I would like to recommend that the developers consider integrating a black-and-white (grayscale) mode into the app.
Using Opal in combination with my phone’s grayscale mode has significantly improved my focus and helped me drastically reduce my screen time. Without colors, the phone becomes far less stimulating, and I find myself using it only for essential tasks.
I believe this feature could be a powerful addition for users who want to reduce distractions and improve their digital habits.
