The cycling computer in your pocket.

Live ride

Numbers you can read at 30 km/h.

  • Bluetooth sensors with Premium: heart-rate straps, speed, cadence and power.
  • Indoor rides on a trainer. Distance comes only from a wheel or trainer sensor.

  • Start on either device. The choice is remembered.
  • Live pages on the Watch, with zone colours and haptic turn cues when following a route.
  • One workout in Apple Health, never two for the same ride.

Never lose a ride

Saved. And it tells you where.

Every finished ride shows exactly where it is saved: on this iPhone, in Apple Health and in backup. If the app is closed mid-ride, CycleTron brings the ride back, paused, ready to continue or save.

  • Local first. Recording never needs a signal; maps may need internet.
  • Apple Health gets your workout when you allow it.
  • Optional backup in the EU with Premium, with export and deletion any time.

  • Ride history with maps, zones and climb for every ride.
  • Month and year trends and personal records, with Premium.
  • Share cards that can hide where you start and finish, with Premium.

Questions

Good to know.

Do I need an Apple Watch?

No. CycleTron records on your iPhone by default, for free. With Premium and an Apple Watch with CycleTron, choose “Apple Watch” next to Start and the Watch records the ride with heart rate, while your iPhone mirrors it.

Does it work without a signal?

Yes. Recording is local and never needs the internet. Map tiles and Apple Maps directions may need a connection.

Can I use a heart-rate strap or power meter?

Yes, with Premium: Bluetooth heart-rate straps and speed, cadence and power sensors.

Does CycleTron sell or share my data?

No. There are no ads and no tracking. Health data is never uploaded raw or used for marketing. The privacy policy lists every case where data leaves your iPhone, and why.

Can I get my rides out?

Yes. Your rides live on your iPhone and in Apple Health if you allow it. With an account you can export your cloud data for free and delete the account inside the app.

Does turn-by-turn work in my city?

“Where to?” uses Apple Maps directions, which are offered only where Apple has cycling routes. You can always import a GPX route and follow it.

Coming soon

Ride it all.

CycleTron is coming to the App Store for iPhone and Apple Watch. Want to know when it lands, or join the beta?
