Verdict
The clearest difference is in-app purchases: Andon Vend at none against Calculator's 1. Andon Vend also leads on ads (none vs shown) and update cadence (every 2 weeks vs monthly). Calculator's advantage is iOS requirement (11.0 vs 18.0). On price and device support there is nothing between them.
