Pegboard is a mobile synth designed to make playing music more intuitive. The app is a full-featured mobile subtractive synthesizer with a virtual analog filter. Use it as a melody writing app, music scale finder, or just as a MIDI keyboard controller. How you use it is completely up to you. The keyboard is arranged in a harmonic table layout. Scales you choose are highlighted for easy improvisation. Each chord has a simple shape that is the same in every key. This layout greatly simplifies playing chords, borrowing chords, and modulating between keys. Music theory apps tend to impose constraints and can be uninspiring. Pegboard will give you an intuitive feel for harmony and allow you to come up with your own amazing riffs all through improvisation. Most of the app features are free. The synth is fully playable and programmable in the free version. Included in the free version: • Over 400 unique scales. • 70 factory presets. • 8-voice polyphony. • 4 oscillators. • 7 effect modules. • 16-row modulation matrix. • Unlimited use, no ads. Included in the pro version: • Unlimited saved presets. • MIDI over USB. The pro version is available as an in-app purchase. It will allow you to use the app as a MIDI controller. You can then connect the app to your DAW or another synthesizer.

RRS Ivoks AUv3 instrument — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the RRS Ivoks AUv3 instrument as many times as you want, thereby you get the Demo period again and again.) Unlimited version of RRS Ivoks AUv3 instrument comes as In-App Purchase. Features: • Analog Emulation; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Scalable GUI. On the centre panel are located two audio-frequency oscillators: • OSC1 offers frequency Band regulator, five Waveforms and controls for LFO Modulation level plus OSC2 Cross-modulation; • OSC2 offers the same frequency Band and Waveforms, an independent control for Modulation depth, plus Detuning. Underneath these located the mixer, which offers level controls for the two Oscillators, the Noise generator, and Saturation Drive. To the right of these, located the filter block. The top half is a standard ADSR envelope — until you flip the switch «Envelope mode», when it becomes a repeating AD-envelope instead. The four controls at the bottom adjust Cut-off, Resonance, LPF to BPF switch, Modulation level and Envelope level. Next after the filter is the amplifier block, it also has ADSR envelope along with another Modulation level and Velocity sensitivity control. Again, the envelope can be switched to a Repeating Mode that generates a triangular waveform determined by the Attack and Decay settings, providing some of the instrument’s most distinctive effects. The leftmost panels house the Modulation (LFO) controls (top), Mode which offers four waveforms, including noise, and a stepped Function for sample & hold (S&H) effects, well as Speed control. And global settings such as the master Tune, master Volume, Legato mode, Monophonic and Duophonic operation and Unison switches, and the Glide control. To use Ivoks as an instrument, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — RRS Ivoks will appear in the list of Audio Unit instruments in the host app. MIDI CC Implementation Chart: • CC#003 => HQ • CC#009 => Saturation Drive • CC#014 => Modulator Speed • CC#015 => Modulator Mode • CC#020 => Filter Attack • CC#021 => AMP Attack • CC#022 => Filter Decay • CC#023 => AMP Decay • CC#024 => Filter Sustain • CC#025 => AMP Sustain • CC#026 => Filter Release • CC#027 => AMP Release • CC#028 => Filter Envelope Mode • CC#029 => AMP Envelope Mode • CC#030 => OSC1 Band • CC#031 => OSC2 Band • CC#085 => OSC1 Waveform • CC#086 => OSC2 Waveform • CC#087 => OSC1 XMod • CC#089 => OSC2 Detune • CC#090 => MOD to OSC1 • CC#102 => MOD to OSC2 • CC#103 => OSC1 Level • CC#104 => OSC2 Level • CC#105 => Noise Generator • CC#106 => Global Tune • CC#107 => Global Glide • CC#108 => Global Volume • CC#109 => Global Voice • CC#110 => Global Unison • CC#111 => Global Retrig • CC#112 => Filter Cut-off • CC#113 => Filter Resonance • CC#114 => Filter Mode • CC#115 => MOD to Filter • CC#116 => Filter Envelope • CC#117 => MOD to AMP • CC#118 => Velocity Sensitvity

Verdict
The clearest difference is ratings volume: RRS Ivoks at 45 against Pegboard's 9. RRS Ivoks also leads on iOS requirement (10.0 vs 15.0). On price, rating, review sentiment and update cadence 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
Both are free to download. Pegboard sells 1 one-off in-app purchase and RRS Ivoks sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.3 for Pegboard against 4.4 for RRS Ivoks. That said, the two scores are not equally well evidenced: RRS Ivoks has 45 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 56% of Pegboard's written reviews are positive against 63% of RRS Ivoks's.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 11, 2026 and August 26, 2026 respectively.
