SKIIID vs isxynth
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SKIIID
This app is a percussion synthesizer designed for live performance. It features four morphing pads where finger position controls sound parameters and velocity. Explore deep sound design with a step sequencer, auto-mutation, and chaos engine for instant sound generation.
- Four morphing percussion pads
- Real-time parameter control via touch
- 16-step sequencer per pad
- Auto-mutate sound evolution
- Chaos engine for instant sound generation
- AUv3 plugin support
- MIDI input and Ableton Link sync

SKIIID is a percussion synthesizer built for real-time performance. Four pads. Each one is a sound sculpted by where your finger lands. Move left or right to morph between synth parameters. Move up or down to control velocity. Simple to play, deep to explore. — PADS — Four independent drum voices. Each pad morphs between parameter extremes based on X-axis position. Velocity is Y-axis. — STEP SEQUENCER — 16-step sequencer per pad. Variable step length for polyrhythms. Reverse playback, shuffle, pin and random step modes. Sync to Ableton Link or run free. — AUTO-MUTATE — Evolves your sound automatically. Individual interval and intensity per pad, synced to tempo. — CHAOS ENGINE — RANDOM, CHAOS, and MUTATE modes generate new sounds instantly. — AUv3 PLUGIN — Run SKIIID inside AUM, ApeMatrix, Audiobus, or any AUv3 host. Multiple instances work independently — different patches, different sequencers, no shared state. — MIDI — MIDI In for pad triggering. MIDI Learn for external controller mapping. Ableton Link for tempo sync. — WORKS ON — iPhone and iPad, all modern screen sizes. Landscape mode.
isxynth
This music effect plugin allows spectral cross synthesis and morphing between two input signals. It separates noise and tone components, offering controls for blending, freezing, and time-based delays. Gestures on controls can be recorded and played back for dynamic sound shaping.
- Spectral cross synthesis
- Morphing between two input signals
- Noise and tone component blending
- Freeze control for spectral blurring
- 3-second delay lines per input
- Gesture recording and playback

isxysnth is spectral cross synthesis / morphing plugin it gets two input signals, splits each one into 2 parts containing noise and tone components and then allows morphing between all these elements. Freeze control allows spectral blurring-like effect for both input signals, two 3 second delay lines allow selection of different signal in time and also provide "freeze" effect you can process left and right channels on stereo source or use this effect as multi-input AUv3 - in that case it will use 2 stereo inputs. Standalone mode currently works only in "mono" mode - three XY controls set balance between tone and noise components, amount of freeze and set up morphing - both inputs have 3-second delay line; freeze button ("*") toggles off recording. - gestures on all the main controls (3 xy pads and two sliders) can be recorded and played back when appropriate button with ">" label is toggled on - in current version standalone app supports only mono (L + R as inputs I and II) processing

Verdict
The clearest difference is rating: SKIIID at 4.4 against isxynth's 3.7. SKIIID also leads on update cadence (every 4 days vs every 34 months) and price ($3.99 vs $7.99). isxynth's advantage is review sentiment (100% vs 74%) and iOS requirement (11.0 vs 16.0). On ads, in-app purchases, monetization model and device support 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
SKIIID costs $3.99 and isxynth $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.
SKIIID holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: SKIIID has 31 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 74% of SKIIID's written reviews are positive against 100% of isxynth's, so the app with the better star average is not the one people write more warmly about.
SKIIID ships an update every 4 days, isxynth every 34 months. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
