Verdict
The clearest difference is in-app purchases: EZDateCalc at none against FieldBus Toolkit's 1. EZDateCalc also leads on ads (none vs shown). FieldBus Toolkit's advantage is update cadence (every 2 months vs every 27 months) and iOS requirement (13.0 vs 16.0). On price and device support there is nothing between them.
