Verdict
The clearest difference is ads: Relax Browser at none against Calc's shown. Relax Browser also leads on update cadence (every 2 days vs every 2 weeks). Calc's advantage is device support (3 vs 1) and iOS requirement (15.8.3 vs 17.0). On price and in-app purchases there is nothing between them.
