Verdict

The call

The clearest difference is ratings volume: Google Drive at 7.8M against Contacts Sync's 15K. Google Drive also leads on rating (4.8 vs 4.6) and chart position (#8 vs unranked). Contacts Sync's advantage is review sentiment (78% vs 65%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Contacts Sync sells 7 in-app purchases, starting at $1.99 per 7 days and Google Drive sells 9 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Google Drive holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Google Drive has 7.8M ratings behind it against 15K, so its average is the more settled of the two. Written reviews complicate that: 78% of Contacts Sync's written reviews are positive against 65% of Google Drive's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Contacts Sync ships an update every 5 days, Google Drive weekly. Both last shipped on September 24, 2026.
