# PIX4Dcatch vs Propeller Mobile

The clearest difference is rating: PIX4Dcatch at 4.7 against Propeller Mobile's 4.2. PIX4Dcatch also leads on ratings volume (262 vs 10). Propeller Mobile's advantage is in-app purchases (none vs 1) and iOS requirement (16.1 vs 18.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. PIX4Dcatch sells 1 in-app purchase, starting at $159.00 per month. Propeller Mobile asks for nothing beyond the download.

PIX4Dcatch holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: PIX4Dcatch has 262 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 33% of PIX4Dcatch's written reviews are positive against 40% of Propeller Mobile's, so the app with the better star average is not the one people write more warmly about.

PIX4Dcatch ships an update fortnightly, Propeller Mobile every 2 weeks. The most recent releases landed on September 24, 2026 and September 13, 2026 respectively.
