The app is designed to be very simple and self explanatory to use

Just click on the ☰ from the right top (three horizontal lines) to bring the menu (in case you forgot how you got here)

Choose a language of choice and choose the day of week. The next dropdown will list the songs chanted during that day. Click on the Load button to load the song

The RE- check box is used only by people who need the option to force downloading of the lyrics during editing process that normal users won't need

The main page now has the song loaded in a few seconds. The status bar below shows the progress (may take some time if you are on a slow network)

Once the song is downloaded you can play by using the player near the bottom (▶/⏸ button).

You can click and drag the audio player to seek any point of the song and the lyrics will be shifted and highlighted accordingly. Similarly, clicking on any line on the lyrics will bring the audio player to that position.

Clicking on the ⏩ button loads the next song for the day, in the same language.

Mobile browsers will provide an audio icon in the player to mute the song while playing while desktop browsers may provide ability to control the volume also

You can either simply bookmark the URL to revisit the app. In most latest and up to date mobiles, you will get an option to install this as an app from the browser's main menu.
