Verdict
The clearest difference is in-app purchases: HumanController at none against SmartTub's 1. HumanController also leads on review sentiment (100% vs 71%) and iOS requirement (14.0 vs 16.6). SmartTub's advantage is ads (none vs shown) and update cadence (every 5 months vs every 32 months). On price and device support there is nothing between them.
