Verdict

The call

The clearest difference is in-app purchases: XFR at none against Eagle Ballistics's 6. XFR also leads on ratings volume (824 vs 30) and iOS requirement (11.0 vs 17.0). Eagle Ballistics's advantage is review sentiment (75% vs 43%) and update cadence (monthly vs every 35 months). On price, ads and device support there is nothing between them.
