# DashCommand vs JB4 PRO

The clearest difference is price: JB4 PRO at Free against DashCommand's $9.99. JB4 PRO also leads on in-app purchases (none vs 15) and update cadence (fortnightly vs every 3 months). DashCommand's advantage is ratings volume (2.1K vs 14) and chart position (#29 vs unranked). On review sentiment, ads and device support there is nothing between them.

JB4 PRO is free to download; DashCommand costs $9.99 up front. DashCommand sells 14 one-off in-app purchases. JB4 PRO asks for nothing beyond the download.

JB4 PRO holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: DashCommand has 2.1K ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 48% of DashCommand's written reviews are positive against 50% of JB4 PRO's.

DashCommand ships an update every 3 months, JB4 PRO fortnightly. The most recent releases landed on October 15, 2026 and October 1, 2026 respectively.
