Verdict
The clearest difference is in-app purchases: Undecuple Calc at none against Monarch Bell Schedule's 1. Undecuple Calc also leads on update cadence (every 2 weeks vs every 2 months). Monarch Bell Schedule's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.8.3). On price and device support there is nothing between them.
