# DashCommand vs RaceChrono Pro

The clearest difference is price: DashCommand at $9.99 against RaceChrono Pro's $19.99. DashCommand also leads on ratings volume (2.1K vs 174) and iOS requirement (9.0 vs 15.6). RaceChrono Pro's advantage is rating (4.7 vs 4.2) and update cadence (monthly vs every 3 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

DashCommand costs $9.99 and RaceChrono Pro $19.99 up front. DashCommand sells 14 one-off in-app purchases and RaceChrono Pro sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

RaceChrono Pro holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: DashCommand has 2.1K ratings behind it against 174, 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 57% of RaceChrono Pro's.

DashCommand ships an update every 3 months, RaceChrono Pro monthly. Both last shipped on September 25, 2026.
