The clearest difference is in-app purchases: Forest Watcher at none against Topo GPS's 22. Forest Watcher also leads on rating (5.0 vs 4.5) and review sentiment (80% vs 70%). Topo GPS's advantage is ratings volume (476 vs 8) and update cadence (every 3 weeks vs every 3 months). On price, ads and iOS requirement there is nothing between them.
