# Contacts+ | Address Book vs cSync

The clearest difference is rating: cSync at 5.0 against Contacts+ | Address Book's 4.5. Contacts+ | Address Book's advantage is ratings volume (5.8K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Contacts+ | Address Book sells 8 in-app purchases, starting at $9.99 per month and cSync sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
