Verdict
The clearest difference is in-app purchases: Zeno Connect at none against Topo Maps+'s 11. Zeno Connect also leads on iOS requirement (13.0 vs 17.0). Topo Maps+'s advantage is update cadence (every 3 weeks vs every 8 months) and review sentiment (62% vs 33%). On price, ads and device support there is nothing between them.
