Verdict

The call

The clearest difference is rating: PIX4Dcatch at 4.7 against Emlid Flow's 3.9. PIX4Dcatch also leads on ratings volume (262 vs 33). Emlid Flow's advantage is review sentiment (58% vs 33%) and iOS requirement (16.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PIX4Dcatch holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: PIX4Dcatch has 262 ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 58% of Emlid Flow's written reviews are positive against 33% of PIX4Dcatch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Emlid Flow ships an update every 10 days, PIX4Dcatch fortnightly. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
