Verdict
The clearest difference is review sentiment: Impact Scoring at 100% against XFR's 43%. Impact Scoring also leads on update cadence (every 8 days vs every 35 months) and rating (4.9 vs 4.6). XFR's advantage is ratings volume (824 vs 18) and iOS requirement (11.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
