Verdict
The clearest difference is rating: CalcFast at 4.2 against SanpSave's 1.0. CalcFast also leads on in-app purchases (none vs 2) and ratings volume (21 vs 1). SanpSave's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (16.0 vs 27.1). On price, ads and device support there is nothing between them.
