# Proceq GPR Subsurface vs Moasure

The clearest difference is rating: Proceq GPR Subsurface at 5.0 against Moasure's 4.0. Moasure's advantage is update cadence (every 8 days vs every 3 months) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Proceq GPR Subsurface holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Moasure has 126 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Proceq GPR Subsurface's written reviews are positive against 72% of Moasure's, so the app with the better star average is not the one people write more warmly about.

Proceq GPR Subsurface ships an update every 3 months, Moasure every 8 days. The most recent releases landed on September 15, 2026 and September 22, 2026 respectively.
