Several features of the Plus version can be configured with the Settings application. You can change the background color, select your key click sound and adjust key click volume.

Like the original app, the Plus version is very simple to use. Merely tap the C, F, K, R or N key to select your entry mode and start typing the temperature value that you want to convert. Conversions to all the other temperature scales are performed instantly as you type, so there is no need for a Done or Enter key.
