Verdict

The call

The clearest difference is in-app purchases: Firefox Focus at none against UC Browser's 17. Firefox Focus also leads on ads (none vs shown) and rating (4.7 vs 4.4). UC Browser's advantage is chart position (#130 vs unranked) and review sentiment (74% vs 63%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. UC Browser sells 17 in-app purchases, starting at $0.99 per 7 days. Firefox Focus asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Firefox Focus holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Firefox Focus has 82K ratings behind it against 4.9K, so its average is the more settled of the two. Written reviews complicate that: 74% of UC Browser's written reviews are positive against 63% of Firefox Focus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UC Browser ships an update fortnightly, Firefox Focus monthly. Both last shipped on September 25, 2026.
