Verdict
The clearest difference is in-app purchases: SAA at none against DrPhos Science Calculator's 10. SAA also leads on iOS requirement (15.0 vs 18.5). DrPhos Science Calculator's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
