Ispín adds weight, warmth and grit to thin-sounding tracks. Push it gently for compression and glue, or drive it hard for full distortion. Four controls, no menus, nothing to set up. RICHNESS: Density and drive. Goes from subtle thickening to heavy saturation. COLOUR: Tilts the harmonics dark to bright, so the dirt sits where you want it. ROUGHNESS: Drives the waveform off-centre for buzz, grind and edge. OUTPUT: -18 to +6 dB of trim, for a level-matched A/B against your dry track. At zero, Ispín passes audio at unity gain — so bypass tells you what you added, not just what got louder. Six presets included: Grand So, A Bit of Dinner, The Crispy End, Hot Tea, Full Breakfast Consequences, and I Left the Immersion On. Save your own alongside them. The interface resizes to fit the space your host gives it, in portrait or landscape. Note: This is an Audio Unit Effect Plugin (AUv3), which requires a host such as AUM or Loopy Pro – or a DAW such as GarageBand, Logic Pro or Cubasis.

Granula is a granular synthesizer for the phone. It takes a sound from demo samples (like guitar, calimba, tongue drum, etc.) or thirty seconds you record on the spot and scatters it into hundreds of tiny overlapping grains. A slow, shifting texture comes back to your space: ambient pads, drones, atmospheres that keep evolving as long as you keep listening. Everything is played with your hands. The whole screen is a morph pad: move a finger across it and the sound moves with you, while a field of glyphs lights up under your touch and churns in time with what you hear. FOUR CHARACTERS • Reverse: short grains, played mostly backwards, with octave and fifth sparkles on top • Gater: a denser cloud chopped on a grid, from halves down to sixteenths • Chorus: long, slow, detuned grains with the read position drifting like a tide • Scatter: harmonic intervals thrown at random and sprayed wide FOUR KNOBS • Grain size, from 15 ms clicks to 1 second • Position: where in the sample the grains are lifted from • Density: from sparse drips to a solid wash • Dry/Wet: a six-second convolution reverb, plus the amount of reversed grains RECORD THE WORLD AROUND Hold the record button and capture up to thirty seconds of anything: your voice, a room, rain on a window, a string you plucked once. The take is granulated immediately and kept in your library under a name of its own. You can also import your own MP3 or WAV files. MADE FOR A PHONE • Keeps playing with the screen locked and in the background • Survives calls, headphone unplugs and output switches without losing your session • Any class-compliant USB or Bluetooth MIDI keyboard plays it - plug in and go, nothing to pair inside the app GRANULA PRO Every built-in sound is free and stays free. A free account also brings in one sound of your own - recorded or imported. Granula Pro lifts that limit: record and import as much as you like, and everything syncs to your account so a new phone picks up where the last one left off. No ads.

Verdict
The clearest difference is in-app purchases: Ispin Saturator at none against Granula's 1. On price, update cadence, ads and device support there is nothing between them.
