Verdict
The clearest difference is rating: Half Marathon 13.1 Trainer at 4.7 against Run Joy's 1.0. Half Marathon 13.1 Trainer also leads on ratings volume (5.6K vs 2) and device support (4 vs 2). Run Joy's advantage is ads (none vs shown) and review sentiment (85% vs 56%). On price, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Half Marathon 13.1 Trainer sells 5 in-app purchases, starting at $4.99 per month and Run Joy sells 3 in-app purchases, starting at $4.99 per month. 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 1.0. That said, the two scores are not equally well evidenced: Half Marathon 13.1 Trainer has 5.6K ratings behind it against 2, 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 85% of Run Joy'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 Joy fortnightly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
