# Connect2Concepts vs Zotero

The clearest difference is ratings volume: Zotero at 435 against Connect2Concepts's 12. Zotero also leads on rating (4.6 vs 4.4) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Zotero holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Zotero has 435 ratings behind it against 12, so its average is the more settled of the two.
