Not the screen. The pull. Dimly keeps the apps, categories and websites that take your hours closed while you focus, using Apple's Screen Time.
Pick a length and the apps you chose stay closed until it's over.
Mornings, work hours, bedtime. Plans switch on by themselves, even with Dimly closed.
Time you protect raises it. Calm days build a streak, and a dim pass covers the odd off day.
Your choices stay on your iPhone. Dimly never learns which apps you picked.
