Best Overall (277 teams) · HackGT · Sep 2025

A pill bottle that weighs itself to tell whether grandma took her medicine today. If she misses a dose, her family gets a message before it becomes a problem.

Why it won: Between 30 and 50 percent of patients with long-term conditions do not take their medicine as prescribed, a quiet failure estimated to cost the US health system over $100 billion a year. The bottle addresses it with nothing but weight: no cameras, no buttons, nothing to remember or press. The best sensor turned out to be the one that cannot be forgotten.
