Before
You feel okay, say yes to normal plans, then spend the next few days recovering.
Body Insights turns generic Apple Watch data into clear guidance for your energy, recovery, and health.
Made for the days that don't feel like the others.

Body Insights is an Apple Watch recovery and pacing app for people whose energy changes from day to day.
It reads your Apple Health data and shows your available energy and what your body can handle today.
Decide what to take on, what to move, and when to protect tomorrow.

Use the health signals you already collect to make better daily decisions.
A morning recovery check that reads your overnight glucose - not just your HRV. For a body that doesn't follow a training cycle.

Plan around your body before it makes the decision for you.
You feel okay, say yes to normal plans, then spend the next few days recovering.
You see recovery is low before the day starts, move what can wait, and keep more of the week.

You bought an Apple Watch to understand your body. Then it gave you rings, charts, and sleep scores - but not the answer you needed before the day started.
Body Insights was built for that gap. It reads the signals already on your wrist and turns them into plain language you can act on.
We did not want another dashboard that showed more numbers. We wanted a translator.
Something that could look at HRV, resting heart rate, sleep, stress, glucose, and recovery, then say: "Today has more in it." Or "Today, take it slow."
On-device. No account. No data sold. Ever.

Real App Store reviews.
What Apple Watch users say after downloading Body Insights.
★★★★★
Perfect for us chronically ill peeps
"This is the app I’ve been needing. I have an Apple Watch, but had been considering getting a wearable through Visible to help with pacing. Now, I don’t need to do that. Body Insight has all the information I need to make sure I’m pacing myself properly to avoid a flare. Super affordable subscription too! The only thing missing that I wish it did… show insights from my glucose testing. I don’t have a CGM, but stick test frequently."
★★★★★
This app SAVED my life!
"It showed my cardio fitness implied i was 36 years older than my actual age. And falling. Doctors found two heavily blocked arteries which are now handled. If not for this app and Apple cardio fitness alerts, i may not have literally survived 2025."
★★★★★
This app has become indispensable
"I reviewed this app a year ago, but I wanted to come back to say that this app has become part of my daily routine. Completely indispensable - I cannot fathom how I lived without it. The data and what it presents is all so helpful, and the user interface is clean, clear and beautiful. This app should be on everyone’s Home Screen if you have an Apple Watch."
★★★★★
