Verdict
The clearest difference is price: Calndars at $3.99 against Fabrication Calculator's $14.99. Calndars also leads on update cadence (every 5 weeks vs every 34 months). Fabrication Calculator's advantage is iOS requirement (16.1 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
