Verdict
The clearest difference is in-app purchases: Time Duration/Add Calculator at none against Real PIN's 1. Time Duration/Add Calculator also leads on iOS requirement (13.0 vs 18.0). Real PIN's advantage is ads (none vs shown) and update cadence (fortnightly vs every 9 months). On price and device support there is nothing between them.
