Verdict

The call

The clearest difference is rating: Sizing US/CA at 3.2 against Bryant® Service Technician's 2.4. Sizing US/CA also leads on iOS requirement (10.0 vs 15.1). Bryant® Service Technician's advantage is ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). On price, ratings volume, in-app purchases and device support there is nothing between them.
