# IBackup vs Contacts Sync

The clearest difference is update cadence: Contacts Sync at every 5 days against IBackup's every 2 months. Contacts Sync also leads on ratings volume (15K vs 181). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. IBackup sells 1 one-off in-app purchase and Contacts Sync sells 7 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
