Verdict
The clearest difference is rating: Stack Up Skills at 5.0 against RefHQ's 4.5. Stack Up Skills also leads on review sentiment (100% vs 67%). RefHQ's advantage is update cadence (every 2 weeks vs monthly) and ratings volume (11 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
