADSR attack and release, on the filter cutoff and on the VCO modulation. The app can be used stand-alone (device audio input and output) or as a plugin in a DAW. - IOS plugin type : AUv3 and stand-alone app. - Has 4 independent synthesizers, each with up to 16 voices. - Supports MPE and Midi V2. - Has a polyphonic touch bar with polyphonic pitch bending. - Velocity, channel pressure, (polyphonic) aftertouch, CC74 can be used to modulate several synth parameters. - VCO’s have the usual waveforms (sine, saw, square, triangle, pulse and noise) and can be modulated in various ways (FM, AM, Pulse Width, Slew rate) - Samples can be recorded from the audio input/track or loaded from file (sample files should be in the WoodSynth iCloud folder) - Wavetables can be loaded from file or converted from loaded or recorded samples. - Each voice has a 4-pole Moog Lowpass filter with resonance and ADSR envelope. - An offset can be set in the Filter cutoff for the R channel to create a stereo effect. - Each voice has a pitch shifting ADSR envelope which can be independently enabled for each VCO. - Has Key tracking for VCO pan, Filter cutoff, ADSR Envelope Attack and Release. - Each layer has a delay unit (which can be separately panned) and a basic reverb. - Each layer has a 16 steps sequencer which can run on multiple voices (poly mode). - Each layer can set the midi channel and range of receiving midi notes (which allows for up to 4 split keyboard regions). - Layers can be set in sequential mode : first note(s) played on layer1, next note(s) on layer2, etc. - Layers have an additional high-pass filter saturation and crush control. - Synth audio and delay can be panned independently. - The 2 general LFO’s can have their source from the samples or wavetables (or track input). - Supports Ableton Link to sync tempo and start-stop. - Has 4 User Control rotaries which can be freely assigned. - The User Controls can be controlled by a midi CC which can be set or learned. - Presets can be stored in iCloud Drive (makes them available on all your devices). - Supports CV out and Sequencer Midi out.

Verdict
The clearest difference is rating: ShockWave at 4.6 against WoodSynth's 4.0. ShockWave also leads on ratings volume (190 vs 27). WoodSynth's advantage is price ($15.99 vs $19.99). On review sentiment, update cadence, ads and in-app purchases 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
ShockWave costs $19.99 and WoodSynth $15.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ShockWave holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: ShockWave has 190 ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 53% of ShockWave's written reviews are positive against 60% of WoodSynth's, so the app with the better star average is not the one people write more warmly about.
ShockWave ships an update every 2 months, WoodSynth every 5 weeks. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
