Verdict

The call

The clearest difference is price: P&O Comet at Free against PalpationMapp's $14.99. P&O Comet also leads on update cadence (every 4 months vs every 17 months) and iOS requirement (11.0 vs 14.0). PalpationMapp's advantage is rating (4.6 vs 4.0) and ratings volume (83 vs 3). On ads, in-app purchases and device support there is nothing between them.
