Miles

Overview

Miles is an AI running coach for iPhone, built around goals from a first 5K to a marathon. It suits runners who want a plan that adjusts to missed sessions and coaching cues during a run. Its free tier is useful for tracking and trying out a goal, while the training guidance that sets Miles apart requires Pro.

Key features

Training that can move with your schedule

Miles Pro builds a week-by-week plan around current fitness and reshapes it when runs are missed. That flexibility is valuable for new runners and those returning after a break, whose schedules or training capacity may change. Personal-best chasers and marathon trainees also get plans aimed at their chosen distance: 5K, 10K, half marathon or marathon. The free plan offers a preview, so runners cannot rely on it for an ongoing adaptive program.

Pace cues and post-run feedback

During a run, Pro tracks GPS pace and gives audio cues when you drift off target. Intervals, tempo runs and long runs make the schedule more purposeful than a sequence of ordinary mileage sessions. After each run, Miles analyzes what worked and what to change, giving the next workout some context. The combination is most useful to runners who want direction while moving and a review afterward; someone who only needs a place to record runs may find the free tracking sufficient.

Indoor sessions and health connections

Miles counts treadmill runs and provides structured workouts and post-run analysis for them, which helps indoor sessions remain part of training. Pro also connects with Apple Health and Bluetooth heart-rate monitors, and includes readiness and training-load features. These tools broaden the coaching picture, though they are all part of the paid plan.

Location and health data

Miles collects location and fitness information such as GPS data, distance, pace, cadence, heart rate and workout time. With consent, anonymised pace and distance data may be shared with an AI partner to produce coaching insights and recommendations. The company says it encrypts data in transit, limits personal-data access to people who need it and uses industry-standard encryption technologies with its cloud providers. Users can request access, correction, erasure, restriction, portability or objection to processing, and can withdraw consent. Support is available at [email protected].

Pricing

The Free plan costs nothing and includes iPhone run tracking, goal setting and a plan preview. It is a reasonable starting point for runners who want to log sessions or inspect a goal plan, but it leaves out adaptive training, live coaching, post-run analysis, readiness and training load, and the health-device connections.

Miles Pro Monthly costs $14.99 a month, billed immediately through the App Store, with no free trial. It includes the adaptive plan, live audio pace coaching, post-run analysis, readiness and training load, Apple Health and Bluetooth heart-rate monitor support. Monthly billing suits someone who wants the full feature set without committing for a year, at a higher cost over time.

Miles Pro Annual costs $99.99 a year, billed through the App Store after a 7-day free trial. Its features match Monthly, and its listed equivalent is 8.33 /mo. This is the lower-cost choice for runners prepared to commit for a year; remember that billing begins after the trial. A one-time Miles Pro offer is $69.99, paid once, but its feature terms are not defined. The general pricing note says paid plans start at $8.33/mo (annual) and offers a 7-day trial; the plan terms specify that the trial applies to Annual, not Monthly.

Platforms

Miles is available on iOS. The App Store lists compatibility with iPhone running iOS 18.5 or later and Apple Watch running watchOS 11 or later. Android and web users will need another option.

Who it's for

Miles is best suited to new runners, comeback runners, personal-best chasers and marathon trainees who want structured running guidance, especially if they train both outdoors and on a treadmill. It is less compelling for runners who only need basic logging, want coaching without a subscription, or use Android.

Pros and cons

• Plans adapt when runs are missed: the week-by-week Pro schedule can respond to interruptions instead of leaving a runner with a stale calendar.
• Coaching spans the session: GPS pace cues, structured workouts and post-run analysis cover preparation, execution and review.
• Treadmill training counts: indoor runs can receive structured workouts and analysis, keeping them within the training routine.
• The free tier stops short of coaching: it provides tracking, goals and a preview, while the features that distinguish Miles sit behind Pro.
• Platform reach is narrow: the app is iOS-only and requires recent iPhone and Apple Watch software.
• Health and location data are central to the service: runners should be comfortable sharing these categories of data, and consider the optional AI-partner sharing consent.

Alternatives

For a broader list of AI fitness apps, compare coaching tools across categories. Choose Freeletics if you want free workouts, exercises, runs and audio sessions across Android, iOS and web, and can accept a limited content selection. APEX is another freemium option, with uncapped workout and meal logging and unlimited custom routines in its free plan; its focus may suit people seeking logging and routine building alongside training.

ARDOR is an iOS alternative with one free workout a week and full access for its first 7 days. Kemtai is worth considering if you need support across Android, iOS, web, Windows or an API. Saga Coach offers three workouts free and a chat trial, with a $12.99 monthly plan for unlimited workouts and full chat access. Styrki keeps GPS runs, cardio and heart rate in its free plan, alongside manual logging and personal-best tracking. Yogini is an iOS and macOS option with yearly and monthly plans. AI-Training is a paid option for Android and iOS users.

Verdict

Choose Miles if you run on iPhone and want one service to shape a flexible plan, keep you near target pace and review each session, including treadmill workouts. Its strongest reason to choose is that connected coaching across the training cycle; its clearest reason to look elsewhere is the subscription required for that coaching, compounded by its iOS-only reach. If tracking and goal setting are enough, the free plan covers those basics; if you need adaptive guidance, budget for Pro.
