Glo - By Oral-B is an iPhone application developed by Guangzhou Procter & Gamble Technology Innovation Co. Ltd. This free lifestyle app connects with the Glo electric toothbrush via Bluetooth. Users input their personal information, including lifestyle habits, oral care needs, and whether they are first-time electric toothbrush users. The app then matches this input with recommended brushing modes by dental experts and transmits the mode to the electric toothbrush handle with a touch screen. When users start the toothbrush, the recommended mode initiates automatically, with a countdown timer to ensure the recommended brushing duration, after which the toothbrush stops automatically.
