RunHUD
Read full descriptionHide full description
RunHUD is a simple, no-setup running companion for treadmill workouts. Just open the app, connect a watch or strap that broadcasts heart rate over Bluetooth, and start running. While you run on a treadmill, RunHUD shows your heart rate, pace, and elapsed time clearly on your phone — just like a heads-up display (HUD). If the sensor connection drops, the numbers change to "--" so you know, and RunHUD picks up automatically when the device sends data again. On a watch, restart its broadcast feature, such as Virtual Run. No settings. No distractions. Perfect for runners who want to focus on their run without constantly checking their watch.

Verdict
The clearest difference is price: RunHUD at Free against GPX Splice's $1.99. RunHUD also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (16.2 vs 18.0). GPX Splice's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
