Body Battery turns your Apple Health data into one number you can actually act on: today's energy, from 0 to 100.
Every morning it reads the signals your body left overnight — resting heart rate, heart rate variability (HRV), sleep, wrist temperature, breathing rate, blood oxygen and yesterday's activity — and blends them into a single Body Battery score. A full battery means you are recovered. A low battery means your body is spending energy on something else.
WHY IT IS DIFFERENT
Everything is measured against YOUR baseline, not a generic "normal". The app learns your personal range from months of Health history, so a resting heart rate of 58 can be excellent for one person and an early warning for another.
WHAT YOU GET
• Today — one energy score, a clear label from Very Good to Very Bad, and a 30-day trend.
• Body status grid — recovery (resting heart rate), stress (HRV), temperature, breathing rate, blood oxygen, sleep duration and sleep efficiency, plus training load.
• Compared to your normal — every tile shows how today sits against your own baseline, with colour bands instead of raw numbers you have to decode.
• My Body tab — a dedicated 30-day chart for each metric, with trend arrows and colour zones.
• Plain-language explainers — tap any metric for what it means and one practical thing to try.
• Home screen widget — today's energy at a glance, in small and medium sizes.
• Automatic updates — new Health data refreshes your score in the background.
USE IT TO DECIDE
• Train or rest — low energy plus poor recovery is a clear sign for an easier session.
• Catch a bad day early — temperature, breathing rate and resting heart rate moving together often show up before you feel it.
• Track recovery — watch your numbers return to baseline after illness, travel or a hard training block.
• Manage stress — see how a heavy week actually lands on your body.
PRIVACY
Your health data stays on your iPhone. No account, no upload, no ads, no data selling. You choose which Health categories to share and can revoke access any time in the Health app.
WORKS BEST WITH
An Apple Watch, or any device that writes sleep and heart data into Apple Health. The more nights of data, the sharper your baseline.
IMPORTANT
Body Battery is a wellness and education tool. It is not a medical device and does not diagnose, treat or give medical advice. If you feel unwell, talk to a qualified healthcare professional.
