Verdict
The clearest difference is update cadence: Hole Volumes at every 5 months against Directional Survey Methods's every 50 months. Directional Survey Methods's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
