Bluetooth Enabled Umbrella
This invention is a bit much. There is a company that produces Bluetooth-powered umbrellas that also enable a GPS tracker. If you ever lose your umbrella (which happens a lot!) then you'll be able to figure out where you left it. You can also get interesting weather statistics if you're into that sort of stuff.
The Tampon App
My Flow is a literal brand new technology for periods. The company created tampons that help gather information on someone's flow. It's pretty simple! Although, it could be seen as a little inconvenient. You do have to keep a device in your pocket (or somewhere else on your person) in order for the device to read your flow. It could be a lifesaver, though!
