## What is ZoneLight?

Transform your training with real-time visual zone feedback. ZoneLight connects your power meter or heart rate monitor to LED light bars and strips, showing you exactly which training zone you're in - instantly.

Perfect for indoor cycling (app agnostic so works with Zwift, Rouvy, TrainerRoad, Wahoo SYSTM, MyWhoosh, etc), indoor running, or any structured workout where staying in the right zone matters.  Can also be used as a standalone monitor (again, showing the zones) for HRM & Power  - great for seeing your HR exploding when the gym spin class is in full swing!

TRAIN IN THE RIGHT ZONE, EVERY TIME

ZoneLight turns your workout space into a visual training environment. Connect your power meter or heart rate monitor, add LED lights, and see your training zones light up in real-time - no more squinting at screens during hard intervals.

INSTANT VISUAL FEEDBACK
• LED lights change colour as you move between zones
• Power zones based on your FTP (6 zones)
• Heart rate zones based on your Max HR (5 zones)
• Built-in display shows current power/heart rate and zone

WORKS WITH YOUR EQUIPMENT
• Compatible with Bluetooth power meters (Wahoo, Garmin, Stages, and more - requires dual-channel BLE devices to simultaneously work with other bike training apps)
• Works with Bluetooth heart rate monitors
• Supports popular LED strips (ELK-BLEDOM, SwitchBot, MELK, and generic Bluetooth LEDs)
• Customize zone colours for both screen and LED lights

PERFECT FOR
• Indoor cycling sessions and smart trainer workouts
• Enhancing experience of indoor cycle training apps (use in conjunction with them)
• FTP tests and interval training
• Heart rate-based running on treadmills
• Any structured workout where zone discipline matters

SMART FEATURES
• Automatic zone calculation from FTP or Max HR
• 3-second power smoothing to reduce spikes
• Full-screen mode for distraction-free training
• Custom zones and colours
• Simulation modes for testing your setup and calibrating your colours

Whether you're grinding through sweet spot intervals, testing your FTP, or staying in Zone 2 for endurance work, ZoneLight keeps you visually locked into the right intensity - without breaking focus.

Download now and transform your training space into a visual zone laboratory.
