BoreSync is a mindfulness app. You sit with boredom on purpose. Solo or with friends. No music. No guides. Just a timer. Join a group with a code. See who is with you live. Switch apps? Get a 10-second penalty ("You blinked!"). After, see your score (time minus penalties). Write one note. Share it. Track stats and badges. Works offline. Add to iPhone home screen. Built fast with AI. Inspired by digital detox. Try it: boresync.com. Who lasts longest?
