Verdict

The call

The clearest difference is in-app purchases: UDBapp Pro at none against GuardBox's 6. UDBapp Pro also leads on ratings volume (2.3K vs 3). GuardBox's advantage is update cadence (every 2 days vs every 6 weeks) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.
