Verdict
The clearest difference is price: Nautics Sailmate at Free against Topo Maps's $2.99. Nautics Sailmate also leads on iOS requirement (15 vs 17.6). Topo Maps's advantage is in-app purchases (none vs 1) and chart position (#130 vs unranked). On update cadence, ads and device support there is nothing between them.
