Find Your Line.
The cycling assistant built for riders who take their training seriously. Color-coded ride replays, AI ride coaching, and component-level wear tracking — all in one quiet, dark app.
Three systems. One quiet ride.
Crankd pulls together the things you used to spread across four apps and a spreadsheet — recording, coaching, and the parts on your bike.
GPS Recording
Precision GPS recording with heart-rate integration. Every ride mapped on a topographic canvas, ride replay built automatically. Record from iPhone or Apple Watch.
GPS Recording →Crankd Coach
Once you've saved 10 rides, Crankd Coach analyzes every ride against your recent history — calling out personal bests, trends, and rest gaps. Available on Crankd Pro.
Post-ride analysis →Biggest climb of your last six rides: 3,740 ft of gain, 590 ft more than your previous high.
First ride in six days. Your five before this came every two days.
38 minutes at Threshold, 21 in Tempo. Your max HR is estimated from age, so read the split as approximate.
Component Tracking
Chains, brake pads, tires, bottom brackets — every part has a service life. Crankd watches the wear so you don't.
Per-component telemetry →Honest tiers. No upsell on race day.
Free covers everything you need to ride and record. Crankd Pro adds the Coach and deeper training analysis.
