Verdict
The clearest difference is rating: xDelete at 4.7 against Spool Ethanol Analyzer's 4.1. xDelete also leads on review sentiment (73% vs 40%) and update cadence (fortnightly vs every 13 months). Spool Ethanol Analyzer's advantage is monetization model (free vs paid) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
