For iPhone · Free to start · Optional Plus subscription
Beyond the numbers
Your measurements tell part of the story. See how they fit together, what changes over time, and what’s usual for you.
Explore connections in your own history. Findings start as building evidence and are confirmed only when they keep holding.
On your higher-steps days,
deep sleep tends to run higher.
Understand daily readiness and recent changes against your usual range. Your own history gives the numbers meaning.
A picture of change, with your usual range in view.
A private Feel check-in connects the measurements with your lived experience. Because a number can’t tell the whole story.
Weekly and Monthly Reviews bring together what changed, what held, and what’s still uncertain. Your first Weekly Review is free.

The connections matter
Sleep, recovery, movement, and cycle context don’t happen in isolation. Explore them together through the history you choose to share from Apple Health.
Personal means private
Your health data, check-ins, reviews, and explanations are processed on your device. They aren’t sent to Reasons Within.
Optional usage analytics helps improve the app. It never includes your health data or personal notes.

Reasons Within is an iPhone app that uses the Apple Health history you permit to reveal personal patterns in sleep, activity, recovery, and more. It compares measurements with your own baseline and lets you add private Feel check-ins.
You need data in Apple Health. Some measurements require an Apple Watch or another compatible device. The insights available depend on the data and history you share.
Patterns need enough consistent personal history. A finding may appear as building evidence first and becomes confirmed only when it continues to hold. The app can stay quiet when the evidence is too limited.
Your health data and personal content are processed on your iPhone and are not sent to Reasons Within. Optional analytics includes limited usage and diagnostics, never health measurements or personal notes. Read the Privacy Policy for details.
Daily readiness, Feel, Health, Trends, Pattern Evidence, and your first Weekly Review are free. Plus adds ongoing reviews, eligible recovery forecasts, an eight-week Bio Age trajectory, and a private archive.
No. Reasons Within is a general wellness and self-knowledge tool. It is not a medical device and does not diagnose, treat, or provide medical advice.
Your history is a good place to begin.
