Security controls prevent un-authorized access to a lighting system.

Verdict
The clearest difference is price: ArchMM at Free against iRFR's $49.99. ArchMM also leads on update cadence (every 2 weeks vs every 10 months). iRFR's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 18.0). On ads and in-app purchases there is nothing between them.
