### 2/5 — Needs Improvement

*2026-07-13, version 1.8.2*

This app should have two settings: sun exposure for Vitamin D and sun avoidance for skin health. It is focused on just sun exposure. Most people tracking the UV Index are trying to stay away from the sun. They have skin conditions (such as myself) or concerns and need to know which days have high UV levels. The app is nice, but completely geared toward “sun exposure goals.” UVA rays are a major factor in skin aging and sun causes DNA damage. Also, there are many conditions that make high UV dangerous (I am in that case) and sunlight in general. If this app is a sun-exposure-only app perhaps a different name would be well suited to make it clear to potential users.

### 5/5 — Great design, works well

*2025-07-11, version 1.0*

Will help me manage my sun exposure. Looks nice, is simple and easy to use.
