Collect and export data using blue tooth

[William Fraser]

I am seeking guidance from this forum so that I can educate myself about the components necessary for something I want to "invent". I want to build a scale that records changes in weight and transmits the time and amount of weight change via blue tooth to an app. I think I need 1.) a scale, 2.) some device to collect and store the data the scale is generating, 3.) some device that transmits the data using blue tooth and possibly internet to 4.) an app on a smart phone. What are the devices that could accomplish steps 2 and 3 called?
