Verdict
The clearest difference is in-app purchases: Field Tools at none against Mango Exposure's 1. Field Tools also leads on ratings volume (9 vs 1) and iOS requirement (12.0 vs 26.0). Mango Exposure's advantage is update cadence (every 2 weeks vs every 5 months). On price, rating, ads and device support there is nothing between them.
