Verdict
The clearest difference is rating: Sum Quest at 5.0 against Calculator Quest's 4.1. Sum Quest also leads on update cadence (monthly vs every 4 months) and iOS requirement (11.0 vs 13.0). Calculator Quest's advantage is ratings volume (14 vs 1) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.
