Verdict

The call

The clearest difference is ads: VoltBook at none against Network Toolbox Net security's shown. VoltBook also leads on update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.6). Network Toolbox Net security's advantage is ratings volume (3.4K vs 1) and iOS requirement (13.0 vs 15.1).
