Verdict
The clearest difference is in-app purchases: Expertens at none against Calculator X's 2. Expertens also leads on ads (none vs shown) and iOS requirement (12.0 vs 14.0). Calculator X's advantage is update cadence (every 3 weeks vs every 13 months). On price and device support there is nothing between them.
