About this app

Cyclone turns your smart trainer or turbo trainer into a full indoor cycling studio — structured ERG workouts, live power data, and ride analytics, with no ads and no data collected.

NO ADS. NO ACCOUNT. NO DATA COLLECTED.
Cyclone doesn't track you. There's no account to create, no ads, and nothing shared with third parties — this is Cyclone's own declared Google Play Data Safety status: "No data shared with third parties" and "No data collected." Every ride stays on your device.

SMART TRAINER & TURBO TRAINER CONNECTION
Pairs with any FTMS-compatible Bluetooth smart trainer or turbo trainer. Live Indoor Bike Data: instant power, cadence, speed, distance, and heart rate. Automatic reconnect between sessions.

STRUCTURED WORKOUTS — ERG MODE
Seven built-in training profiles: Easy Spin, Endurance, Sweet Spot, Tempo, Threshold, VO2 Max Intervals, and Cooldown. Each segment targets a percentage of your FTP; Cyclone pushes the exact wattage to your trainer automatically — true ERG-mode indoor cycling, no guesswork.

FREE RIDE MODE
Real-time panels for power, cadence, speed, distance, heart rate, and trainer resistance. Live rolling power chart. Inline resistance controls. Screen stays on during rides.

CUSTOM WORKOUT BUILDER
Design your own ERG intervals segment by segment — warm-ups, efforts, and cooldowns, each with its own duration and %FTP target.

HEART RATE MONITOR SUPPORT
Connects to any standard Bluetooth heart rate strap independently from the trainer. Cyclone prefers strap HR over trainer HR when both are present.

WORKOUT HISTORY & ANALYTICS
Every ride saved locally on your device. Post-ride analytics include power and heart rate zone distributions, normalised power, intensity factor, and TSS. Full per-second history charts on every workout.

CUSTOMISATION
Set your FTP for accurate zone targets. Toggle between metric and imperial units. Cyclone remembers your paired trainer and HR strap between sessions.

PRICING
Basic riding is free forever. ERG structured workouts, analytics charts, and power/HR zone distributions unlock with a Cyclone subscription (monthly or annual, cancel anytime).

REQUIREMENTS
• An FTMS-compatible Bluetooth smart trainer or turbo trainer
• Android phone with Bluetooth Low Energy support

Ride with momentum.
