About this app

Healthy Weather: Your Daily Sun & Vitamin D Guide

Healthy Weather turns sunlight into something you can actually plan around. See exactly when your body can make vitamin D, how strong the UV is, and how much sun you've had — in a clean, science-backed app that runs entirely on your device.

At its heart is a custom Vitamin D Index that models how your skin produces vitamin D₃ from sunlight — using your skin type, age, exposure and live conditions, not a generic chart.

Free Features:

- Today at a glance: your Vitamin D window, sun-risk hours, feels-like and current conditions

- A plain-language daily summary of your sun day

- Tap any tile for an explanation and a mini graph

- Vitamin D Tracker: 5 free sessions to try it out…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
