Calibrate: Recovery & Fitness

Fitbit Air has arrived. Connect it up to Calibrate today!

Your body is talking. Calibrate translates.

Calibrate turns the data from your Apple Watch, Garmin, Whoop, Fitbit, and Apple Health into clear, actionable insight across recovery, readiness, sleep, and stress. No noise. No guilt. Just the information you need to perform at your best — in training, at work, and in life.

This is not about pushing harder every day. It is about knowing when to push, when to recover, and how the three pillars of your life — work, life, and training — affect each other.

Compete on Global Leaderboards See where you rank against everyone. Global leaderboards for recovery score, sleep score, daily strain, and steps. Running leaderboards for 1K, 5K, and 10K times and longest distance. Create private group leaderboards and compete with friends — across every wearable. No other app does this.

Daily Recovery & Readiness See how prepared your body is today. Heart rate variability (HRV), resting heart rate, sleep quality, and recent strain — distilled into a signal you can actually use. Supports Garmin Body Battery natively.

Sleep & Recovery Insight Understand how your sleep is shaping your performance and your mood. Consistency matters more than duration. Calibrate shows you both.

Training & Exertion Awareness Know how much load you are placing on your body and how well you are recovering from it. Train with precision, not just effort.

Stress & Wellbeing See how life stress, training, and recovery interact. Built for people who care about performance and mental health equally.

Trends That Matter Move beyond daily scores. Spot the longer-term patterns that separate sustainable progress from burnout.

Works With Every Wearable Apple Watch, Garmin, Whoop, Fitbit, and Oura — one unified dashboard. One leaderboard. No device lock-in.

Who Calibrate is for: People who train but refuse to burn out. Garmin and Whoop users who want their data unified. Those replacing or supplementing Whoop with smarter insight. People who believe recovery is not a rest day — it is a strategy.

Data & Privacy Your data stays yours. Calibrate reads health data from Apple Health to provide insights and does not sell your personal information.
