Verdict
The clearest difference is in-app purchases: NFC Reader & Writer at none against SiteUp's 1. NFC Reader & Writer also leads on chart position (#88 vs unranked) and iOS requirement (17 vs 26.0). SiteUp's advantage is update cadence (every 2 days vs every 2 weeks). On price, ads and device support there is nothing between them.
