Kadens helps self-coached athletes progress for the long term. Most fitness apps stop halfway. Some focus on recovery. Others focus on training plans. Kadens is built to close the full loop over time: recovery, training load, planned sessions, what you actually did, and your progress, using the data that already lives in Apple Health. The first step is already live: understand whether your body can support the work ahead. โ–ถ TODAY Start each day with a clear recovery picture. โ€ข Last night's sleep at a glance โ€ข Morning body metrics compared to your usual range โ€ข Trends that show what is improving and what needs attention โ–ถ SLEEP Sleep drives recovery. Kadens helps you see if you are actually getting enough of it. โ€ข Sleep duration and sleep stages โ€ข 7-day sleep debt โ€ข Wake time compared with your usual wake time โ€ข 30-day trends for duration, debt, and wake consistency โ–ถ BODY METRICS See how recovered you are before you decide how hard to push. โ€ข Resting heart rate โ€ข Heart rate variability (HRV) โ€ข Respiratory rate โ€ข Blood oxygen โ€ข Wrist temperature Each metric includes a 30-day trend and a check against your typical range. โ–ถ WORKS WITH APPLE HEALTH You do not need an Apple Watch. Any wearable that writes to Apple Health can work, including Garmin, Oura Ring, Ultrahuman Ring, and others. Apple Watch usually gives the fullest picture. โ–ถ BUILT FOR THE LONG GAME Kadens is not a "do more" app. It is designed to help you train with intent: recover well, balance effort wisely, follow the session you planned, and see whether you are progressing on the path you chose. Coming next: training load guidance, structured sessions, planned vs actual analysis, and longer-term progress trends. โ–ถ PRIVACY Kadens reads your data from Apple Health on your device. Those readings stay on your device. Kadens is not a medical device and does not replace professional healthcare advice.
