Verdict
The clearest difference is rating: iNavX at 4.8 against Sailmate's 3.0. iNavX also leads on review sentiment (44% vs 17%) and ratings volume (22K vs 1). Sailmate's advantage is ads (none vs shown) and iOS requirement (9.0 vs 13.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
