A tiny solar system that plays piano. Four orbs, a gravity well, and walls that ring like bells. Fling an orb and it falls, ricochets, and plays notes. Where it hits a wall decides what it plays; the physics decide when. You don't write the music. You build a small world and curate what it sings. Gravity is a touch instrument first. Grab an orb and it follows your finger; let go and the throw becomes its velocity. Drag the gravity well and every orbit in the room bends. Set Pulse and the well breathes in time with the tempo, so chaos starts keeping a schedule. EVERYTHING LANDS IN KEY Every impact point along the boundary maps to a note of the current scale, low at one end, high at the other. Pick from 16 scales and 11 tuning systems (12-TET, just intonation, maqam, shruti and more). The scale strip along the bottom is a key-change timeline: tap a segment, change the key, and the whole world modulates on the bar. EIGHT WORLDS TO BOUNCE IN Rectangle, circle, triangle, hexagon, pentagon, octagon, diamond, star. Sharp corners ricochet hard and play jagged. Round shapes glide and play smooth. SOUND A 16-voice pluck engine through a double-bass body and reverb. Octave, key range, quantize from 1/32 to 1/2, orb-to-orb collisions on or off. Presets to start from, themes for the visuals. AUv3 AND STANDALONE Use Gravity full-screen as a standalone instrument, or load it as an AUv3 in GarageBand, AUM, Logic Pro, Cubasis, Loopy Pro and any other Audio Unit host. Each orb has its own MIDI channel, so Gravity can drive other instruments in your host. ONE PRICE No account, no ads, no in-app purchases, no data collected. Buy it once and it's yours. The same engine ships as a VST3 and AU plugin for Windows and macOS at touchmachines.com.
Phase Garden
Read full descriptionHide full description
Phase Garden takes the familiar sound of a phaser and lets it grow wild. Instead of relying on a single repeating sweep, Phase Garden uses three independent phaser voices moving together as a constantly evolving network. Each voice has its own modulation relationship, sweep behavior, feedback character, and stereo position. At restrained settings, Phase Garden creates smooth, dimensional movement that can add life to synths, guitars, pads, drums, vocals, and complete mixes. Increase Spread and the voices begin separating into a wider, more complex field. Add Drift and their relationships slowly evolve over time. Then there’s Wild. Wild introduces occasional controlled disturbances into the garden. A voice may change pace, alter its sweep, become more prominent, or temporarily move away from the others before settling back into the larger pattern. The result is phasing that doesn't feel locked to a perfectly repeating modulation cycle. Phase Garden can be subtle, spacious, liquid, hollow, tangled, resonant, unstable, or gloriously overgrown—but it always remains recognizably a phaser. Three phasers grow from the same source. None of them behave exactly alike. Plant a phase. Let it wander. Features Three independent phaser voices Evolving multi-phaser architecture Smooth organic modulation drift Controlled unpredictable behavior Adjustable separation between phaser voices Integrated stereo movement Resonant feedback from subtle to aggressive Wide range from gentle movement to tangled phase textures Factory presets ranging from restrained to overgrown

Verdict
The clearest difference is price: Phase Garden at $2.99 against Gravity Machine's $9.99. On ads, in-app purchases, device support and iOS requirement there is nothing between them.
