ReMind / Phone accessories


ReMind is a screen protector that reminds people when they use their smartphones too much. ReMind is painted with temperature sensitive ink. The screen protector automatically fogs up when the phone’s temperature rises, which is when the user is overusing the phone. Since the feedback is triggered by the heat of smartphones, it won’t cost any additional energy, make everything more simple ,easier and eco-friendly.
