# ETC Library vs ProductionPro

The clearest difference is review sentiment: ProductionPro at 60% against ETC Library's 0%. ProductionPro also leads on ratings volume (43 vs 4) and update cadence (every 5 weeks vs every 3 months). ETC Library's advantage is rating (3.8 vs 3.3) and in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. ProductionPro sells 1 in-app purchase, starting at $19.99 per month. ETC Library asks for nothing beyond the download.

ETC Library holds the better App Store score, 3.8 against 3.3. That said, the two scores are not equally well evidenced: ProductionPro has 43 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of ETC Library's written reviews are positive against 60% of ProductionPro's, so the app with the better star average is not the one people write more warmly about.

ETC Library ships an update every 3 months, ProductionPro every 5 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
