For you to be able to access the timer on your home screen moving forward, you would need to start the Timer via the following:
- via the Discover tab (1st tile of the 9 tiles)

- via your Profile (1st item under their stats)

- via the Home screen (if you've used the Timer in the last 4, soon 7 days)
You can start seeing Timer on the tile “My Day” section of the home screen once you start using it.

You can also add additional time by clicking on the Add 00:xx button.

You may also set your opening screen to timer when you go to your Profile icon (lower right) > Settings > Opening Screen > Timer so the timer will be the first to appear when you open the app.
