Interfere is an iOS-exclusive generative drawing tool for creating mesmerising Moiré patterns, interference structures, entangled geometries, and algorithmic artworks. Instead of drawing lines manually, you shape evolving geometries through an interactive generative system. Add and move control points across the canvas while the engine continuously generates layered variations, emergent structures, and flowing interference patterns. Interfere combines tactile interaction with controlled randomness, allowing every composition to evolve in unexpected ways while remaining fully explorable and editable. Features: • Create generative Moiré and interference patterns • Control line density, curvature, randomness, spacing, and thickness • Move, add, and remove control points in real time • Export high-resolution JPG images and vector graphics • Continue your work in Illustrator, Photoshop, or 3D software • Designed for artists, designers, illustrators, tattooists, and experimental creators Interfere can also be used as an educational and exploratory tool for studying interference phenomena, optical illusions, repetition, and emergent visual structures inspired by mathematics, geometry, and generative art. – Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is monetization model: Metadata at free with in-app purchases against Interfere's subscription. Metadata also leads on ratings volume (221 vs 14). Interfere's advantage is rating (4.5 vs 4.0) and update cadence (every 9 days vs every 4 months). On price, ads, in-app purchases and device support 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
Both are free to download. Metadata sells 1 in-app purchase, starting at $0.99 per month and Interfere sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Interfere holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Metadata has 221 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 24% of Metadata's written reviews are positive against 50% of Interfere's.
Metadata ships an update every 4 months, Interfere every 9 days. The most recent releases landed on October 10, 2026 and September 30, 2026 respectively.
