Miles

Overview

Miles supports 5K, 10K, half-marathon and marathon goals. Pro builds a week-by-week schedule from your current fitness and reshapes it when you miss a run, so the plan is more practical for new runners, comeback runners, personal-best chasers and marathon trainees than a fixed calendar. Treadmill sessions count too, with structured workouts and post-run analysis available indoors.

The trade-off is scope: Miles is an iPhone-focused running service, not a general fitness platform. The App Store requires an iPhone on iOS 18.5 or later; Apple Watch compatibility requires watchOS 11 or later.

Key features

Adaptive training

Miles Pro turns a goal into an adaptive progression instead of leaving you to decide what to do next. Missed runs trigger a revised schedule, which can help runners maintain momentum when work, travel or recovery disrupts a week. Free users can set a goal and see a plan preview, but the full adaptive program is a Pro feature.

Live and post-run coaching

During Pro workouts, Miles follows GPS pace and gives audio cues when you drift from the target. Intervals, tempo runs and long runs provide more purposeful sessions than simply recording distance. After every run, the app supplies coach-style analysis of what worked and what to change, giving the next workout a clear point of adjustment.

Pro also includes readiness and training-load features, plus Apple Health and Bluetooth heart-rate monitor support. That makes the paid tier more useful to runners who already use heart-rate data or want workload context, rather than only pace and mileage.

Data and privacy

Miles collects location and fitness information such as distance, pace, cadence, GPS data, heart rate and workout time. With consent, anonymised pace and distance data may be shared with an AI/LLM partner to produce coaching insights and recommendations. Miles says transmission uses SSL, access to personal data is restricted, and cloud providers use industry-standard encryption. Users can request access, correction, erasure, restriction or portability, object to processing, and withdraw consent.

Pricing

The Free plan is free and includes iPhone run tracking, goal setting and a plan preview. It is suitable for runners who want basic recording or who are deciding whether Miles fits their goals, but it does not include the adaptive schedule, live pace coaching, post-run analysis, readiness and training-load tools, or the listed integrations.

Miles Pro Monthly costs 14.99 USD per month, billed immediately through the App Store. It includes the complete coaching feature set but has no free trial, making it the flexible option for short-term training at the highest ongoing rate.

Miles Pro Annual costs 99.99 USD per year, billed through the App Store after a 7-day free trial. At 8.33 /mo, it is the sensible paid choice for a season-long or year-round runner who can commit to annual billing. The Miles Pro - One time offer costs 69.99 USD per once; its listing does not describe a different feature set, so buyers should treat it as a one-off purchase option rather than assume additional benefits.

Platforms

Miles supports iOS. The stated device requirements are iPhone with iOS 18.5 or later and Apple Watch with watchOS 11 or later. Pro can connect Apple Health and Bluetooth heart-rate monitors. Android and web users need another service.

Who it's for

Choose Miles if you are progressing toward a defined running distance and want the app to determine sessions, adjust missed-workout weeks and coach pace while you run. It is particularly well matched to beginners, runners returning after a break and athletes who want a personal-best or marathon plan without building one manually. Treadmill runners also get structured indoor sessions rather than a separate, unsupported workflow.

It is a weaker fit if you need Android or web access, want broad non-running training, or object to sharing anonymised training data with an AI partner after consent. Free users should expect tracking and a preview, not the central coaching experience.

Pros and cons

• Pros: Plans cover four common race distances and adapt when runs are missed.
• Pros: Live GPS pace cues, structured sessions and post-run analysis connect preparation, execution and review.
• Pros: Treadmill workouts receive structured guidance and analysis too.
• Pros: Pro supports Apple Health and Bluetooth heart-rate monitors.
• Cons: The full coaching system requires a subscription; the free plan stops at tracking, goals and a preview.
• Cons: Monthly Pro costs 14.99 USD and has no trial; the 7-day trial is limited to annual billing.
• Cons: The service is limited to recent iPhones and Apple Watch hardware, with no Android or web platform.
• Cons: Location and health metrics are collected, and anonymised pace and distance may be shared with an AI/LLM partner with consent.

Alternatives

AI Fitness Apps is the broader starting point if you want to compare AI-led training tools rather than choose a running-specific iPhone app.

Freeletics is a better alternative when Android or web access matters; its free tier includes workouts, exercises, runs and audio sessions, although content selection is limited.

APEX suits users seeking uncapped workout and meal logging, unlimited custom routines and a larger exercise and ingredient library across Android and iOS.

ARDOR is another iOS option with one free workout per week and full access for the first seven days, followed by a 19.99 USD monthly plan.

Saga Coach fits runners or athletes who prefer chat-led support, with three free workouts and a 12.99 USD monthly plan for unlimited workouts and full chat access.

Styrki is worth considering for unlimited manual logging, personal-best tracking, GPS and heart-rate records, community features and a limited number of AI workouts.

Kemtai is an alternative paid service with Android, API, iOS, web and Windows support.

Icon Training is a paid cross-platform option for Android, iOS and web, with Premium Monthly priced at 26.99 USD per month.

AI-Training is another paid Android and iOS alternative with a free plan and free trial.

Verdict

Miles is a strong choice for an iPhone runner pursuing a specific race distance who values an adaptive schedule, in-run pace correction and feedback after every session. The annual Pro plan offers the clearest value for sustained training, while the free tier is useful only for tracking and previewing. Look elsewhere if you need Android or web support, broader fitness coverage, or the paid coaching features without a subscription.
