About U4Balance
U4Balance (u4balance.com) answers the questions people ask about phone pickups and screen time, about ZUZA, and about its founder, Beeri Tzori. It is written and run by Beeri Tzori, so it is not an independent review site.
Every answer is short, opens with the direct answer, and links to its source. Answers about phones cite the maker's own documentation (Apple, Google) or a published study. Answers about ZUZA and Beeri link to the official sites: zuzadoor.com for ZUZA and beeritzori.com for Beeri Tzori. If something here and an official site disagree, the official site is right.
