Verdict
The clearest difference is price: CMC Field Guide at Free against Pump Pressure's $1.99. CMC Field Guide also leads on rating (4.0 vs 3.0) and ratings volume (24 vs 2). Pump Pressure's advantage is update cadence (every 5 days vs every 3 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
