D-Chorus is a BBD-style spatial chorus for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. Designed for width with minimal audible pitch wobble, D-Chorus combines very slow, shallow modulation with opposite-phase left and right movement. Its four modes range from subtle widening to a deep, expansive chorus that feels more like space than an obvious sweep. FEATURES - Four vintage spatial-chorus modes - Opposite-phase left and right modulation - Equal-power Depth dry/wet blending - Width control from mono to hyper-wide - Adjustable input gain from -12 to +12 dB - BBD-style delay and compander behavior - Optional 2x and 4x oversampling - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use, shared between the standalone app and AUv3 extension. Demo time advances only while audio is actively processing. A one-time, non-consumable In-App Purchase unlocks unlimited use in both formats. Restore Purchases is available in the standalone app. D-Chorus is suited to synthesizers, guitars, vocals, electric piano, and pads that need stable dimension and stereo depth.

ScopeNode is a multi-input oscilloscope, capable of visualizing multiple tracks layered on top of each other. The plugin features a suite of phase alignment tools built around an interactive visual workflow tailored specifically for the low end. These can help eliminate low-frequency clashes at the source so your tracks layer perfectly without heavy reliance on aggressive sidechain dips. The result is a much smoother, more fluid bass response. Beyond phase alignment, ScopeNode is perfect for visualizing how individual components line up, checking delays between signal points, or analyzing precise pre and post waveform differences across third-party plugins or subchains. FEATURES: - Free-Running & Beat-Synced Modes - 4-Layer Scope Matrix + Live Summing: Layer up to four audio tracks simultaneously with a real-time composite summing view for instant clash detection - Separate controls for visualization and sum inclusion to accommodate special use cases (optional) - Phase shifter with configurable center frequency and Q factor (one per track) - Sample grid delay, phase invert, gain control also available for each track - Multi-instance workflow: Drop plugin instances ("probes") anywhere in your signal paths to capture and compare tracks instantly TECHNICAL NOTES: - When enabled, it's recommended to verify that Plug-in Latency Compensation is not affecting synchronization in unexpected ways with the given set of active third-party plugins - Manual phase alignment is an advanced, hands-on process that requires time and active engineering effort, depending on the complexity of the tracks involved - Workflows could be greatly impacted by specific features of your DAW, e.g. ease of automation envelope editing, ways of laying out multiple viewports, etc. PLEASE NOTE: โข An AUv3-compatible host is required to use this app (true interoperability can vary across different apps) โข Please check our support page for a list of compatible host applications โข Officially supported sampling rates: 44.1, 48, 96 kHz

Verdict
The clearest difference is price: D at Free against ScopeNode's $4.99. ScopeNode's advantage is in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
