Verdict
The clearest difference is price: eVARMO at Free against OpenWebUI's $2.99. eVARMO also leads on iOS requirement (12.0 vs 17.0). OpenWebUI's advantage is update cadence (every 6 days vs every 7 months) and chart position (#80 vs unranked). On ads, in-app purchases and device support there is nothing between them.
