Ski coaching from the phone in your pocket
SkiCoach uses your phone's GPS and motion sensors while you ski. After each run you see a technique score from 0 to 100 and your turn rhythm. With PRO you also hear audio tips on what to work on next. Recording works without mobile signal and without an account.
More than 1,200 downloads. Covered by Der Grazer, Trending Topics, SnowOps Magazine, Bug.hr and 5min.at.
Free to start with 2 runs a day. Snowboard mode with ELITE or as an add-on. iPhone with iOS 16 or later, Android 8.0 or later.

What you see after a run
Tap Ski Start, put the phone in your pocket and ski. The results are waiting when you stop.
- Technique score
- A number from 0 to 100, built from two parts the app shows separately: edge control, estimated from the forces and rotation in your turns, and turn quality, how evenly you link them. Compare it with your own earlier runs on the same slope. The phone, the pocket and the snow can shift it by a few points, so watch the trend rather than a single run.
- Turns and rhythm
- How many turns you made, your rhythm in turns per minute, and how even it was. With PRO, Rhythm Coach suggests songs at the same tempo and opens them in Spotify.
- Speed, distance and altitude
- Max and average speed, distance, duration and altitude, all from GPS.
- Audio tips PRO
- Spoken through your earbuds. Choose a short summary at the end of the run, a tip after the turns that need it, or continuous coaching.
-
While you ski: live speed, distance and altitude. Swipe to pause or stop.
-
Every day on the mountain, with its score, speed and distance.
-
Totals and personal records: fastest speed, longest run, best score.
What a phone can measure, and what it can't
SkiCoach uses only the sensors already in your phone. That sets clear limits, and we would rather you know them before you buy.

Keep the phone in a front trouser pocket on your thigh, and use the same pocket on every run. A backpack, a loose jacket pocket or your hand adds movement that isn't yours. Leave the screen on. With the screen locked, the phone still records speed and distance, but not your technique.

Ski indoors, all year
Indoor Training Mode is built for ski halls, and it is included in every version, the free one too. Choose Indoor under Ski Mode in the settings or enter your hall's code, then record and compare runs the same way you do outside.
Halls with a code in the app today:
- Ski Dubai
- Snow Abu Dhabi
- SNOWworld Landgraaf
- SNOWworld Zoetermeer
- Alpincenter Bottrop
- Skihalle Neuss
- Snow Dome Bispingen
SkiCoach is an independent app. Hall names are listed so you can find yours.
Outside, the season follows the snow: December to April in the northern hemisphere, June to October in the southern.
Your runs stay on your phone
Every run is saved in a database on the phone itself. There is no SkiCoach account and no cloud copy, and recording does not need mobile signal.
GPS Run Replay is the one feature that uses the internet, to load its map background from OpenStreetMap. It shows runs recorded with Save GPS Tracks switched on in the settings.
You can export your runs as CSV, GPX or JSON at any time, and upload GPX files to Strava. Settings > Delete All Data deletes all recorded runs. Uninstalling the app removes everything.

For ski schools, clubs, hotels and indoor halls
Your students, members or guests record on their own phones, so there is no hardware to buy, charge or hand out. It works without Wi-Fi on the slope and in the hall, and the data stays on each person's phone.
We set up access together with you, through the App Store and Google Play.
Write to b2b@skicoach.app and tell us about your school, club, hotel or hall.
Who builds SkiCoach
Mihajlo Grmaš
Founder. Product and engineering.
Dipl.-Ing., based in Graz, with 18 years in software and data. Designed and built SkiCoach on his own and took it from the first prototype to a published app with more than 1,200 downloads, without marketing spend.
I can measure a turn. Bernhard knows what a good turn feels like and how to say it so that someone actually changes what they do. That was the half I was missing.
Bernhard Ratschiller
Co-founder. Snowsports and education.
Austrian state-certified ski instructor (Arlberg, 2015). Spent three years in technical leadership at Snow51 in China, where he built the training system while the company grew from 30 to more than 500 employees. Innovation award at the Beijing Winter Expo 2021. Co-founded a ski school in Hokkaido in 2023. At SkiCoach he is responsible for the coaching method and the partnerships with ski schools.
The fundamentals of skiing are movement, balance and flow. They don't change from beginner to professional. My job is to give SkiCoach the right coaching method, the right inputs and a solid technical base.
SkiCoach is a Brand Seeds Studio product from Graz, built on the Black Box Foundation, founded in 2025 and self-funded. Press material is on the press page, and background articles are in Insights.
Questions
Does it work without mobile signal?
Yes. Recording and analysis run on the phone. You need the internet only to install the app, to buy an upgrade, and for the GPS Run Replay map.
Does it work for snowboarding?
Yes, since version 2.0. Snowboard mode is included in ELITE, or available as a €9.99 add-on to PRO.
Does it work with the screen locked?
Partly. Speed, distance and route keep recording with the screen locked. For the technique analysis, keep the screen on. On Android the app keeps the screen on by itself while it records. On iPhone, turn the brightness down and switch Auto-Lock off for the time you ski.
Is there a subscription?
No. Every purchase is a single payment. The Season Pass ends on 30 April and does not renew.
Does it work indoors?
Yes. Indoor Training Mode is included in every version. Choose Indoor under Ski Mode in the settings or enter your hall's code.
Does it work in every country?
Yes. The app has no region locks. Outside, it only needs GPS, and it works the same way in the southern hemisphere season.
How long does the battery last?
That depends on the phone and the temperature. As the battery runs down, the app reads the sensors less often to save power. Cold drains a battery faster, so start the day fully charged.
Which phones does it run on?
iPhones with iOS 16 or later, and Android phones with Android 8.0 or later.
Which languages does the app use?
English, German, French and Italian.
Does fall detection call for help?
Fall detection is off until you switch it on. After a hard impact it asks whether you are OK. If you tap for help, it opens a call or a text message with your location to a contact you choose. If you don't respond, nothing is sent. It does not call emergency services, and it is not a certified safety device.
