Blackr simulates a locked screen like state over any app, and does not stop them from running. Simple and smart design makes it very easy and convenient to use.

Please note - Since Android 8.0 (Oreo) or higher, navigation and status bar can't be hidden completely due to OS security reasons.

This is NOT a lockscreen app but an overlay like app, on OLED screens this is like turning the screen off but the phone isn't in sleep mode.

Best way to use the app is, add a blackr button in the quick settings in device status bar. It works seamlessly any time!

App Feature List:
- Keeps app running and screen essentially off.
- Run app using notification or floating icon.
- Supports quick tiles in in notification bar.
- Highly customisable design.
- View date, time, and battery percentage.
- Motion clock to prevent burn in or can be turned off completely.
- Optionally disable device from sleeping.
- If enabled, auto restart after device reboot.
- Very small app size and extremely efficient app.

Runs great on devices like Google Pixel, Samsung Galaxy, Note, OnePlus and more.
It works by showing a black overlay on top of the screen and on modern AMOLED displays this turns off all pixels, effectively turning the screen off.

Please note this is NOT a lockscreen app, It is an overlay, and your phone is not sleeping while this is on. So power reduction is mostly from less screen usage, and helpful to prevent screen burn in.

Primarily developed for turning screen on easily while developing apps, this app can be used in many scenarios like recording long videos, watching videos online for playing music, etc.
Blackr可以模拟任何应用程序的锁定屏幕，就像状态一样，并且不会阻止它们运行。简单而智能的设计使其非常易于使用。

请注意-由于Android 8.0（Oreo）或更高版本，由于操作系统安全性原因，导航和状态栏无法完全隐藏。

这不是锁屏应用程序，而是类似叠加层的应用程序，在OLED屏幕上就像关闭屏幕，但手机未处于睡眠模式。

使用该应用程序的最佳方法是，在设备状态栏中的快速设置中添加黑色按钮。它可以随时无缝运行！

应用功能列表：
-保持应用程序正常运行并关闭屏幕。
-使用通知或浮动图标运行应用。
-在通知栏中支持快速平铺。
-高度可定制的设计。
-查看日期，时间和电池百分比。
-防止烫伤或可以完全关闭的运动时钟。
-（可选）禁止设备进入休眠状态。
-如果启用，则在设备重启后自动重启。
-非常小的应用程序大小和极其高效的应用程序。

在Google Pixel，三星Galaxy，Note，OnePlus等设备上运行出色。
它通过在屏幕顶部显示黑色覆盖层来工作，而在现代AMOLED显示器上，它将关闭所有像素，从而有效地关闭屏幕。

请注意，这不是锁屏应用程序，而是叠加层，打开后您的手机没有处于睡眠状态。因此，降低功耗的主要原因是屏幕使用量减少，有助于防止屏幕烧伤。

最初开发该应用程序是为了在开发应用程序时轻松打开屏幕，该应用程序可用于许多情况，例如录制长视频，在线观看视频以播放音乐等。


在不停止运行的应用程序的情况下使屏幕变暗（对于OLED而言显示为关闭）。
