BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.

SpectralLab

SpectralLab is a hands-on toolkit for spectral harmony in the Grisey/Murail tradition. Explore the harmonic series as a playable drone, record or import real sound and decompose it into its partials with on-device FFT analysis, then sculpt spectral chords with breathing LFOs and a Hammond-style drawbar interface — sounded either through a pure additive synth or a 16-band EQ run through your own recording. Chain chords into step sequences, export MIDI with microtonal pitch bend preserved, and study the technique through interactive references to the composers who pioneered it — tap "Try it" on Stockhausen, Grisey, Scelsi, or throat-singing tradition and hear the idea instantly, not just read about it. Whether you're a composition student studying spectral music or a sound designer who wants to hear harmonic ratios instead of just reading about them, SpectralLab turns the math of the overtone series into something you can see, hear, and play. • Harmonic series visualizer with true-pitch playback against a drone • Record/import audio, analyzed via on-device FFT — no data ever leaves your device • Drawbar chord builder: True Harmonic vs. Equal Temperament A/B toggle • Per-partial LFOs, pencil-draw mode, and a live harmonograph-style visualization • Step sequencer for chord progressions, synth or real-audio EQ playback • Standard MIDI export with pitch bend preserving true tuning • Theory tab: interactive references to Stockhausen, Grisey, Murail, Scelsi, Harvey, Partch, and more

Verdict
The clearest difference is chart position: BLEASS Granulizer at #181 against SpectralLab's unranked. BLEASS Granulizer also leads on iOS requirement (12.0 vs 18.0). SpectralLab's advantage is price ($4.99 vs $6.99). On ads, in-app purchases and device support there is nothing between them.
