Verdict
The clearest difference is rating: ADT+ at 4.8 against Alder Security's 2.1. ADT+ also leads on review sentiment (41% vs 6%) and update cadence (monthly vs every 6 months). Alder Security's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
