Verdict
The clearest difference is in-app purchases: SimpleUnit Lite at none against Units Free's 1. SimpleUnit Lite also leads on update cadence (every 5 days vs every 5 months). Units Free's advantage is device support (3 vs 1) and iOS requirement (5.1.1 vs 16.0). On price there is nothing between them.
