An iPhone app for instructor-free bike and treadmill workouts. Each workout shows target cadence and resistance (or speed and incline on a treadmill), seated or standing, effort and a timer for every segment, with soft cues before each change. There’s no instructor and no music, so you can listen to your own podcast, playlist or show.

Any stationary bike with a resistance knob or levels, including Peloton, Schwinn IC4, Bowflex C6, Echelon, NordicTrack, Keiser M3i, Sole and Yosuda. You set resistance by hand to match the cue. If your bike shows resistance on a different scale, use Bike resistance scaling in Settings (50 to 120%) to match it.

No. Every cue works without one. If your bike broadcasts cadence and power over Bluetooth (Fitness Machine, Cycling Speed and Cadence or Cycling Power), Cue Cardio shows your live rpm against the target and saves cadence and power with the ride.

Most bikes allow only one Bluetooth connection at a time. Close other apps that might be connected, like Zwift or your bike maker’s app, then start pedaling to wake the bike. In Cue Cardio, open Settings, then Sensors, and pick your bike. Make sure Bluetooth is allowed for Cue Cardio in iOS Settings.

With no remembered bike, the app only auto-connects to a bike that’s close by, so it won’t grab a neighbor’s bike at the gym.

Yes. Put on a Bluetooth chest strap or armband, then pair it in Settings, then Sensors. Your bpm shows on the ride screen, and your average and max are saved with the ride. If the strap stops sending beats, the chip shows “strap lost” until it reconnects.

Yes. By default cues mix over whatever’s playing. Prefer the other audio to dip for a moment? Turn on ducking in the app’s audio settings. You can also change cue volume, turn haptics on or off and turn on voice cues.

Cue Cardio uses the best English voice installed on your iPhone. For a more natural voice, download an Enhanced or Premium voice in iOS Settings under Accessibility, then Spoken Content, then Voices.

Yes. Start a ride, then switch to your video app. The ride continues in a small Picture in Picture window with the countdown and live rpm. It also shows on your Lock Screen and in the Dynamic Island as a Live Activity.

Three workouts are free forever: two bike rides, including a beginner ride, and a treadmill hills workout. Every feature works on them. Cue Cardio Plus unlocks every workout in the library and new workouts as they’re added. Plus comes with a 7-day free trial for new subscribers, then renews monthly or yearly at the price shown in the App Store.

Subscriptions are managed by Apple. To cancel, open iPhone Settings, tap your name, then Subscriptions, then Cue Cardio. If you cancel during the free trial, you won’t be charged. To restore a purchase on a new phone, open Settings in the app and tap Restore. For refunds, use Apple’s reportaproblem.apple.com.

The treadmill is here: 9 treadmill workouts ship alongside the 21 bike rides. Rower and elliptical come next. Follow @CueCardio on YouTube for new workouts.

The first version is for iPhone with iOS 17 or later. Apple Watch and Apple Health support aren’t available yet.

Only on your iPhone. There’s no account, and we don’t collect personal data. Deleting the app deletes your history. The app sends a few anonymous usage counts, like which workouts get finished, and you can turn them off in Settings, then Share anonymous usage. See our privacy policy.

There are beginner and low impact rides, and every ride shows effort out of 10 so you can go easier. Cue Cardio isn’t medical advice. Check with your doctor before starting a new exercise program, and stop if you feel pain, dizziness or shortness of breath.
