Verdict
The clearest difference is rating: Half Marathon 13.1 Trainer at 4.7 against Run Half Marathon's 4.2. Half Marathon 13.1 Trainer also leads on update cadence (every 6 weeks vs every 12 months) and ratings volume (5.6K vs 119). Run Half Marathon's advantage is review sentiment (71% vs 56%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Half Marathon 13.1 Trainer sells 5 in-app purchases, starting at $4.99 per month and Run Half Marathon sells 6 in-app purchases, starting at $2.99 per 6 months. Whichever you choose, the download price is not the number that matters.
Half Marathon 13.1 Trainer holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Half Marathon 13.1 Trainer has 5.6K ratings behind it against 119, so its average is the more settled of the two. Written reviews complicate that: 56% of Half Marathon 13.1 Trainer's written reviews are positive against 71% of Run Half Marathon's, so the app with the better star average is not the one people write more warmly about.
Half Marathon 13.1 Trainer ships an update every 6 weeks, Run Half Marathon every 12 months. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
