## What is Distance to Sound?

DTS lets you estimate the distance between an event that you can see (a firework exploding, a bolt of lightning flashing across the sky or a rocket taking off) and your current location. It uses the time it takes for the sound created by the event, adjusted for the temperature of the surrounding air (a setting which you can easily adjust), to estimate the distance between you and the event.

Using Distance to Sound is about as easy as it gets.

- Wait for a flash of light created by the event, then quickly press the center button

- Wait for the sound of the event to reach you.

- Quickly press the button again.

## Key features

- Estimate distance to visible events
- Measure time between light and sound
- Adjust for air temperature
- Simple, intuitive interface

### 5/5 — Awesome little app!

*2022-07-16, version 1.0*

Good app with simple controls that don't take a manual or programming degree to understand how to operate it:)

### 5/5 — Great app!

*2022-07-05, version 1.0*

I love this app. Great for seeing how far fireworks are on the fourth of July. Although one thing i would like to see added is the click radius to start the timer being larger because i miss the button sometimes watching for fireworks.
