Built for the road
Everything you need on a ride. Nothing that gets in the way.
Live ride
Numbers you can read at 30 km/h.
A huge hero number, your recent trail on the map and an effort bar. Lap, Pause and Finish sit right where your thumb is.
- Heart-rate and power zones as a colour bar, from your own zone settings.
- Swipe between pages: Ride, all data, and navigation.
- Display lock against pocket taps. Recording never stops.

All data
Every metric. One swipe.
Twelve fields at once, and you pick them and their order. Missing readings show as a dash, never as a made-up zero.
- Choose and reorder fields, with saved layouts for outdoor and indoor rides.
- 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.

Apple Watch · Premium
Your wrist, if you want it.
Ride with just your iPhone, free. With Premium, choose Apple Watch next to Start, and your Watch records the workout with heart rate while your iPhone mirrors it.
- 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.

Progress
Progress that pulls you out the door.
Weekly progress, goals, your streak and badges you earn from your own rides. Nothing is pre-awarded.
- 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.

Ride summary
Relive every kilometre.
Your route on the map, your distance, time, speed and climb, and an analysis of zones and power when you want to go deeper.
- Routes: import GPX, save your favourites and follow their line.
- “Where to?” turn-by-turn directions with Premium, where Apple Maps offers cycling routes.
- Exports of your account archive, free.

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
