# Alder Security vs ADT+

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).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
