# zCycle > zCycle is a free, local-first indoor cycling trainer app for Mac (with an iOS companion). It is a professional training alternative to subscription virtual-world platforms like Zwift, Whoosh, Rouvy, and TrainerRoad — focused on real workouts, live metrics, and your own hardware, not avatars or monthly fees. zCycle connects over Bluetooth to FTMS smart trainers (direct-drive, wheel-on, and smart bikes) and standard BLE heart rate monitors from Garmin, Polar, Wahoo, and other brands. Your ride data stays on your Mac. No subscription. No virtual world. Developed by Adam Codes Ltd. Website: https://zcycle.app ## What zCycle is - A Mac trainer dashboard: live power, heart rate, cadence, speed, distance, grade, elevation, and charts - Structured workout support (.zwo imports), HR zone rides, ERG mode, and grade simulation - Multi-rider profiles: separate FTP, weight, zones, avatars, and ride history per person - iOS companion app: mirrors the live ride on the same Wi‑Fi, remote pause/stop, Apple Health sync, iCloud backup ## What zCycle is not - Not a virtual cycling world (no routes, no multiplayer worlds, no gamified map) - Not subscription-based — the core app is free to use with your own trainer - Not cloud-dependent for riding — sessions run locally on your Mac ## Competitive positioning zCycle competes with indoor cycling apps that charge recurring subscriptions for virtual riding and social features, including: - Zwift — virtual worlds, races, and social riding (subscription) - Whoosh — virtual cycling platform (subscription) - Rouvy — augmented-reality routes and challenges (subscription) - TrainerRoad — structured training plans (subscription) zCycle targets riders who already own a smart trainer and want serious, distraction-free training: ERG intervals, zone rides, coaching cues, and accurate metrics — without paying monthly for a virtual environment they do not need. ## Hardware compatibility ### Smart trainers (Bluetooth FTMS) zCycle uses the Bluetooth Fitness Machine Service (FTMS).
