Why it hits different

Indoor training that
doesn't feel like indoor training.

Most SkiErg apps give you numbers on a screen. SkiEr gives you a mountain to ski down, a pace to chase, and a reason to finish the set.

Immersive routes

Ski real terrain, not a loading bar.

Seven procedurally-generated routes across pine forests, frozen lakes, sunset peaks, and moonlit ridges. Each with its own weather, light, and medal targets.

  • Terrain and trees respond to your pace
  • Bronze / silver / gold medal targets per route
  • Day, sunset, night, and blizzard environments

Ghost PB racing

Race the best version of yourself.

A translucent skier representing your personal best glides alongside you. See exactly where you're ahead, where you're behind, and where to push.

  • Auto-loads your PB for the selected route or distance
  • Real-time lead / trailing indicators
  • Celebratory haptic when you overtake your PB

Gear Room

Your skier. Your colours.

Customise your avatar's suit, skis, and poles across ten colour options each. Small detail, but it's your avatar on that mountain.

  • Male and female avatars
  • Suit, ski, and pole colour presets
  • Day / sunset / night / blizzard environments

Seven routes

From a warm-up jog to a half-marathon epic.

Every route has its own rhythm, visual environment, and medal target. Ski the same route twice, you'll see the terrain differently.

5 weeks · 4 workouts/week

Chase your 2K personal best with targeted threshold work, tempo intervals, and time trials.

HIIT Sprint Series

6-Week Endurance

Questions

Things people ask.

Do I need a Concept2 PM5 monitor?

Yes. The app connects to the PM5 via Bluetooth using both the FTMS standard and Concept2's own protocol. If you have a SkiErg with a PM5 (the standard package), you're set. The older PM3/PM4 monitors aren't supported because they don't have Bluetooth.

Is there a subscription?

No. It's £9.99 one time. You own the app, you get lifetime updates, and all your data stays on your device. We'll add a separate optional SkiEr Pro tier later with power-user features — but the core app will always be a one-time purchase.

Does it work without internet?

Yes. Once installed, everything runs offline — the 3D scene, routes, training plans, metrics, history. Internet is only needed to sync to Apple Health, Strava, or Game Center, and only if you use those features.

Which iPhones are supported?

Any iPhone running iOS 17 or later. That means iPhone XS / XR and newer. For the 3D scene to look best, iPhone 12 or newer is recommended, but it runs fine on older devices.

Does the Apple Watch app work without my phone?

The Watch app needs your iPhone nearby because that's where the PM5 connects. The Watch shows live metrics, interval phase, and PB pace on your wrist while your phone handles the Bluetooth connection and 3D scene.

Can I import my existing workout history from ErgData?

Not yet. v1.0 starts fresh from the moment you install. We're looking at ErgData CSV import for a future update if enough people want it.

Is my data private?

All your workout data is stored locally on your device in Apple's standard SwiftData store. Nothing is uploaded anywhere unless you explicitly connect Strava (which uploads individual workouts you complete) or enable Apple Health sync (which stays within Apple's ecosystem). We don't have servers. We don't have an account system. There's nothing to hack.

What's next

We're not done.

Lifetime updates means we keep shipping. Here's what we're actively working on — no dates, no promises, just honest direction.

Richer character & gear detail

Tighter animation on the 3D skier, better pole and ski rendering, and more avatar customisation options.

More routes & environments

New terrain types, new weather, new times of day. We're building a library of places to ski, not a fixed map.

More training plans

More goal-specific plans based on what athletes actually train for — Hyrox, 500m sprint, ultra-distance.

ErgData history import

Bring your existing PM5 workout history in from Concept2's ErgData app so nothing starts from zero.

We ship what we're sure of, and we tell you about what we're not. Email us what you'd add.

Go ski.

Pull up a route, hit start, and let the mountain do the rest.
