Verdict
The clearest difference is price: Quad Calcs at Free against Source Edit's $0.99. Quad Calcs also leads on update cadence (every 2 weeks vs every 132 months) and iOS requirement (15.8.3 vs 18.5). Source Edit's advantage is ads (none vs shown) and chart position (#34 vs unranked). On in-app purchases and device support there is nothing between them.
