Verdict
The clearest difference is rating: XProtect® Mobile at 2.2 against Voltage Mail's 1.7. XProtect® Mobile also leads on monetization model (free vs freemium) and review sentiment (25% vs 8%). Voltage Mail's advantage is ratings volume (736 vs 126) and iOS requirement (15.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.
