Dark Theme for All Apps is a free personalization app developed by devios for Android. This app is designed to activate dark mode on devices that do not support it in their system settings. The app offers three modes - dark theme, auto mode, and day mode, allowing users to change the theme of their device according to their preferences. The night theme option activates dark mode for all apps, while the auto mode feature automatically changes the theme of all apps based on the time of day.

In addition, the app also has a blue light filter to protect the eyes from the harmful effects of blue light. Users can choose from a variety of colors for the filter and set a start and end time for it to turn on and off automatically. This feature helps reduce eye strain, especially for users who spend long hours on their phones.

Dark Theme for All Apps is easy to use and provides a beautiful user interface. It also helps save mobile battery since it does not use white lights. The app is compatible with Instagram and other apps that support dark mode. Overall, this app is a great choice for anyone looking to activate dark mode on their device and protect their eyes from harmful blue light.
