Playbrush is an online store that facilitates a subscription-based business model (SBM), running on Shopify. They offer a subscription for smart toothbrushes that track your teeth cleaning. The toothbrush can connect to an application on your Android device or iPhone and give you tips on how to brush better. For children, there are specific apps that gamify the toothbrushing for them, making the process more enjoyable. For adults, there are apps that provide statistics on your brushing technique.
