Verdict

The call

The clearest difference is rating: Focus at 4.7 against QuickSource's 3.3. Focus also leads on ratings volume (5.2K vs 3). QuickSource's advantage is iOS requirement (11.0 vs 13.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. QuickSource sells 1 one-off in-app purchase and Focus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Focus holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: Focus has 5.2K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of QuickSource's written reviews are positive against 54% of Focus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

QuickSource ships an update monthly, Focus every 3 weeks. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
