A final smartphone-connected gadget for seniors (or anyone who takes a lot of pills) is the clever uBox. This round, functionally designed box reminds people when it's time to take their pills with a combination of beeps, blinking lights and smartphone reminders.

If they've already taken the pill for that time period, the box remains locked so anyone who is forgetful or suffering from dementia won't take a double dose. The uBox will notify family members or health care providers if a dose is skipped. The company, founded by MIT engineers, is raising money on Indiegogo.
