Verdict
The clearest difference is price: VOLBotClient at Free against NFM's $4.99. VOLBotClient also leads on update cadence (fortnightly vs every 12 months) and iOS requirement (9.3 vs 14.0). NFM's advantage is rating (4.9 vs 4.3) and ratings volume (33 vs 4). On ads, in-app purchases and device support there is nothing between them.
