# Document Manager + BizTools vs Eco Cat App

The clearest difference is price: Eco Cat App at Free against Document Manager + BizTools's $3.99. Eco Cat App also leads on review sentiment (88% vs 56%) and update cadence (fortnightly vs every 3 months). Document Manager + BizTools's advantage is rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.

Eco Cat App is free to download; Document Manager + BizTools costs $3.99 up front. Document Manager + BizTools sells 10 in-app purchases, starting at $39.99 per 3 months and Eco Cat App sells 5 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Document Manager + BizTools holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Eco Cat App has 2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of Document Manager + BizTools's written reviews are positive against 88% of Eco Cat App's, so the app with the better star average is not the one people write more warmly about.

Document Manager + BizTools ships an update every 3 months, Eco Cat App fortnightly. Both last shipped on October 24, 2026.
