Verdict
The clearest difference is ads: DevPro Light at none against Security Alarm's shown. DevPro Light also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Security Alarm's advantage is update cadence (every 3 weeks vs every 29 months). On price and in-app purchases there is nothing between them.
