Verdict
The clearest difference is in-app purchases: CT at none against Global BioWatch's 1. CT also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.4). Global BioWatch's advantage is ads (none vs shown) and update cadence (weekly vs every 12 months). On price there is nothing between them.
