# Metadata vs Interfere

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.

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.
