Classic and skate are different sports, and inside each one the technique changes with every hill. Skibuddy reads your skiing from your phone's motion sensors and names the technique as you change it, from diagonal stride on the climb to double poling on the flat.

Skibuddy measures the rhythm of every stroke
For stride rate, Skibuddy counts your stroke cycles per minute. For glide, it divides your speed by that rate to give the meters you travel with each cycle. For balance, it measures how much of your sideways movement goes left and how much goes right. You see all three live on the session screen and again in the debrief.
You declare classic, skate or mixed when you start. Within that, Skibuddy recognizes diagonal stride, double poling, herringbone, V1, V2, V2 alternate and the downhill tuck from your speed, the grade and the way the phone moves.
Choose the pocket once
In a chest or jacket pocket, Skibuddy measures everything. In a pants pocket it still measures stride rate, but your legs swing too much for balance, so Skibuddy switches balance off and tells you why. Skibuddy remembers the pocket for every later session.
Skibuddy speaks up mid-climb
Switch on technique cues and Skibuddy watches your balance on every climb. When your left/right balance over the last 20 seconds leaves 45 to 55%, Skibuddy tells you out loud which side you lean to, then waits at least 90 seconds, and until you're centered again, before it speaks again.
A running tracker
Cross-country skiing, 1:12:05
Your watch files an hour of double poling, V2 and herringbone as one activity, with one pace and one heart rate.
Skibuddy
V2, 42% of the session
Skibuddy shows 8.4 m of glide per cycle at 152 bpm, next to the same numbers for V1 and double poling.
Skibuddy breaks down every session by technique
After every session, Skibuddy lists the four techniques you used most, with the share of the session, the glide and the heart rate for each. It draws your left/right balance for the whole session and lays cadence and balance over the map, so you can find the climb where your left side faded.
