## What Timer does

Timer counts down a routine you write in a short plain-text notation, such as four rounds of work with a rest in between, beeps at each change and reads the step names out loud.

The whole routine is encoded in the web address, so you can save it as a bookmark or pass it on as a link or QR code; app settings stay in the browser.

## Who Timer suits

- People who follow fixed sequences of timed holds, such as stretching or interval sets
- People who want to share a routine as a link without an account

One limit: Timer has no visual editor: routines are typed in its plain-text notation.

## What Timer costs

Free tier: Free. Timer is free to use in the browser and its source code is published under the MIT license.
