Verdict
The clearest difference is in-app purchases: RekersSimplyConnect at none against APEXpulse Battery Control's 1. RekersSimplyConnect also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.0). APEXpulse Battery Control's advantage is update cadence (every 6 days vs every 15 months). On price and ads there is nothing between them.
