# Run 10k vs Half Marathon 13.1 Trainer

The clearest difference is price: Half Marathon 13.1 Trainer at Free against Run 10k's $3.99. Half Marathon 13.1 Trainer also leads on rating (4.7 vs 3.1) and ratings volume (5.6K vs 18). Run 10k's advantage is in-app purchases (none vs 5) and ads (none vs shown). On update cadence and device support there is nothing between them.

Half Marathon 13.1 Trainer is free to download; Run 10k costs $3.99 up front. Half Marathon 13.1 Trainer sells 5 in-app purchases, starting at $4.99 per month. Run 10k asks for nothing beyond the download.

Half Marathon 13.1 Trainer holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: Half Marathon 13.1 Trainer has 5.6K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 81% of Run 10k's written reviews are positive against 56% of Half Marathon 13.1 Trainer's, so the app with the better star average is not the one people write more warmly about.

Run 10k ships an update every 2 months, Half Marathon 13.1 Trainer every 6 weeks. Both last shipped on November 10, 2026.
