# Sun Exposure

Adjust the slider to any date & time you want to see and the map will update in real-time.

{% hint style="success" %}
**Supported Platforms**

iOS
{% endhint %}

<figure><img src="/files/zOtpq67dTBkXqv2DYddw" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
You can change the date by tapping on the time above the slider. This will put the slider into date mode and when you scrub it will change the date while keeping the time constants. This is cool for seeing how the sun angle changes over the course of the year.
{% endhint %}

### Why only iOS?

This layer uses low-level GPU rendering to make it as fast as it is. This requires extensive platform-specific development time, but we hope to bring it to other platforms soon!
