SignatureDYN - Compressor / Gate / Limiter SignatureDYN is a professional 3-in-1 dynamics processor for iPhone and iPad. It combines a peak compressor, a smooth noise gate, and a brick-wall limiter in a single AUv3 plugin - covering the complete dynamics processing chain in one insert slot. Compressor Hard-knee peak compressor with independent attack and release. Threshold from โ60 to 0 dB, ratio from 1:1 to 20:1. Transparent at low ratios, aggressive at high ratios. Gate Exponential noise gate with smooth closing - 3ร slower than opening to avoid clicks and unnatural cutoffs. A dedicated LED indicator lights when the gate is active, making threshold setting precise and visual. Limiter Brick-wall output limiter with fixed 0.1 ms attack. No signal exceeds the set ceiling. Release follows the compressor release time. Default ceiling โ0.3 dB โ transparent protection always on. Metering Real-time Input VU meter and Gain Reduction meter with dB scale. Signal presence LED. Features AUv3 Audio Unit Extension - loads in AU EngineCore and any AUv3 compatible host Zero latency Full parameter automation Responsive UI - iPhone and iPad, portrait and landscape 7 automatable parameters: Threshold, Ratio, Attack, Release, Makeup Gain, Gate, Limiter #nobodysbanda
LogSynth

LogSynth is a polyphonic virtual-analog synthesizer built for people who care what's actually happening in the signal path, not just what the preset browser looks like. Every voice runs five anti-aliased oscillators (sine, triangle, saw, pulse with PWM, and a band-limited impulse train) plus a dedicated sub-oscillator and noise source, mixed per-voice with independent amp envelopes. Chunky oscillators, crisp effects and a zero-delay-feedback state-variable filter โ switchable low/high/bandpass. The drive effect is powered by a physically modeled diode circuit, numerically integrated rather than a lookup-table approximation, so pushing it into saturation behaves the way an actual analog drive would. FEATURES - 8-voice polyphony, 5 oscillators + sub + noise per voice - Zero-delay-feedback state-variable filter with resonant feedback and diode drive saturation - 5 independent oscillator envelopes plus a dedicated filter envelope - 2 assignable LFOs and an 8-slot modulation matrix - Built-in chorus, delay, FDN reverb, and 4-mode distortion - 41 factory presets across Bass, Lead, Pluck, and Effects - One-tap patch randomizer with adjustable intensity - Real-time oscilloscope, on-screen keyboard, and CoreMIDI input - Runs standalone or as an AUv3 instrument inside AU hosts Whether you're sound designing from scratch or dropping it into a DAW as a plugin, Logsynth gives you the same engine everywhere โ no watered-down mobile version, no feature gating between standalone and plugin modes.

Verdict
The clearest difference is price: SignatureDYN at $5.99 against LogSynth's $9.99. SignatureDYN also leads on iOS requirement (15.0 vs 18.0). On update cadence, ads, in-app purchases and device support there is nothing between them.
