UNTILL is a mobile app that gamifies and rewards for how you unscreen. You can unscreen solo. You can unscreen with others around the world. You can unscreen with friends and family right where you are. How you unscreen is how you score points! --- When UNTILL is open the foreground, the FILL timer logs your unscreen time. UNTILL rewards you for FILLs, which are blocks of uninterrupted time. 15 min = 1 FILL point 30 min = 2 FILL 60 min = 5 FILL The FILL timer interrupts and resets when you close UNTILL, open another app in the foreground, or lock your phone. --- Unscreen with others to score SYNC points. Players who SYNC and complete FILLs together, score points together. Create a SYNC that other players join to score HOST points. --- The foundational game loop for UNTILL is: UNSCREEN > SYNC > FULFILL UNSCREEN when you play UNTILL SYNC with others, because it’s more fun to UNSCREEN together! FULFILL and feel rewarded for how you UNSCREEN --- Our purpose is to encourage people to reclaim their Time and Attention, and to value authentic human connection. We envision a world where the benefits of being off-screen outweigh those that tether us to our devices.
