COMING FROM RUN 5K? If you’ve completed our Run 5k app and you're feeling good, you can start on Week 4 or 5 of our Run 10k app to continue your training. If you’re a couch potato, start from Week 1, or check out our Run 5k app first. AUDIO CUES and NOTIFICATIONS If you’re not getting Notifications in the background, open the Settings app, select Notifications, then scroll down to find Run 10k in the list. Tap on Run 10k and turn on Notification Center, choose an alert style, and turn everything else on (Sound, Badge App Icon, Lock Screen). Check your volume and make sure your ringer switch is not set to silent/vibrate. HEALTH This app can be integrated with the Health app. Your weight set in the Health app can be used to calculate Calories burned during a workout, and the total Active Calories burned can be saved to Health app after each workout. Sharing this information to the Health app is optional. GPS and LOCATION To show distance and pace information, Run 10k can use GPS location tracking during a workout. For best results, use this app outside where you can see open sky. Continued use of GPS running in the background can dramatically decrease battery life.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
