Nixie Tube Clock Widget LITE is a free clock widget app for Android that brings the vintage feel of Nixie tubes to your device. This app is perfect for those who love the retro look and feel of old-school technology. With this app, you can choose between 12-hour and 24-hour time formats and enjoy the high-resolution graphics that are perfect for tablets.

One of the coolest features of this app is that it uses photos of real Nixie tubes to display the time. The app offers three default widget sizes (4x2, 3x1, and 2x2) and resizing support for Android versions 3.1 and above. You can also choose between two widget types and enable the "Show seconds" mode, which displays the seconds but can lead to increased battery consumption. Finally, you can click on the widget to activate the fullscreen mode, which features a crossfade animation of the digits.
