Your Apple Watch
is enough
You don’t need a second running watch. Your coach reads the data already on your wrist, picks today’s workout, and talks you through the run.
Recording is free. The coach is a subscription; all three prices are in the table below. Runvis opens on the Korean App Store first, and other regions follow.
You don’t need to buy
a second running watch
People say you need a dedicated running watch — a Garmin Forerunner, a Coros — to see metrics like training load and recovery time. But the sensors those numbers come from are already in the Apple Watch.
The sensors are already on your wrist
Heart rate, GPS, cadence, altitude. Recent watches also measure ground contact time and vertical oscillation.
The formulas are public
Training load, recovery time, and threshold estimates come from published sports science formulas. Runvis runs those formulas on your device.
What was missing was the coach
Someone to read the numbers, pick today’s workout, and talk to you while you run. That is the part Runvis does.
There is no extra device to buy. The Apple Watch already on your wrist is the hardware. The only cost is the coach: ₩1,900 a month, ₩15,000 a year, or ₩39,000 once for the lifetime pass, at Korean App Store prices. You need one watch per person; the lifetime pass is a single ₩39,000 payment and covers an Apple Family Sharing group. What a dedicated watch does differently is written out metric by metric.
You don’t need a watch yet. The iPhone alone records GPS and calls your split pace every kilometre — every mile if that is your unit setting — and without a subscription that split is the only thing it says. Form coaching needs the wrist sensors, so it stays on the watch.
Open it in the morning
and today’s workout is set
It compares last night’s sleep, HRV, resting heart rate, and yesterday’s training load against your own 28-day baseline. Then it picks today’s workout and adds one line on why.
You can hear it without waking the watch — say “Hey Siri, What should I run today with Runvis” and today’s call is read back to you. Readiness and this week’s plan answer the same way.
The decision first, the reasons below it
Today’s workout sits at the top. The reasoning behind it sits right under. The rest of the metrics move down as reference. Tap a metric to see what it means, how it is calculated, and your usual range.
These three cells are example values that show how the screen is laid out. The capture beside them is the real app.
- On an off day it lowers the intensity and tells you why
- If you don’t like the easier version, you can keep the original workout
- When there isn’t enough data, it shows “Learning” instead of a number
All eleven screenshots on this page — five iPhone, six Apple Watch — were captured with the app running in your language. The mid-run screens come from a real recorded run. The app keeps being fixed after a capture is taken, so the build you install can be newer than what you see here.
Only what you need,
right when you need it
Everything the coach says starts from something the sensors picked up. Tap to hear the real guidance.
Say “Hey Siri, Start a run with Runvis” and the start screen opens straight away. The spoken phrases exist in all six languages.
Up to 8 cues per 30 minutes on an easy run, 6 on a tempo or a race, and never two inside 45 seconds. Splits sit outside both rules and always come; hill warnings sit outside the 30-minute budget but still wait 45 seconds after the last cue. On intervals the switches you left on set the frequency instead of a ceiling.
You press start onceFree
The screen, the timer and the auto start are free. The coach walking you through it by voice is the subscription.
Weather briefing
“It’s 26 degrees Celsius with 78 percent humidity. Hot and humid — evaporation is working against you.”
Live weather for the neighborhood you’re in right now.
Warm-up
“Hip circles, 20 seconds. Now the other way. Three, two, one.”
A timer leads you through each stage, and the coach talks you through them when it is on.
Just run
“You’ve started running. Recording now.”
It senses the running rhythm at your wrist and starts recording.
When you finish,
you see the why behind the numbers
Splits, heart rate zones, running dynamics, and a one-line coaching note are free. Subscribe and you also get the PR book that finds your fastest stretch inside a run, a lactate threshold estimate, and this week’s distance budget.
Workout detail reportFree
Pace by segment, heart rate zone distribution, average cadence and ground contact time. Plus one line of coaching on this run.
Body reportFree
Readiness, sleep, HRV, resting heart rate, VO₂max. Tap one to open the chart and your 28-day baseline range.
Coach records radar (fastest segments · PR book)Subscription
It finds the fastest 1K, 5K, 10K and half segments inside your runs over the last 90 days, even when the run was a different distance. It also shows the gap to your previous best.
Lactate threshold estimateSubscription
It estimates threshold pace and heart rate from two or more best 30-minute stretches in your last 90 days of running. Once a maximum heart rate is set, only stretches held above 85% of it qualify.
What if there is no 30-minute stretch?
With no 30-minute stretch it falls back to a 20-minute one. Failing that, it estimates from the whole-run average of three runs of 20 minutes or more held above 85% of your maximum heart rate, and that last path only works with a maximum heart rate set. It always writes on screen which of the three it used.
Coach brakeSubscription
It looks at your last four weeks of training and tells you how much distance is okay this week. If you say something hurts, it lowers that number.
Runvis VDOTSubscription
It works VDOT back from your best efforts and predicts your times at each distance. You see it side by side with Apple Watch VO₂max.
When a number is an estimate, we call it an estimate. When there is not enough to go on we show “learning” instead of a number. Anything we cannot stand behind is not in the app.
Tap a metric and see it against your usual range
It shows whether today’s value sits inside your 28-day range, and where it lands next to four weeks ago. You don’t need to know the terms. Every metric comes with what it means and how it was calculated.
- Training load, ACWR, and recovery time are calculated with published formulas
- Export an AI analysis report from the workout detail and paste it into whichever AI you use
- GPX export and a 3D flyover video of your route
A week-by-week plan up to race day,
a segment strategy on the day
Enter your goal race and target time and it builds a week-by-week roadmap. It also tells you honestly whether that target fits your current fitness. Viewing the plan is free. Having the coach run you through each segment on the watch is part of the subscription.
Pick a coach and the plan and the tone change with it
Finish first, balanced, or chasing a time. Pick one of the three and both the training mix and the tone during the run change together. If you’re new, no coach will hand you intervals that are too much.
- The coach drives each interval segment, then scores the session against the plan
- On an off day, one tap lowers the intensity and rebuilds the plan
- With no race times on file, one 12-minute test run on the watch builds your first plan
A coach who knows the race course in advance
Load the race GPX and it knows where the climbs come before you do. Send grade-aware segment paces and fueling points to the watch, and on race day you just follow the guidance.
- One recent result gives you predicted times and target paces for the 5K, 10K, half, and full
- Run the same course again and your best becomes a ghost that tells you the gap
- From 15 days out, a predicted time that factors in the race-day forecast

The coach still talks in a tunnel.
Recording and analysis all happen on the watch and the iPhone. Weather look-ups send coordinates rounded to about a kilometre; the neighbourhood name and auto-generated routes send your current coordinates to Apple services, only at that moment. Beyond those there are App Store payments, the download of the public course and shoe list files, and — on the Korean App Store only, for now — an external running-shoe search page that opens when you tap it yourself on the shoe screen. Every one of those exceptions is written out in the privacy policy. Your workout and health data are never uploaded. Privacy Policy
Recording is free —
you only pay for the coach
Recording, viewing plans, and reports are free. The coach speaking to you and the deeper analysis are the subscription. Runvis launches on the Korean App Store first, where the coach is ₩1,900 a month; in every other region your own App Store’s price applies, and the exact figure for your store goes on this page the day it is set. Accounts the App Store judges eligible get 1 month free — the same 1 month whether they pick monthly or yearly.
- GPS tracking, pace, heart rate, laps, saved to Apple Health
- Workout detail report, body report, run history
- Plan viewing, basic race predictions, the weather briefing and warm-up screen, race mode on the watch with your personal-best ghost
- Running with the watch: voice for splits (in your unit setting), heart-rate zones, pace, climb warnings and off-route alerts
- Running with the iPhone alone, splits are the only free voice

| MonthlyRenews monthly · cancel any time | ₩1,900 |
|---|---|
| YearlyAbout ₩1,250 a month · roughly 34% less than monthly | ₩15,000 |
| LifetimeOne purchase · no auto-renewal · Apple Family Sharing | ₩39,000 |
That is the Korean App Store price — Korea is the launch store. Anywhere else you are charged your own App Store’s local price.
If you are reading this outside Korea, take these as size only: ₩1,900 a month is about US$1.40, ₩15,000 a year about US$11, and the ₩39,000 lifetime pass about US$28. That is a size, not a bill.
Prices in other regions, the real saving, the break-even sum
Those conversions are there to give the amounts a size; they are not what you would be charged. Apple charges by price point, and each country’s price points are set separately, so the real figure sits at a round local price above or below them. The real numbers go on this page as each store is set up. The app’s purchase screen never guesses — it prints the price the store hands it.
Yearly is ₩15,000 — about ₩1,250 a month, roughly 34% less than paying monthly on the Korean App Store. Other stores price in their own tiers, so that ratio can come out differently; the app’s purchase screen works the real saving out from the two prices it is offered. On an eligible account the yearly plan comes with a free period too, but it is 1 month long — the same as monthly, not a year. When that month ends, the whole ₩15,000 year is charged at once.
Instead of subscribing, a lifetime pass for ₩39,000 — a launch price. If it rises later, the rise never reaches anyone who already bought. At Korean App Store prices that works out to roughly 2.6 years of the yearly plan, or about 20 months of the monthly one; your own store’s price points can land on a different ratio. It is the only plan Apple Family Sharing covers.

- Coach's Record Radar — records start being caught from a single run of 1 km or more.
Runvis launches on the Korean App Store first; other regions will follow over time. The launch date is set after the TestFlight beta ends, and it will be written on this page first. You can cancel in your App Store account settings at any time. Cancelling keeps access until the period ends and stops the renewal. Refunds follow Apple’s refund policy.
What people ask first
Do I need a watch?
The iPhone alone records GPS and calls your split pace every kilometre — every mile if that is your unit setting. Without a subscription that split is the only thing the phone says. With a subscription the phone also coaches your pace; the heart-rate zone calls need a heart rate, and an iPhone has no heart-rate sensor, so they arrive only when a Bluetooth chest strap (a standard BLE heart-rate band such as a Polar H10 or Wahoo TICKR) is connected. Form coaching, hill warnings and off-route alerts exist only on a watch run.
Which Apple Watch do I need?
watchOS 10 or later (Apple Watch Series 4 and up) and iOS 17 or later. Past that line, heart rate and GPS are all it needs. On newer models that measure ground contact time and vertical oscillation the form coaching is finer; on the others it works from cadence.
What happens to my data if I cancel?
Your runs stay in Apple Health, untouched. After cancelling you keep recording, plan viewing and the workout detail report for free.
Where does my data go?
There is no account and no server. Location leaves only for weather, the neighbourhood name and auto-generated routes. Beyond that there are App Store payments, the download of the public course and shoe list files, and — on the Korean App Store only, for now — an external shoe-search page that opens when you tap it yourself on the shoes screen. Workout and health data are never uploaded.
How complete are the six languages?
Every line the iPhone coach speaks is pinned by a test in all six languages — a 45-minute run is replayed second by second on each build to check that every cue it produces is translated. The watch’s live coaching loop sits outside that test bundle, so a line can still be missing from the tables; when one is, you hear English, never Korean, and that fallback is pinned by a test as well. The text drawn on the app’s screens uses a different table from the coach’s voice.
What do the tests actually hold?
The four translation tables must agree key for key and placeholder for placeholder, and every line written in a table must be reachable through the lookup the app actually uses. The iPhone coach’s 45-minute replay runs in six languages × metric and imperial, and one mismatch fails on the spot. Cues with numbers in them are spoken in each language’s own word order too (splits, hill warnings, pace, heart-rate zone and training steps included).
Can I start with no history at all?
Yes. One 12-minute test run on the watch produces an estimated 5K and 10K time and your first plan the same day — that test is watch-only. With the iPhone alone you still get GPS recording, split pace cues and the training plan from day one, and the plan starts from your recent weekly distance instead. Readiness needs nights slept with the watch before its baseline exists, so it usually appears around two weeks in, and ACWR around four. Performance condition appears once you have set a maximum heart rate and logged three runs longer than ten minutes, with heart rate, in the same intensity band (easy, moderate or hard). For the first few the comparison runs against a baseline not yet separated by intensity or by the point of the run it was read at, and the app writes that on the screen itself.
Who gets the free trial?
Only accounts the App Store still counts as eligible for this subscription’s introductory offer. If you have subscribed before or already used the trial, you are charged from the first payment. The app’s purchase screen always tells you which case you are in before you buy. As configured today the free period is 1 month on the monthly plan and 1 month on the yearly one; picking yearly does not make a year free. The length itself is sent down by the App Store with the product, so the app shows you exactly what it received, right before the purchase. On yearly, the whole year is charged once that 1 month ends.
Lifetime or yearly — which is better?
The lifetime pass is a one-time purchase with no auto-renewal. By the maths on the price card it breaks even at about 2.6 years against yearly, or about 20 months against monthly, so if you expect to use Runvis longer than that, lifetime is the cheaper side. It is also the only plan Apple Family Sharing covers — the monthly and yearly subscriptions are not eligible.
What happens when I change device?
The runs themselves live in Apple Health, so the Health app on the new device brings them across. What lived only inside Runvis — your profile, heart-rate zones, shoe list and the baselines the coach built — goes out as a single file from Settings → Data → ‘Export my data’, and comes back on the new device with ‘Import from backup’. The file stays only where you put it; Runvis sends it nowhere. The subscription comes back through the App Store’s restore purchases.
Is there a watch face complication or a widget?
Not yet. Watch face complications, an iPhone home screen widget and Live Activities are not in this build. They are planned, but there is no date.
Try it first in the beta
What can be checked right here, today
- 766 automated tests check the coach’s spoken lines, the free/paid boundary and the plan maths on every build.
- 2,341 interface strings line up key for key across all six language tables, and the four coach-voice tables hold 396 lines each. One mismatch and the test fails on the spot.
- 41 metric explanations ship inside the app — tap a number you do not know and you get its meaning, how it was calculated and your own usual range.
One person builds this app. There are no ratings and no press yet — it has not shipped. So instead of numbers that could be invented, these are counted straight out of the app’s repository. Anything else you want to know, write to help@runvis.app; the reply comes from me.
Leave an email address and you get one invitation when the TestFlight beta opens. The day the opening date is set, it goes here and to every address already on the list.
There is no opening date yet. The day there is one, this paragraph becomes that date — if you see no date here, it has not been set. Until then there are two things you can do: take your place in the queue (the beta build has every coach feature switched on, free, for as long as the beta runs), or run the 5K demo right now and hear when and how the coach talks.
Run the 5K demoWhat you can look at right now
- The 5K demo — hear exactly when the coach speaks and when it stays quiet, and where the free cues end and the subscription ones begin.
- The heart-rate zone calculator — your five zones, worked out here with the same Karvonen formula the coach’s voice uses. Your age and resting heart rate are all it needs.
- Thirteen Seoul course GPX files — download them now, with no install, and load them into the watch or map app you already use.
- What signing up leads to — the four steps: sign-up, TestFlight invitation, feedback, launch. In the beta build every coach feature is free for the length of the beta.
- The privacy policy — what this form collects, and how far anything the app holds ever leaves the device. Both written down.
