Verdict
The clearest difference is in-app purchases: IoT RTU at none against Modbus TCP Station's 2. IoT RTU also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). Modbus TCP Station's advantage is update cadence (every 10 days vs monthly). On price and device support there is nothing between them.
