The clearest difference is rating: Proceq GPR Subsurface at 5.0 against Emlid Flow's 3.9. Proceq GPR Subsurface also leads on in-app purchases (none vs 1). Emlid Flow's advantage is update cadence (every 10 days vs every 3 months) and ratings volume (37 vs 3). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Emlid Flow sells 1 in-app purchase, starting at $24.99 per month. Proceq GPR Subsurface asks for nothing beyond the download.

Proceq GPR Subsurface holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Emlid Flow has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 55% of Emlid Flow's written reviews are positive against 50% of Proceq GPR Subsurface's, so the app with the better star average is not the one people write more warmly about.
