Verdict

The call

The clearest difference is in-app purchases: Numby at none against CalcBin's 1. Numby also leads on ads (none vs shown) and update cadence (every 2 days vs every 6 months). CalcBin's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.6). On price there is nothing between them.
