The clearest difference is in-app purchases: Field Technician App at none against HVAC Tech Assistant's 3. Field Technician App also leads on iOS requirement (13.0 vs 26.2). HVAC Tech Assistant's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
