1RunZone
RunZone is built specifically around Zone 2. It calculates your zones, builds a weekly plan for your goal (5K to marathon, weight loss or general fitness), and talks you through runs with voice cues for pace, heart rate and drifting out of zone while the app is open. Its main progress chart shows your pace getting faster at the same heart rate. It also includes a fitness-based Run Age, AI form check from a short video, an AI coach and a meal scanner.
Good to know: iPhone only. It reads heart rate from Apple Watch through Apple Health, or coaches by pace without a watch. It requires a subscription, with no free tier.
2Runna
Runna offers structured plans from a first 5K to ultramarathons, with strength sessions and pace adjustments. Strava owns it, and there's a Strava + Runna bundle. The free version covers week 1 of a plan; the rest needs Premium. It's a strong pick if your main goal is a race time.
3Garmin Coach
If you already own a compatible Garmin watch, Garmin Coach gives you adaptive training plans for 5K, 10K and half marathon at no extra cost. It needs Garmin hardware and Garmin Connect.
4Nike Run Club
Nike Run Club is free and best known for its audio-guided runs, which many runners love. Its training plans are mostly fixed rather than adaptive, and it isn't built around heart rate zones.
5Strava
Strava is the go-to app for tracking runs and the social feed. The free version handles tracking and community; many training and analysis features are paid. It analyzes your heart rate but doesn't build a Zone 2 plan for you, so many runners pair it with a coaching app.
