Balanzia vs VO2 Max Tracker

Balanzia helps you understand how your body is really doing – every day and over time. Using your Apple Health data, Balanzia estimates your biological age, daily body battery and recovery state, so you can balance training, sleep and stress more intelligently. --- TODAY DASHBOARD --- • Recovery State See how ready your body is today based on overnight HRV, resting heart rate and sleep. Get a simple recommendation: go hard, train light, or rest. • Body Battery Track your daily energy level as a “battery” from 0 to 100. Night-time sleep, daytime activity, training load and stress all charge or drain your battery. • Biological Age Compare your “health age” with your calendar age. Balanzia combines cardio fitness, nervous system balance, sleep patterns, activity and body composition into one simple number. • Weekly Summary Review the last 7 days at a glance: trends in sleep, load and energy, plus 1–2 concrete actions to improve your recovery next week. --- HEALTH INSIGHTS --- • Cardio Fitness Monitor your VO2max and resting heart rate trends over the last months. See if your cardio fitness is improving, stable or declining. • Sleep Score Understand your sleep duration, regularity and sleep debt for the past week. Learn when you are consistently sleeping too little (or too much). • Training Load Visualize hard days and recovery days, weekly load vs. your usual baseline, and your acute/chronic ratio. Avoid both overload and long periods of undertraining. --- GOALS & PERSONALIZATION --- • Set your personal sleep goal and daily activity goal. • Choose your main focus: Sleep, Recovery, Training or Overall Balance. • Balanzia adapts its recommendations to your priorities over time. --- PRIVACY & APPLE HEALTH --- Balanzia reads data from Apple Health (such as heart rate, HRV, sleep, workouts, steps and VO2max) to calculate your metrics. Data is processed on your device and is not shared with third parties. Balanzia is a wellness app only.

Your VO2 Max, tracked the way Apple designed it to be. VO2 Max Tracker turns the fitness data your Apple Watch already collects into clear trends, meaningful milestones, and real motivation — no guesswork, no spreadsheets. WHY VO2 MAX MATTERS VO2 Max is the single best predictor of cardiovascular fitness. Apple Watch estimates it automatically from your outdoor walks and runs — this app shows you what it means and where you're headed. FEATURES • Live VO2 Max trend, fitness level, and percentile for your age and sex • Automatic record detection, with a celebration the moment you hit a personal best • Every workout linked to its exact VO2 Max impact — see which runs actually move the needle • Weight and sleep trends alongside your cardio fitness, all in one place • Smart notifications when you improve, trend down, or hit a streak — capped at once a day, never spammy • Full history and long-term trend charts, not just today's number BUILT FOR APPLE HEALTH Works with the VO2 Max, workout, heart rate, sleep, and weight data already in Apple Health. Nothing to set up beyond granting access once. PRIVATE BY DESIGN Your health data never leaves your device. No account, no cloud sync, no analytics, no ads. VO2 Max Tracker reads from Apple Health locally and stays there — that's the whole architecture. REQUIRES APPLE WATCH VO2 Max readings are generated by Apple Watch during outdoor walks or runs. An iPhone alone cannot produce this data — that's an Apple Health limitation, not ours. VO2 Max Tracker is not a medical device and does not provide medical advice.
