TV Mode with AirPlay

Put the run where it’s easiest to see.

Send a clean, high-contrast dashboard from your iPhone to an AirPlay display. Your live numbers get the big screen while pause, lap, and finish controls stay safely on your phone.

  • Read-only display—TV Mode never controls the treadmill
  • Live metrics, heart-rate zone, laps, and a finish summary
  • Customize the TV card mix and sizes with TreadSimple Pro

TV Mode requires a compatible AirPlay display. Live updates require TreadSimple to remain foregrounded and awake.

Activity View

Custom lapsChoose a lap distance, track progress, and review splits before saving.

Lock Screen statusFollow the workout with Live Activities and the Dynamic Island on supported iPhones.

Portrait or landscapeActivity View reshapes itself around the way you position your iPhone.

Your run keeps moving

Save here. Send it there. You choose.

Every completed workout is saved locally first. Review your totals, splits, and optional note—then share it with the services you already use.

Ready for your training log.

Upload a route-free indoor run with your metrics, lap splits, heart rate, and optional workout note. Turn on automatic sync if you prefer.

APPLE HEALTH

Fits into your health history.

Save an indoor run with duration, distance, active energy, and heart-rate samples. The transfer happens on your iPhone.

OPEN EXPORT

A file you can take with you.

Share a standards-based FIT file without fabricated GPS data—one workout at a time, or download your full archive with Pro.

Your complete Activity history, on-device.

Browse past workouts, open the details, revisit lap splits, retry exports, or delete the data you no longer want.

Simple at every step

The details that make it dependable.

Broad compatibility

Connect to many modern treadmills through the Bluetooth FTMS standard, without being locked to one equipment brand.

Compatibility depends on the treadmill model and its FTMS implementation.

Heart rate, together

Pair a standard Bluetooth heart-rate monitor alongside your treadmill and see BPM, zones, and workout data in one place.

Built to recover

Workouts save incrementally. If a connection drops, TreadSimple works to reconnect without sacrificing the run already recorded.

Useful without a feed

No social layer, profile building, coaching clutter, or treadmill-control surprises. Just connect, record, review, and save.

Start simple. Make it yours.

The essentials stay accessible.

Free includes two workouts over five minutes each week, the standard Activity View and TV Mode, local history, individual FIT sharing, Apple Health, and Strava. No core data is held hostage.
