VOSC is best understood as a visual analogue of a traditional sound synthesizer. The medium of synthesis, rather than sound waves, is a vast quantity of on screen particles. By manipulating the size, shape, and frequency of the oscillators, an endless variety of moving patterns and textures can be created. A primary mechanism at work in VOSC is the phenomenon of visual harmony as explored by the computer graphics pioneer and visual artist John Whitney in the mid 20th century. The oscillators of VOSC operate in accordance with Whitney's principle of differential motion, giving rise to harmonic resonances as their frequencies move across whole ratios.

Verdict
The clearest difference is review sentiment: QR machine at 100% against VOSC Visual Particle Synth's 62%. QR machine also leads on rating (5.0 vs 4.5). VOSC Visual Particle Synth's advantage is price ($4.99 vs $9.99) and ratings volume (27 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
VOSC Visual Particle Synth costs $4.99 and QR machine $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
QR machine holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: VOSC Visual Particle Synth has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 62% of VOSC Visual Particle Synth's written reviews are positive against 100% of QR machine's.
