Smart trainer workouts for iPhone
Simple Cycle turns your smart trainer into a precise interval coach. Build a workout from exact watts or your FTP power zones, press start, and the resistance changes on every interval while you focus on pedaling.

How it works
No subscriptions, no virtual worlds, no leaderboards. Just the intervals you want, held to the watt.
Add intervals as exact watts, or pick a power zone and Simple Cycle works out the watts from your FTP. Duplicate blocks, repeat an on/off pair in one tap, or import a workout you already have.
Give the pedals a turn and Simple Cycle finds your trainer over Bluetooth. It remembers it next time and reconnects on its own if the signal drops. Pair a heart rate strap the same way.
Works with trainers that support Bluetooth FTMS, including Wahoo KICKR, Tacx and Garmin, Saris, Elite, Zwift Hub and most models from the last few years.
In ERG mode the trainer holds your target no matter your gear or cadence. Feeling strong or cooked? Nudge the whole workout up or down 5% at a time.
Bring your own gear and workouts
Pair a chest strap or armband once and Simple Cycle reconnects every ride. Your heart rate shows on the ride screen, is recorded every second, and goes to Strava and Apple Health with the rest of your data.
Works with monitors that use standard Bluetooth heart rate. If your trainer also reports heart rate, the strap takes over while it's connected.
Tap the import button, pick a file from Files or iCloud Drive, and review it before saving. Workouts written as a % of FTP stay that way, so they get harder as you get fitter.
Ramps become short steady steps, ready to ride in ERG.

Your rides, where they belong
Connect once and every ride uploads as an indoor trainer activity, with the full power graph your friends can kudos.
Rides are saved as Indoor Cycling workouts, so they show up in the Fitness app next to everything else you do.
Turn on automatic export and there's nothing to tap after the cool-down. Prefer to choose? Every ride waits in Ride History with Save and Upload buttons.
Simple Cycle is in beta on iPhone. Leave your email and we’ll send you a TestFlight invite as soon as the next build is ready.
