CKcardio – Heart Rate Training with Zones CKcardio makes heart rate training simple, precise, and motivating. Whether you're running, cycling, doing HIIT, or training freely — keep your heart rate zones in view and train exactly where it counts. Live heart rate across five customizable training zones Rest, Recovery, Fat Burn, Anaerobic, and Maximum — set the exact heart rate range for each zone yourself, so the app adapts precisely to your fitness level. Support for Bluetooth chest straps and Apple Watch Connect your heart rate strap (e.g. Polar) or use your Apple Watch directly. If you often train in the same place with many sensors nearby — like at the gym — CKcardio remembers your sensor and highlights it the next time you search, so you can find it instantly. Guided and custom training programs Choose from suggested programs or build your own — with as many phases as you like, custom duration, and a target zone for each phase. You can also record a free workout and save it afterward as a repeatable program, with a handy smoothing feature for clean, rounded phase times. Training continues in the background Lock your iPhone or switch apps — your workout and heart rate tracking keep running reliably.
