@Claude31 Hi Claude. I definitely need help with this. This is my app so far. See screen recording -> https://www.dropbox.com/s/zm1ogvijrz4xpmw/SR_01.mov?dl=0 >>>> I can achieve this with Timer or second but I'm unable to wrap my head around the logic for it. Case Moon button should activate night mode and sun button is for normal mode.

Will provide it ASAP.
