# SurveyingMaster vs PIX4Dcatch

The clearest difference is rating: PIX4Dcatch at 4.7 against SurveyingMaster's 3.5. PIX4Dcatch also leads on update cadence (every 2 weeks vs every 7 months) and ratings volume (266 vs 2). SurveyingMaster's advantage is monetization model (free vs free with in-app purchases) and review sentiment (50% vs 33%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SurveyingMaster sells 2 one-off in-app purchases and PIX4Dcatch sells 1 in-app purchase, starting at $159.00 per month. Whichever you choose, the download price is not the number that matters.

PIX4Dcatch holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: PIX4Dcatch has 266 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of SurveyingMaster'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.

SurveyingMaster ships an update every 7 months, PIX4Dcatch every 2 weeks. The most recent releases landed on October 1, 2026 and October 24, 2026 respectively.
