# RUN4 vs Tracker Pro

The clearest difference is in-app purchases: Tracker Pro at none against RUN4's 1. Tracker Pro also leads on price ($14.99 vs $17.99) and chart position (#197 vs unranked). RUN4's advantage is update cadence (daily vs weekly) and ratings volume (5 vs 1). On rating, review sentiment, ads and monetization model there is nothing between them.

RUN4 costs $17.99 and Tracker Pro $14.99 up front. RUN4 sells 1 one-off in-app purchase. Tracker Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for RUN4 against 5.0 for Tracker Pro. That said, the two scores are not equally well evidenced: RUN4 has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

RUN4 ships an update daily, Tracker Pro weekly. Both last shipped on November 13, 2026.
