Open.
On your iPhone, your Apple Watch, or both. No account.
6:00. Before the world wakes.
Indoor bike rides. Zero fuss. Open the app, it finds your smart trainer, you pedal. That’s the setup.
What’s missing
Nothing in the way.
From cold start to first pedal stroke in under ten seconds. No login, no pairing ritual, no menu between you and the work.
On your iPhone, your Apple Watch, or both. No account.
Your trainer wakes up and connects by itself. Watts appear.
Stop when you’re done. The ride is already in Apple Health.
See what matters
Power, heart rate, cadence and speed. Big numbers, one clean graph, nothing else on screen. Choose what the graph shows and forget about it.

Apple Watch
Start on your Watch and leave the phone in the other room. Heart rate from your wrist, watts from your trainer, both screens in sync. No iPhone nearby? Your Watch drives the trainer itself.




Control the effort

One swipe from your numbers. Change it from your iPhone or your Watch.
Apple Health
Every ride is saved to Apple Health automatically, with heart rate and calories from your Watch. Look back at peak power, power and heart-rate zones, and heart-rate drift: the honest measure of your endurance.

Your first five rides are free. Then $14.99, once.
For iPhone and Apple Watch. Apple Watch optional.
Free rides and unlock
Calmavelo is a free download. You try it with your own trainer first, and unlock it only if you want to keep riding. Here is exactly how it works.
Ride five times with your own trainer, nothing held back. A ride counts once it lasts ten minutes, so connecting and testing your trainer is free. Rides are counted in Apple Health, so reinstalling the app doesn’t hand out more. Used them all up? Take one more ride on us before you decide.
One in-app purchase of $14.99 unlocks every ride for good, on iPhone and Apple Watch. No subscription, no renewals, no ads, no upsell. Nothing else to buy, ever.
Buy it once and share it with your family. Everyone in your Apple Family Sharing group can use Calmavelo on their own iPhone and Apple Watch, at no extra cost and with their own rides in their own Apple Health.
Your unlock belongs to your Apple Account, not to one device. New iPhone? Tap Unlock, then Restore Purchase. If a parent has to approve the purchase with Ask to Buy, Calmavelo unlocks as soon as it’s approved.
Questions about buying or restoring? See Support.
Smart trainers that support Bluetooth FTMS (Fitness Machine Service). Most current direct-drive and wheel-on smart trainers do. Pedal once to wake yours and it shows up in the list.
No. With a Watch you get heart rate and calories from your wrist, and you can start and control rides from it. Without one, your iPhone records the ride and estimates calories from your power.
Yes. Start a ride on your Watch; if your iPhone isn’t around, the Watch connects to the trainer itself.
Into Apple Health, on your devices. There’s no Calmavelo account and no server that stores your rides.
Yes. Try five rides free with your own trainer. Then one purchase unlocks Calmavelo on your iPhone and Apple Watch for good. No subscription, no ads, nothing else to buy. How the unlock works
Yes. Calmavelo supports Apple Family Sharing. Once you’ve bought it, everyone in your family group can unlock it on their own devices at no extra cost. Family Sharing has to be turned on in Settings on your iPhone.
Open Calmavelo, tap “Unlock” and then “Restore Purchase”. Your purchase belongs to your Apple Account, so it works on every iPhone and Apple Watch signed in with it.
Make sure Bluetooth is on, pedal to wake the trainer, and close any other trainer app; most trainers only accept one connection at a time. More help.
