  • minimalist phone: An app designed to reduce phone addiction by adding grayscale for the apps we use most often (apps like TikTok are less attractive in black and white and we’ll reduce their use automatically).
  • Grayscale+: another great app to turn on grayscale automatically. Requires a special permission that can be activated via a PC (if we don’t have a rooted phone).
