Verdict
The clearest difference is price: UTCal at Free against Piping DataBase's $3.99. UTCal also leads on update cadence (fortnightly vs every 4 months). Piping DataBase's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 17.6). On ads and device support there is nothing between them.
