# NFM vs VOLBotClient

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 (34 vs 4). On ads, in-app purchases and device support there is nothing between them.

VOLBotClient is free to download; NFM costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

NFM holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: NFM has 34 ratings behind it against 4, so its average is the more settled of the two.

NFM ships an update every 12 months, VOLBotClient fortnightly. Both last shipped on October 24, 2026.
