If you searched "Edge Apple Watch app", you are probably one of two people. Either you already use Edge on your phone and you want to know what the Watch app actually does. Or you are weighing Edge up against other training apps and the Watch experience is going to decide it for you. Good news. This guide is for both of you.
Edge is a UK training app for runners and gym goers, built around a real human coach who writes your plan, with AI to keep that plan moving as your week shifts. There are over 17,000 of us using it. And yes, there is a proper Apple Watch app. Not a half-baked sync tool. A real, native training app that runs your session from the wrist.
Below is the full breakdown. What the Watch app is, what you can do on it, what stays on the phone, how to set it up, which Watch models work, and how Edge AI fits into the picture.
1. What the Edge Apple Watch app actually is
The Edge Apple Watch app is a native watchOS app. That matters. A lot of training apps on the App Store are really just phone apps with a sync widget that ships your finished workout back to HealthKit. Edge is different. The Watch app runs the workout itself, on the wrist, in the same way that the built-in Workout app does.
When you launch the Edge app on your Apple Watch, you see your session for today. The one your coach wrote. Tap it, tap start, and the Watch handles the rest. Heart rate, pace, distance, cadence, interval timing, all live on the watch face. Voice prompts ping in your ear at the moments that matter. Start of the interval. End of the interval. Halfway through a hard rep. The big stuff.
The reason this is worth understanding upfront is that it changes how you train. You stop thinking about your phone mid-session. The Watch is the training tool. The phone is the place where your coach lives, where you chat, and where you review what you just did. Two devices, two jobs.
2. What you can do from the wrist
Here is the actual list of things you can do on the Edge Apple Watch app without touching your phone.
- See today's session. Your coach-written workout is right there on the home screen of the Watch app. Title, structure, expected duration.
- Start the workout. One tap. The Watch takes over from there.
- Follow intervals live. Each block shows you the target pace, the time or distance to cover, and a live countdown. Heart rate sits next to it.
- Hear lean voice prompts. Edge gives you the markers that actually help. Start of interval, end of interval, pace warnings, key milestones. Not chatter.
- Pause and resume. Stop for a traffic light, a bathroom, a coffee, whatever. Pick back up where you left off.
- Complete and log. Tap finish and the session syncs back to the Edge app on your phone. No copy paste, no fiddling.
- See your strength sets. If today is a gym day, the Watch shows you the movement, the sets, the reps, and the rest timer between sets.
That covers maybe 95 per cent of what you actually do during a training session. The other 5 per cent, which is reviewing the plan in detail, chatting to your coach, swapping sessions around, lives on the phone, which is exactly where you want it.
3. What stays on the phone
The phone is where the thinking happens. The Watch is where the doing happens. Here is what lives on your iPhone in the Edge app, not on the Watch.
- The full plan view. Your whole training week, your whole month, your build toward whatever event you are targeting.
- Full progress charts. Heart rate trends, pace trends, training load over time, weekly mileage, strength PRs.
- Edge AI chat. Ask Edge AI a question and get a 30-second answer. Tired today and want to swap a hard run for a steady one? It can do that.
- Speak to your coach. Real humans, real chat thread. Send a voice note about how the run went, get a reply back.
- Video demos. For strength and mobility work, your phone shows you general coach video demos for every movement, so you know what good form looks like before you head to the gym.
- Flexi Swap. Swap a session for a different one if life got in the way. You do this on the phone, and the Watch picks up the new session the next time you open it.
If you have ever used an app that tried to cram everything onto the Watch, you know why this split is the right one. You do not want to scroll through training history on a 45mm screen. You want to start the workout and run.
4. How the whole workflow works, end to end
From the first time you open Edge to the moment you finish your first session on the Watch, the journey looks like this.
- Sign up. Free 7-day trial. You install the Edge app on your iPhone from the App Store.
- Onboarding. Edge asks you a few questions. Your training history, what you are training for, when you can train, any niggles or injuries, what equipment you have.
- A human coach writes your plan. Within 24 hours, a real Edge coach has built you a starting plan. Not a template. A plan that fits the answers you gave.
- You install the Apple Watch app. From your iPhone, tell Edge to install the Watch companion. Two minutes.
- Today's session is on your wrist. Open the Watch app, today's workout is sitting there waiting. Tap start.
- Train. The Watch coaches you through. Voice prompts. Heart rate. Pace. Intervals. The lot.
- It syncs back. Finish the session and it flows back to your Edge app on the phone. Your coach can see it. Edge AI can see it. The next session adjusts accordingly.
The thing to notice in that flow is that Edge AI handles the ongoing adjustments to the plan after that first coach build. Have a bad week of sleep? Skip two sessions? The AI sees what is happening and helps shape what comes next. Your human coach is still in the loop on the phone for the big stuff. But the Watch keeps quietly doing its job.
5. How to set up the Edge Apple Watch app in 3 steps
Setup is the easy bit. You will be done in two minutes.
Step 1. Install Edge on your iPhone. Search Edge on the App Store. Download. Open. Sign up for the free trial if you have not already.
Step 2. Connect your Apple Watch. In the Edge iPhone app, go to Settings, then Connect Apple Watch. Edge will trigger an install of the companion Watch app. If you have the standard "auto install apps on Apple Watch" turned on, this happens automatically the moment you install Edge on the phone. Otherwise, open the Watch app on your iPhone, scroll to "Available Apps", find Edge, tap Install.
Step 3. Open Edge on the Watch. Press the digital crown. Scroll to Edge. Tap. The first time you open it, the Watch app links itself to your Edge account on the phone. After that, today's session is one tap away every morning.
That is it. Three steps. Two minutes. One tap away from training.
6. Which Apple Watch models work with Edge
Edge runs on every Apple Watch that supports watchOS 10 or later. In practice that means:
- Apple Watch Series 6, 7, 8, 9, and 10. All fully supported.
- Apple Watch SE 2nd generation. Fully supported.
- Apple Watch Ultra and Ultra 2. Fully supported. The bigger screen and longer battery make these a particularly good pairing for long runs.
If you are on an older Series 4 or 5, Edge may run depending on which watchOS you can update to, but the experience will be more limited. For the best experience we recommend Series 6 or newer on watchOS 10 or 11.
7. What runs and strength sessions look like on the Watch
Two different sport modes, two different screens. Here is what you see.
On a run. The main screen shows current pace, target pace for the current interval, heart rate, distance covered, and a live countdown on the current interval. If you are in a fartlek or interval session, the Watch tells you when each rep starts and ends. If you are in a steady run, it watches your pace and pings you if you drift outside the target range. Cadence is tracked in the background and shows up later on your phone.
On a strength or mobility session. The Watch shows you the current movement, the set you are on, the reps to hit, and a rest timer for between sets. Tap the watch when you finish a set and the rest timer kicks off. When rest is up, the Watch buzzes your wrist and shows the next set. For form, the phone is the place to go before the session, where you watch the general coach video demos.
HIIT-style training sits in between these. Edge handles HIIT training (which has two I's, by the way) the same way it handles intervals on a run. Each block is timed, each rest is timed, the Watch buzzes at the transitions.
8. Battery and data usage
A reasonable question if you are about to start using the Watch for an hour-long run.
Battery. A typical Edge session burns about 7 to 12 per cent of your Apple Watch battery, depending on whether GPS is on, whether you are streaming music, and how much you check the screen. A one-hour run on a Series 9 with GPS on will land toward the middle of that range. An Ultra 2 will use noticeably less.
Data. The Watch downloads your session over your iPhone, before you head out, so 4G or LTE on the Watch itself is optional. Once a session is loaded, the Watch can run it in airplane mode if you want, and it will sync back to the phone next time it connects.
Music. If you stream from Apple Music, Spotify, or anything else, that is the bigger battery cost, not Edge. The Edge voice prompts duck the audio briefly when they ping in, the way a sat-nav does.
9. Why this matters specifically if you wear an Apple Watch
If you wear an Apple Watch already, your training app needs to live there. That sounds obvious but a lot of apps still treat the Watch as an afterthought. They want you to bring your phone on every run. They want you to tap through the workout on a 6-inch screen. They want the Watch for one job only, which is to track your heart rate.
Edge does it the other way around. The Watch is the primary training device during a session. The phone is the planning and review device. That is the right split for Apple Watch users specifically, and especially for runners who do not want to lug a phone on a long Sunday morning out.
The other thing that matters for Apple Watch users is HealthKit. Edge writes your finished sessions back to Apple Health, so your Activity rings, your weekly Move totals, and any other apps you use that read from HealthKit (Strava, AutoSleep, sleep apps, recovery apps) all see your training. You are not building a parallel data silo. Your Edge sessions are part of your wider Apple Health picture.
10. How Edge AI fits in
The relationship between the human coach, Edge AI, and the Watch app is the bit that confuses people. So here it is in one paragraph.
Your human coach writes the starting plan, within 24 hours of signing up. After that, Edge AI handles the ongoing adjustments. If you miss sessions, Edge AI shifts things around. If you nail a steady run faster than expected, Edge AI bumps the target paces. If you tell it you are tired today, Edge AI can swap a hard session for an easier one. You can chat to Edge AI from your phone, get answers in about 30 seconds, and ask things like "swap today's intervals for a steady run" or "why is this week harder than last week?". The Watch app simply shows you whatever the current plan says, after both the human coach and Edge AI have done their thing. You do not have to think about the difference. You just open the Watch app and train.
You can also speak to your coach directly, in the chat thread on the phone, for anything that needs a human. Niggles, race-day questions, big changes to the plan, race week strategy. Real humans, real conversations.

You can see today's session on the Watch, ready to start. The full plan view (the whole week, the whole month, the build toward your event) lives on the iPhone app, where it is much easier to read and review.
How long does Edge battery use last?
A typical Edge session uses about 7 to 12 per cent of your Apple Watch battery, depending on GPS, music streaming, and screen interaction. A Series 9 with GPS on for an hour-long run lands around the middle. An Ultra 2 uses noticeably less.
Does Edge track HR on Apple Watch?
Yes. Edge tracks heart rate live during every session using the Apple Watch sensor, alongside pace, distance, and cadence. The full session data syncs back to the Edge app on your phone and is also written to Apple Health.
