Verdict

The call

The clearest difference is in-app purchases: Trace Note at none against Calculator #'s 6. Trace Note also leads on ads (none vs shown) and update cadence (every 6 days vs every 2 months). Calculator #'s advantage is device support (3 vs 1) and iOS requirement (12.1 vs 18.0). On price there is nothing between them.
