Verdict
The clearest difference is in-app purchases: OK GlucoBlue at none against Sugar Smart's 2. OK GlucoBlue also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.0). Sugar Smart's advantage is update cadence (every 4 days vs every 2 months). On price and device support there is nothing between them.
