Extremely simple. is just an app that opens a red screen on which you can change the brightness inside the app... I think this app would be great if it could modify the phone brightness as a whole. Cause if I wanted to use it as a torch at night, I would have to raise the brightness of my phone and then open the app, which makes it kind of pointless. Also,.you should enable a timer so the phone can turn off and not be on red light the whole night, which can be especially dangerous for Oleds

I really like its simplicity. Only thing I wish could be fixed is the adjustment bar. I wish it would disappear after a few seconds of non use, or that it was black, or both. I have extreme photophobia, and just that little blue light in the bar can agitate it. Other people perhaps aren't so sensitive.

Works pretty well but Android OS9 has a colour screen filter in the accessibility settings now so I've been using that instead since I upgraded to the Note 10+ 5G, not sure if it's on every version of Android 9 though. If not, this is your best bet. I did a full virus scan and didn't find any issues
