Kolibree is a company based in France that is known for developing a smart toothbrush. Colibri means "hummingbird" in French; perhaps a reference to their signature product's light weight, about 64g.
Design
The toothbrush connects via Bluetooth to a smartphone app and can tell users whether or not they are brushing well. Also available is a choice of video games, in which good brushing is rewarded with high scores in the game. The toothbrush has removable heads; thus the same brush can be shared by different people without worry of contamination.
