# SurveyingMaster vs Emlid Flow

The clearest difference is update cadence: Emlid Flow at every 10 days against SurveyingMaster's every 7 months. Emlid Flow also leads on rating (3.9 vs 3.5) and ratings volume (37 vs 2). SurveyingMaster's advantage is monetization model (free vs freemium) and iOS requirement (8.0 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. SurveyingMaster sells 2 one-off in-app purchases and Emlid Flow sells 1 in-app purchase, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Emlid Flow holds the better App Store score, 3.9 against 3.5. That said, the two scores are not equally well evidenced: Emlid Flow has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of SurveyingMaster's written reviews are positive against 55% of Emlid Flow's.

SurveyingMaster ships an update every 7 months, Emlid Flow every 10 days. The most recent releases landed on October 1, 2026 and October 29, 2026 respectively.
